c4a3395103 Fix a couple of corner cases in NameMatches
Summary:
I originally set out to move the NameMatches closer to the relevant
function and add some unit tests. However, in the process I've found a
couple of bugs in the implementation:
- the early exits where not always correct:
  - (test==pattern) does not mean the match will always suceed because
    of regular expressions
  - pattern.empty() does not mean the match will fail because the "" is
    a valid prefix of any string

So I cleaned up those and added some tests. The only tricky part here
was that regcomp() implementation on darwin did not recognise the empty
string as a regular expression and returned an REG_EMPTY error instead.
The simples fix here seemed to be to replace the empty expression with
an equivalent non-empty one.

5fb8af40df Refactor log channel registration mechanism
Summary:
We currently have two log channel registration mechanisms. One uses a
set of function pointers and the other one is based on the
PluginManager.

The PluginManager dependency is unfortunate, as logging
is also used in lldb-server, and the PluginManager pulls in a lot of
classes which are not used in lldb-server.

Both approach have the problem that they leave too much to do for the
user, and so the individual log channels end up reimplementing command
line argument parsing, category listing, etc.

Here, I replace the PluginManager-based approach with a one. The new API
is more declarative, so the user only needs to specify the list of list
of channels, their descriptions, etc., and all the common tasks like
enabling/disabling categories are hadled by common code. I migrate the
LogChannelDWARF (only user of the PluginManager method) to the new API.

In the follow-up commits I'll replace the other channels with something
similar.

6302bf6a26 Clean up debug logging
Summary:
We've had two ways to print a "debug" log message.
- Log::GetDebug() was testing a Stream flag which was never set.
- Log::Debug() was checking for the presence of "log enable --debug"
flag.

Given that these two were used very rarely and we already have a
different way to specify "I want a more verbose log", I propose to remove
these two functions and migrate the callers to LLDB_LOGV. This commit
does that.

a9e67df2f9 [cmake] add missing dependency lldbCommands->lldbBase
CommandObjectVersion.cpp calls lldb_private::GetVersion (present in lldbBase).

This should fix the unittest link on windows. I am not sure why is this not
present on other platforms -- my guess is that there lldbBase is included in
the link through some other dependency chain.

c5f28e2a05 Switch std::call_once to llvm::call_once
Summary:
The std::call_once implementation in libstdc++ has problems on few systems: NetBSD, OpenBSD and Linux PPC. LLVM ships with a homegrown implementation llvm::call_once to help on these platforms.

This change is required in the NetBSD LLDB port. std::call_once with libstdc++ results with crashing the debugger.

bf9a77305f Move classes from Core -> Utility.
This moves the following classes from Core -> Utility.

ConstString
Error
RegularExpression
Stream
StreamString

The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes.  So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

494f277af5 [CMake] Add accurate dependency specifications
Summary:
This patch adds accurate dependency specifications to the mail LLDB libraries and tools.

In all cases except lldb-server, these dependencies are added in addition to existing dependencies (making this low risk), and I performed some code cleanup along the way.

For lldb-server I've cleaned up the LLVM dependencies down to just the minimum actually required. This is more than lldb-server actually directly references, and I've left a todo in the code to clean that up.

4687db0e09 Provide a substitute to load command of gdb.
For bare-metal targets, lldb was missing a command like 'load' in gdb
which can be used to create executable image on the target. This was
discussed in
http://lists.llvm.org/pipermail/lldb-dev/2016-December/011752.html

This commits adds an option to "target module load" command to provide
that functionality. It does not set the PC to entry address which will
be done separately.

107d9bbd6c Add a more succinct logging syntax
This adds the LLDB_LOG macro, which enables one to write more succinct log
statements.
if (log)
  log->Printf("log something: %d", var);
becomes
LLDB_LOG(log, "log something: {0}, var);

The macro still internally does the "if(log)" dance, so the arguments are only
evaluated if logging is enabled, meaning it has the same overhead as the
previous syntax.

Additionally, the log statements will be automatically prefixed with the file
and function generating the log (if the corresponding new argument to the "log
enable" command is enabled), so one does not need to manually specify this in
the log statement.

It also uses the new llvm formatv syntax, which means we don't have to worry
about PRIx64 macros and similar, and we can log complex object (llvm::StringRef,
lldb_private::Error, ...) more easily.

enumeration.  There are a lot of callsites, though, so the
changes will be done incrementally, starting with this one.

31d97a5c8a Rewrite all Property related functions in terms of StringRef.
This was a bit tricky, especially for things like
OptionValueArray and OptionValueDictionary since they do some
funky string parsing.  Rather than try to re-write line-by-line
I tried to make the StringRef usage idiomatic, even though
it meant often re-writing from scratch large blocks of code
in a different way while keeping true to the original intent.

The finished code is a big improvement though, and often much
shorter than the original code.  All tests and unit tests
pass on Windows and Linux.

c156427ded Don't allow direct access to StreamString's internal buffer.
This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.

Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.
