bug that we run out of TLS slots on Windows is no longer showing up after
firefox55. It should have been fixed elsewhere, very likely in the rust part.

The existing functions work with C strings but almost all the call sites use
Mozilla strings.
The replacement function has the following properties.
- It works with Mozilla strings, which makes it much simpler and also improves
the call sites.
- It appends to the destination string because that's what a lot of the call
sites need. For those that don't, we can just append to an empty string.
- It is declared outside the |extern "C"| section because there is no need for
it to be in that section.
Note: there is no 16-bit variant of nsAppendEscapedHTML(). This is because
there are only two places that need 16-bit variants, both rarely executed,
and so converting to and from 8-bit is good enough.
The patch also adds some testing of the new function, renaming
TestEscapeURL.cpp as TestEscape.cpp in the process, because that file is now
testing other kinds of escaping.

The --track flag provides a more accurate accounting of what files were
installed by the manifest, so they can be appropriately removed. For
example, test files are now removed from _tests if an entry in a test
file is deleted.
The --no-remove flag is removed as an alternative, and the --track flag
is now mandatory.

This patch refactors the nsThread event queue to clean it up and to make it easier to restructure. The fundamental concepts are as follows:
Each nsThread will have a pointer to a refcounted SynchronizedEventQueue. A SynchronizedEQ takes care of doing the locking and condition variable work when posting and popping events. For the actual storage of events, it delegates to an AbstractEventQueue data structure. It keeps a UniquePtr to the AbstractEventQueue that it uses for storage.
Both SynchronizedEQ and AbstractEventQueue are abstract classes. There is only one concrete implementation of SynchronizedEQ in this patch, which is called ThreadEventQueue. ThreadEventQueue uses locks and condition variables to post and pop events the same way nsThread does. It also encapsulates the functionality that DOM workers need to implement their special event loops (PushEventQueue and PopEventQueue). In later Quantum DOM work, I plan to have another SynchronizedEQ implementation for the main thread, called SchedulerEventQueue. It will have special code for the cooperatively scheduling threads in Quantum DOM.
There are two concrete implementations of AbstractEventQueue in this patch: EventQueue and PrioritizedEventQueue. EventQueue replaces the old nsEventQueue. The other AbstractEventQueue implementation is PrioritizedEventQueue, which uses multiple queues for different event priorities.
The final major piece here is ThreadEventTarget, which splits some of the code for posting events out of nsThread. Eventually, my plan is for multiple cooperatively scheduled nsThreads to be able to share a ThreadEventTarget. In this patch, though, each nsThread has its own ThreadEventTarget. The class's purpose is just to collect some related code together.
One final note: I tried to avoid virtual dispatch overhead as much as possible. Calls to SynchronizedEQ methods do use virtual dispatch, since I plan to use different implementations for different threads with Quantum DOM. But all the calls to EventQueue methods should be non-virtual. Although the methods are declared virtual, all the classes used are final and the concrete classes involved should all be known through templatization.

HangAnnotations was very complex, required a separate allocation, and used this
unfortunate virtual interface implementation which made it harder to do
interesting things with it (such as serialize it over IPC).
This new implementation is much simpler and more concrete, making
HangAnnotations simply be a nsTArray<Annotation>. This also simplifies some of
the IPC code which was added in part 7.

This function takes up quite a bit of space, and there's no need to for
the log getter to be inlined everywhere. Moving this to out-of-line
code saves ~200K on x86-64 Linux.
These are all easy cases where an nsXPIDLCString local variable is set via
getter_Copies() and then is used in ways that rely on the implicit conversion
to |char*|. The patch uses get() and EqualsLiteral() calls to replace the
implicit conversions.
The current definition of MOZ_LOG requires calling
LazyLogModule::operator() multiple times, which is unnecessary. We can
avoid that with a bit of clever macro definition and a lengthy
explanation.
I went with the simplest possible approach here, and only added support for
"locale" and "override" entries, since we don't expect this to stick around
very long.

In all of these cases the fixed buffer has the same lifetime as the string
object, so we can use nsAuto[C]String for simplicity.
For the 128-length ones in dom/xul/ I just switched to the default of 64 for
simplicity, because the choice of 128 didn't seem that important. (These code
paths weren't hit when I started the browser and opened a few sites.)
Finally, the patch also changes LoggingIdString to use
nsAutoCStringN<NSID_LENGTH>, similar to NullPrincipalURI.
This patch parameterizes nsAuto[C]String, renames them as nsAuto[C]StringN, and
redefines nsAuto[C]String as typedefs for nsAuto[C]StringN<64>.
(The alternative would be to templatize nsAuto[C]String and use a default
parameter, but that would require writing "nsAuto[C]String<>" everywhere.)
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 is mainly to make IdleTaskRunner reusable by nsHtml5TreeOpExecutor.
The only necessary work to that purpose is to remove the dependency of
sShuttingDown, which was a static variable in nsJSEnvironment.cpp.
The idea is to have a "MayStopProcessing" as a callback for the consumer to
return sShuttingDown.
In addition to sShuttingDown, we use std::function<bool()> as the runner
main callback type.

XPIDL generated header files contain a |#if 0| block for every interface,
providing the skeleton of the class as it must be implemented in C++. This is
potentially useful, but also very verbose.
This patch removes this code. In a Linux64 debug build, this reduces the total
size of the $OBJDIR/dist/include/nsI*.h files from 11,023,499 bytes to
8,442,350 bytes, a 23.5% reduction. It didn't speed up compilation, though.

nsTArray::AppendElement{,s} uses an IncrementLength method to adjust the
length of the array after appending elements. There are checks in
IncrementLength to ensure that we're not incrementing the length stored
in the static empty header object; these checks are necessary in cases
such as appending a zero-length array to another zero-length array.
But we do not need this check when we're calling AppendElement: we know
the header is obviously not the empty header, because we increased the
length of the array by one for the newly appended element. Incrementing
the length can therefore be inlined, saving ~90K of codesize on x86-64
Linux.
MozStackWalk() is different on Windows to the other platforms. It has two extra
arguments, which can be used to walk the stack of a different thread.
This patch makes those differences clearer. Instead of having a single function
and forbidding those two arguments on non-Windows, it removes those arguments
from MozStackWalk, and splits off MozStackWalkThread() which retains them. This
also allows those arguments to have more appropriate types (HANDLE instead of
uintptr_t; CONTEXT* instead of than void*) and names (aContext instead of
aPlatformData).
The patch also removes unnecessary reinterpret_casts for the aClosure argument
at a couple of MozStackWalk() callsites.

All the SizeOf{In,Ex}cludingThis() functions take a MallocSizeOf function
which measures memory blocks. This patch introduces a new type, SizeOfState,
which includes a MallocSizeOf function *and* a table of already-measured
pointers, called SeenPtrs. This gives us a general mechanism to measure
graph-like data structures, by recording which nodes have already been
measured. (This approach is used in a number of existing reporters, but not in
a uniform fashion.)
The patch also converts the window memory reporting to use SizeOfState in a lot
of places, all the way through to the measurement of Elements. This is a
precursor for bug 1383977 which will measure Stylo elements, which involve
Arcs.
The patch also converts the existing mAlreadyMeasuredOrphanTrees table in the
OrphanReporter to use the new mechanism.

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.
