48a50ee034 [android/process list] support showing process arguments
Summary:
The qfProcessInfo and qsProcessInfo packets currently don't set the processes' arguments, however the platform process list -v command tries to print it.
In this diff I'm adding the arguments as part of the packet, and now the command shows the arguments just like on mac.

On Mac:

62c9fe4273 uint32_t options -> File::OpenOptions options
Summary:
This patch re-types everywhere that passes a File::OpenOptions
as a uint32_t so it actually uses File::OpenOptions.

It also converts some OpenOptions related functions that fail
by returning 0 or NULL into llvm::Expected

split off from https://reviews.llvm.org/D68737

af1d27e301 [platform process list] add a flag for showing the processes of all users
Summary:
For context: https://reviews.llvm.org/D68293

We need a way to show all the processes on android regardless of the user id.
When you run `platform process list`, you only see the processes with the same user as the user that launched lldb-server. However, it's quite useful to see all the processes, though, and it will lay a foundation for full apk debugging support from lldb.

Before:
```
PID    PARENT USER       TRIPLE                   NAME
====== ====== ========== ======================== ============================
3234   1                 aarch64-unknown-linux-android adbd
8034   3234              aarch64-unknown-linux-android sh
9096   3234              aarch64-unknown-linux-android sh
9098   9096              aarch64-unknown-linux-android lldb-server
(lldb) ^D
```

Now:
```
(lldb) platform process list -x
205 matching processes were found on "remote-android"
PID    PARENT USER       TRIPLE                   NAME

696d3cf8ad [platform process list] add a flag for showing the processes of all users
Summary:
For context: https://reviews.llvm.org/D68293

We need a way to show all the processes on android regardless of the user id.
When you run `platform process list`, you only see the processes with the same user as the user that launched lldb-server. However, it's quite useful to see all the processes, though, and it will lay a foundation for full apk debugging support from lldb.

Before:
```
PID    PARENT USER       TRIPLE                   NAME

ecd849ed56 Fix a use-after-free in GDBRemoteCommunicationServerLLGS
Although it's called "GetString", StreamString::GetString actually
returns a StringRef. Creating a json object with a StringRef does not
make a copy, which means the StringRef will be dangling as soon as the
underlying stream is destroyed. Add a .str() to force the json object to
hold a copy of the string.

This fixes nearly every test on linux.

f913fd6eb0 factor out an abstract base class for File
Summary:
This patch factors out File as an abstract base
class and moves most of its actual functionality into
a subclass called NativeFile.   In the next patch,
I'm going to be adding subclasses of File that
don't necessarily have any connection to actual OS files,
so they will not inherit from NativeFile.

2fce1137c7 Convert FileSystem::Open() to return Expected<FileUP>
Summary:
This patch converts FileSystem::Open from this prototype:

Status
Open(File &File, const FileSpec &file_spec, ...);

to this one:

llvm::Expected<std::unique_ptr<File>>
Open(const FileSpec &file_spec, ...);

This is beneficial on its own, as llvm::Expected is a more modern
and recommended error type than Status.  It is also a necessary step
towards https://reviews.llvm.org/D67891, and further developments
for lldb_private::File.

948786c929 File::SetDescriptor() should require options
lvm_private::File::GetStream() can fail if m_options == 0

It's not clear from the header a File created with a descriptor will be
not be usable by many parts of LLDB unless SetOptions is also called,
but it is.

This is because those parts of LLDB rely on GetStream() to use the
file, and that in turn relies on calling fdopen on the descriptor. When
calling fdopen, GetStream relies on m_options to determine the access
mode. If m_options has never been set, GetStream() will fail.

This patch adds options as a required argument to File::SetDescriptor
and the corresponding constructor.

bcc24e46ba [Reproducer] Move GDB Remote Provider into Reproducer (NFC)
Originally the idea was for providers to be defined close to where they
are used. While this helped designing the providers in such a way that
they don't depend on each other, it also means that it's not possible to
access them from a central place. This proved to be a problem for some
providers and resulted in them living in the reproducer class.

The ProcessGDBRemote provider is the last remaining exception. This
patch makes things consistent and moves it into the reproducer like the

When the replay server is out of packets we should just disconnect so
the debugger doesn't have to do any cleanup that it wouldn't do during
capture.

d35b42f20a [NFC] Return llvm::StringRef from StringExtractor::GetStringRef.
This patch removes the two variant of StringExtractor::GetStringRef that
return (non-)const references to std::string. The non-const one was
being abused to reinitialize the StringExtractor and its uses are
replaced by calls to the copy asignment operator. The const variant was
refactored to return an actual llvm::StringRef.

