Now both profilers are controlled by the same environment variables, e.g.
"MOZ_PROFILER_STARTUP" to run both profilers at startup.
The only remaining Base Profiler-specific commands are:
- MOZ_BASE_PROFILER_HELP, because the Base Profiler doesn't have the same
capabilities as Gecko, so it may display different available features.
- MOZ_BASE_PROFILER_LOGGING, because the Base Profiler doesn't have access to
MOZ_LOG (both the env-var and the C++ macros).

If EAF+ is enabled for firefox.exe, the process does not launch because we parse
the PE headers of ntdll.dll at startup, which is prohibited by EAF+.
With this patch, we skip two operations when EAF+ is enabled.
The first one is to cache ntdll's IAT at startup. Because EAF+ is expected to
prevent an injected module from parsing PE headers and modifying IAT, we can skip
this caching safely.
The second one is to load ntdll's debug information for the profiler. With this
patch, the profiler's callstack will not show a raw address instead of a symbol
name. It's a bad side effect, but much better than startup crash.

This is the logic of tracing the WebGPU API calls at the level of wgpu-core,
serialized into a folder of choosing on the user drive. Traces are extremely portable,
they can be shared (on BugZilla) and then replayed on the developer machine,
which can have a different architecture from the users machine.
The standalone player is introduced in `gfx/wgpu/player`, similar to WebRender's Wrench.
The output dir is controlled by "dom.webgpu.traceDir" pref. No tracing happens if it's empty.

This code was not being built any more.
GeckoView requires Android OS version 4.3 (API Level 18). I'm not sure what the
corresponding ANDROID_VERSION macro constant for API Level 18 is, but it's
definitely higher than 16.

When the tracker is destroyed, any extant channel is closed, this can trigger the rejection of pending promises, which dispatch tasks to promise handlers. So we need to ensure that this happens before threads cannot service dispatches anymore.

In addition to the existing "mainthreadio" feature, we now have:
- "fileio" to also capture file I/O from other profiled threads.
- "fileioall" to also capture file I/O from all threads (even unregistered threads).
- "noiostacks" to prevent capturing stack traces for "io" markers.
These are all off by default, except for `MOZ_PROFILER_STARTUP=1`.

This can be used while the profiler is running, to know if the current thread is registered -- regardless of whether it is actively profiled.
This will help distinguish registered but non-profiled threads from threads that are not even registered (e.g., OS-generated threads).

Some functions may want to examine more than one feature at once, these function return everything (if the profiler is active, and optionally unpaused) so that only one call is needed.

This is a simple compile-time check that the feature numbers go from 0 to N-1, to prevent some mistakes when updating feature lists.

The FileIO marker may be recorded into the main thread, so we need to keep track of the thread in which the IO really happened (which may be a thread that's not even selected for profiling).
There is not JSON output for it yet.

Some markers may be more useful when gathered into a single track, and the main thread is ideal because it's almost always present.

I need to add symbolication support for the mochitest Gecko Profiler command line
option. These profiles also need to be symbolicated. Unfortunately, there is not
a common place where I could use these files. Talos and Raptor each had their
own copy of the snappy symbolication server.
This commit consolidates these packages into a re-usable mozbase package that can
be used in mochitests, and eventually in other places like xpcshell tests.
I stubbed out a test file, but it doesn't do anything quite yet. This commit makes
it so that the tests still work in Raptor and Talos, but doesn't add any features.
It also doesn't try too hard to make the files look like a mozbase package.

Instead of accepting a `UniquePtr<ProfilerMarkerPayload>`, `profiler_add_marker_for_thread` now takes it by `const ProfilerMarkerPayload&`.
All callers can now create the payload on the stack, or as a temporary object. This saves a memory alloc+free for each call.

This patch will do :
- add `Media` markers in related codes
- implement `MediaSampleMarkerPayload` to record the media sample
The advantage of doing so :
- using markers can help us know what happens on the media by a glance without expanding the call stack
- adding sample markers allows us compare the speed of decoding sample in `MediaDecoderStataMachine` and rendering sample in `VideoSink`

In some NT-specific code, a list of "items()" was being updated. In python 3, to modify the result
of "items()", you have to gain ownership first by explicitly converting it into a list().

We had to increase the java buffer limit to 64MiB because it was a bottleneck
and 8MiB wasn't enough for 1ms sampling rate. It was getting full pretty quick.
Even though we increased that limit, we are not going to allocate all of this
at the start. Since we are allocating the buffer chunk by chunk, we are going
to allocate only when we need.

If a label contains a dynamic string that's too long (512 characters or more), instead of just replacing it with "(too long)", we now cut it down to the maximum size, with an ellipsis at the end.
