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.

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.

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.

The test helper_touch_action_regions.html uses nsDOMWindowUtils to synthesize native input events and creates some runnables to trigger the test. It expects the runnables which synthesize native input events are processed first, then the runnables to continue the test, and finally the input events are forwarded from chrome process to content process. Enabling event prioritization may change the execution order.
Wraps those runnables to synthesize native input events as priority=input and dispatches those runnables to continue the test with priority=input to make sure the execution order is as expected.

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.

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.

These will be used to implement IPC serialization and deserialization of the

I actually couldn't figure out a way to trigger this assertion with the
current string code without doing invalid casts, but there are things we
may want to add to the string code in the future that might risk hitting
this (e.g., move constructors, promoting various rebind methods to
nsA[C]String), so I think it's worth asserting.

The simplistic shift-based hashing function creates a lot of collisions
for pointers pointing to arrays as it doesn't do a great job at distributing
the data randomly based on the input bytes.
Running with XPCOM_MEM_LOG_CLASSES=nsStringBuffer triggers an
assertion in refcount logging for nsFakeStringBuffers. These are given
an initial refcount of 1, without calling NS_LOG_ADDREF. Then,
AddRef() is called on these objects in StaticAtom::StaticAtom(), and
we tell the refcount logging system about the fake buffer, and that it
has a refcount of 0, triggering the assertion.
The first part of the fix is to call NS_LOG_ADDREF for this initial
refcount, in StaticAtom().
This first fix causes refcount logging to start reporting that the
fake string buffers leak, when XPCOM_MEM_LOG_CLASSES is not set. This
is because refcount logging is now getting told about these objects
being AddRefed at 1, which it takes to mean that an object is created.
To work around this issue, I add an array gFakeBuffers that contains
every fake string buffer we create, and tell the refcount logging
system that these objects are all being destroyed, when the atom table
is being shut down. This could result in some bogosity if the fake
buffers are "leaked" but hopefully this is still an improvement over
the current state.