6a253d378b [lldb] Qualify includes of Properties[Enum].inc files. NFC
Summary:
This is a bit more explicit, and makes it possible to build LLDB without
varying the -I lines per-directory.
(The latter is useful because many build systems only allow this to be
configured per-library, and LLDB is insufficiently layered to be split into
multiple libraries on stricter build systems).

(My comment on D65185 has some more context)

a8ea595509 [lldb] Also include the array definition in Properties.inc
Right now our Properties.inc only generates the initializer for the
options list but not the array declaration boilerplate around it. As the
array definition is identical for all arrays, we might as well also let
the Properties.inc generate it alongside the initializers.

Unfortunately we cannot do the same for enums, as there's this magic
ePropertyExperimental, which needs to come at the end to be interpreted
correctly. Hopefully we can get rid of this in the future and do the
same for the property enums.

971f9ca612 Let tablegen generate property definitions
Property definitions are currently defined in a PropertyDefinition array
and have a corresponding enum to index in this array. Unfortunately this
is quite error prone. Indeed, just today we found an incorrect merge
where a discrepancy between the order of the enum values and their
definition caused the test suite to fail spectacularly.

Tablegen can streamline the process of generating the property
definition table while at the same time guaranteeing that the enums stay
in sync. That's exactly what this patch does. It adds a new tablegen
file for the properties, building on top of the infrastructure that
Raphael added recently for the command options. It also introduces two
new tablegen backends: one for the property definitions and one for
their corresponding enums.

It might be worth mentioning that I generated most of the tablegen
definitions from the existing property definitions, by adding a dump
method to the struct. This seems both more efficient and less error
prone that copying everything over by hand. Only Enum properties needed
manual fixup for the EnumValues and DefaultEnumValue fields.

d668260f1a Correctly use GetLoadedModuleList to take advantage of libraries-svr4
Summary:
Here's a replacement for D62504. I thought I could use LoadModules to implement this but in reality I can't because there are at few issues with it:
* The LoadModules assumes that the list returned by GetLoadedModuleList is comprehensive in the sense that reflects all the mapped segments, however, this is not true, for instance VDSO entry is not there since it's loaded manually by LoadVDSO using GetMemoryRegionInfo and it doesn't represent a specific shared object in disk. Because of this LoadModules will unload the VDSO module.
* The loader (interpreter) module might have also been loaded using GetMemoryRegionInfo, this is true when we launch the process and the rendezvous structure is not yet available (done through LoadInterpreterModule()). The problem here is that this entry will point to the same file name as the one found in /proc/pid/maps, however, when we read the same module from the r_debug.link_map structure it might be under a different name. This is true at least on CentOS where the loader is a symlink. Because of this LoadModules will unload and load the module in a way where the rendezvous breakpoint is unresolved but not resolved again (because we add the new module first and remove the old one after).

The symlink issue might be fixable by first unloading the old and loading the news (but sounds super brittle), however, I'm not sure how to fix the VDSO issue.
Since I can't trust it I'm just going to use GetLoadedModuleList directly with the same logic that we use today for when we read the linked list in lldb. The only safe thing to do here is to only calculate differences between different snapshots of the svr4 packet itself. This will also cut the dependency this plugin has from LoadModules.

I separated the 2 logics into 2 different functions (remote and not remote) because I don't like mixing 2 different logics in the same function with if/else's. Two different functions makes it easier to reason with I believe. However, I did abstract away the logic that decides if we should take a snapshot or add/remove modules so both functions could reuse it.

The other difference between the two is that on the UpdateSOEntriesFromRemote I take the snapshot only once when state = Consistent because I didn't find a good reason to always update that, as we already got the list from state = Add | Remove. I probably should use the same logic on UpdateSOEntries though I don't see a reason not to since it's really using the same data, just read in different places. Any thoughts here?

It might also be worthwhile to add a test to make sure we don't unload modules that were not actually "unloaded" like the vdso. I haven't done this yet though.
This diff is also missing the option for svr4 like proposed in https://reviews.llvm.org/D62503#1564296, I'll start working on this but wanted to have this up first.

63e5fb76ec [Logging] Replace Log::Printf with LLDB_LOG macro (NFC)
This patch replaces explicit calls to log::Printf with the new LLDB_LOGF
macro. The macro is similar to LLDB_LOG but supports printf-style format
strings, instead of formatv-style format strings.

So instead of writing:

  if (log)
    log->Printf("%s\n", str);

You'd write:

  LLDB_LOG(log, "%s\n", str);

This change was done mechanically with the command below. I replaced the
spurious if-checks with vim, since I know how to do multi-line
replacements with it.

  find . -type f -name '*.cpp' -exec \
  sed -i '' -E 's/log->Printf\(/LLDB_LOGF\(log, /g' "{}" +
