This imports Chromium's `make_dafsa.py` script [1]. It takes in a gperf
formatted file (note: gperf is *not* required) and converts that to a compact
binary representation of the string data in the form of a deterministic
acyclic finite state automaton (DAFSA) [2].
The only change made to the script was to make it handle the arguments our
file generation script passes in to the `main` function.
It also imports the logic for traversing the DAFSA [3] almost verbatim in
`Dafsa.cpp`. A thin wrapper was added so that we can reuse the DAFSA structure
for multiple tables.
The only change made to the original logic was to swap in mozilla style
assertions and rename the not found constant from `kNotFound` to
`Dafsa::kKeyNotFound` in order to avoid a collision with `kNotFound` defined in
our nsString code.

This patch replaces four functions of the name AssignWithConversion which
are essentially wrappers around CopyASCIItoUTF16 and LossyCopyUTF16toASCII
with direct calls to the latter two functions. The replaced functions are:
void nsCString::AssignWithConversion( const nsAString& aData )
void nsString::AssignWithConversion( const nsACString& aData )
void nsTString_CharT::AssignWithConversion(
const incompatible_char_type* aData,
int32_t aLength = -1);
The last of the three exists inside the double-included nsTString* world and
so describes two functions, giving four in total.
This has two advantages:
* it removes code
* at the call points, it makes clear (from the replacement name) which
conversion is being carried out. The generic name "AssignWithConversion"
doesn't make that obvious -- one had to infer it from the types.
The patch also removes two commented out lines from
editor/composer/nsComposerCommands.cpp, that appear to be related. They are
at top level, where they would never have compiled. They look like
leftovers from some previous change.

A number of places in JS need to drain the current thread's event queue,
which cannot be done with nsIThreadManager::spinEventLoopUntil, since we
need to not wait for an incoming event when attempting to process one.
This is a preexisting issue that makes nsMultiplexInputStream multiple-inherit
from nsIInputStream: once via nsIMultipartInputStream and once via
nsIAsyncInputStream. This causes problems once we end up with more multiplex
streams that are async streams, because then some assingments to
nsCOMPtr<nsIInputStream> start asserting. This patch just removes the footgun
by getting rid of the multiple inheritance.
This modifies the logic in |CheckAcquisition| to only call |NS_ERROR| if we're
really going to deadlock. Instead, if we detect a suspicious cycle, we just use
an |NS_WARNING|. This means that we'll still output warning text in debug
builds, but we won't cause the process to abort.

See also bug 1361495 - PR_SI_HOSTNAME is implemented in NSPR on
Windows as initializing winsock which can be janky. There don't seem
to be any users of this property, and it has tracker concerns anyhow -
so remove it.

Change mozilla::Smprintf and friends to return a UniquePtr, rather than
relying on manual memory management. (Though after this patch there are
still a handful of spots needing SmprintfFree.)

This adds an arena allocator that can be used as a drop-in replacement for
NSPR's PLArena. Example usage for defining an 8-byte aligned allocator that
uses a 4K arena size:
mozilla::ArenaAllocator<4096,8> a;
void* memory = a.Allocate(200);
There's an antipattern where nsLiteralString is used as an unnecessary intermediary in converting from CharT* to CharT*,
e.g. CallAFunctionThatTakesACharPointer(NS_LITERAL_CSTRING("foo").get());
or
NS_NAMED_LITERAL_STRING(foo, "abc");
CallAFunctionThatTakesACharPointer(foo.get());
This patch rewrites the callsites that can be trivially changed to use char*/char16_t*.
I'd somewhat like to remove nsTLiteralString::get() altogether, but in code that's less straightforward than these examples, get() is useful enough to keep.

This just-so-happened to work because nobody refers to the splitter directly by name.
The added gtest doesn't actually prove that this patch fixes anything, but I figured we could use a wide string for good measure.

Handling potential nsDeque size changes means a bit of extra work.
But if the nsDeque is const, we can assume that it shouldn't get modified, so
we can provide a more optimized iterator that doesn't need to handle size
changes.
Optimizing a range-for loop in which the deque is not modified, can be done
by writing: `for (void* item : const_cast<const nsDeque&>(deque)) {...}`

Note that iterators stay at the same index if the deque size changes
(including end-iterators staying at the end).
This means that after front operations, iterators will effectively point at
different elements! (Possibly skipping or re-visiting some.)
But this is consistent with ForEach and hand-crafted index-based for loops.

There are several XPCOM tests that purport to call
NS_RegisterStaticAtoms. The tests located in the xpcom/tests/ directory
are unused, so we might as well just remove them. The gtests do get
run, but there's going to be no way to test NS_RegisterStaticAtoms once
sealing the atom table actually means forbidding new additions. So we
might as well remove the gtest too.
This change is mostly straightforward, except for the following.
- It removes all the printing from the do_check_* macros because gtest macros
do appropriate printing.
- test_StatementCache.cpp needs some special gtest magic for the type
parameterization.
- It merges the four tests in test_unlock_notify.cpp because they rely on being
executed in order, and so aren't independent.
- storage_test_harness_tail.h is no longer necessary because gtest provides the
test looping functionality.
- It uses #include and the preprocessor to remove the duplication between
test_deadlock_detector.cpp and xpcom/tests/DeadlockDetector.cpp.
- It makes the test in test_service_init_background_thread.cpp a death test to
force it to be the first storage gtest, because it fails otherwise.
- It adds code to undo the SQLite mutex hooking as necessary, so that tests
don't interfere with each other.
- It de-virtualizes Spinner's destructor (as identified in bug 1318282).

This converts the tests to gtests. Most of them are just runtime tests and just

it's still built-in. You can run the disabled test with the following command:

This converts TestDeadlockDetector to a gtest. The logic for spawning off
subprocesses is replaced with gtest's built-in death tests. On linux this will
clone() the process and assert that the child process generates the appropriate

Windows as well buy spawning a new process but this test currently disabled
