1. The unsetting of LD_LIBRARY_PATH is removed, because it's no longer
necessary and interferes with environments where it's necessary to find
"system" libraries like GTK; see bug 1472589 comment #1 through #4.
2. The Snap package manifest adds a dependency on the libcurl package,
so that the crash reporter can send the report. This uses the GnuTLS
variant because we're already pulling in GnuTLS as a dependency of some
other packages (FFmpeg and CUPS, but also the non-GnuTLS cURL packages
depend on it anyway via OpenLDAP).

Because the .xdata format on ARM64 can only encode sizes up to 1M (much too small for our JIT code regions), we register a function table callback to provide RUNTIME_FUNCTIONs at runtime. Windows doesn't seem to care about the size fields on RUNTIME_FUNCTIONs that are created in this way, so the same RUNTIME_FUNCTION can work for any address in the region. We'll set up a generic one in RegisterExecutableMemory and the callback can just return a pointer to it.

But keep the crashreporter disabled at runtime because it doesn't work
yet.
This has the side effect of creating the artifacts with the
crashreporter symbols and pdbs.

Previously, our panic hook was only really useful when the crash
reporter is used, because all it did apart from calling rust's default
panic handler was to keep a pointer to the panic message for the crash
reporter.
Now that it just redirects to the Gecko crash code, it doesn't need to
be tied to the crash reporter. In fact, to ensure it's consistently used
in all cases, we ought to install it early on. Use a static initializer
for that.

The current rust panic hook keeps a string for the crash reporter, and
goes on calling the default rust panic hook, which prints out a crash
stack... when RUST_BOOTSTRAP is set *and* when that works. Notably, on
both mac and Windows, it only really works for local builds, but fails
for debug builds from automation, although on automation itself, we also
do stackwalk from crash minidumps, which alleviates the problem.
Artifact debug builds are affected, though.
More importantly, C++ calls to e.g. MOZ_CRASH have a similar but
different behavior, in that they dump a stack trace on debug builds, by
default (with exceptions, see below for one). The format of those stack
traces is understood by the various fix*stack*py scripts under
tools/rb/, that are used by the various test harnesses both on
automation and locally.
Additionally, the current rust panic hook, as it calls the default rust
panic hook, ends up calling abort() on non-Windows platforms, which ends
up being verbosely redirected to mozalloc_abort per
https://dxr.mozilla.org/mozilla-central/rev/237e4c0633fda8e227b2ab3ab57e417c980a2811/memory/mozalloc/mozalloc_abort.cpp#79
which then calls MOZ_CRASH. Theoretically, /that/ would also print a
stack trace, but doesn't because currently the stack trace printing code
lives in libxul, and MOZ_CRASH only calls it when compiled from
libxul-code, which mozalloc_abort is not part of.
With this change, we make the rust panic handler call back into
MOZ_CRASH directly. This has multiple advantages:
- This is more consistent cross-platforms (Windows is not special
anymore).
- This is more consistent between C++ and rust (stack traces all look
the same, and can all be post-processed by fix*stack*py if need be)
- This is more consistent in behavior, where debug builds will show
those stack traces without caring about environment variables.
- It demangles C++ symbols in rust-initiated stack traces (for some
reason that didn't happen with the rust panic handler)
A few downsides:
- the loss of demangling for some rust symbols.
- the loss of addresses in the stacks, although they're not entirely
useful
- extra empty lines.
The first should be fixable later one. The latter two are arguably
something that should be consistent across C++ and rust, and should be
changed if necessary, independently of this patch.

This reverts the changes in bug 1360308, bug 1390143 and bug 1469603. Minidump
generation will now only happen on the main process' main thread which might
lead to hangs but is known to be fairly robust. Asynchronous generation proved
too brittle and enormously increased the complexity of this already
hard-to-read code.

In order to implement profile-per-install we need a mutable INI parser in early
startup. The current one is implemented in JavaScript and thus not available.
This makes the current read-only C++ INI parser mutable and removes the
JavaScript implementation.
It turns out that the two different implementations of nsIINIParserFactory and
nsIINIParser behaved slightly differently but only in ways that the single test
cared about so I've adjusted things a little to make it work.
The existing C++ implementation did not do validity checks on arguments, this
adds that making empty sections and values illegal.

This introduces the machinery needed to generate crash annotations from a YAML
file. The relevant C++ functions are updated to take a typed enum. JavaScript
calls are unaffected but they will throw if the string argument does not
correspond to one of the known entries in the C++ enum. The existing whitelists
and blacklists of annotations are also generated from the YAML file and all
duplicate code related to them has been consolidated. Once written out to the
.extra file the annotations are converted in string form and are no different
than the existing ones.
All existing annotations have been included in the list (and some obsolete ones
have been removed) and all call sites have been updated including tests where
appropriate.
Use the fact that a JobIntentService is still a Service to keep most of the
previous implementation and method of starting CrashReportingService.
On 26+ devices it will be called with "start-foreground-service".
This ensures it can be started even from background and the crash reporting
process would work as before but ActivityManager will post an ANR error to
logcat after 5 seconds because we aren't calling Service.startForeground()
(which would mean a user visible notification).
Will use different Job Ids depending on if the app is Firefox Release or
Firefox Beta.
The Job Id will be passed to GeckoThread when first initializing and then be
made available to CrashHandler and nsExceptionHandler.cpp to be sent in the
Intent that starts the CrashReporterService.

Bug 1458161 added a rust OOM handler based on an unstable API that was
removed in 1.27, replaced with something that didn't allow to get the
failed allocation size.
Latest 1.28 nightly (2018-06-13) has
https://github.com/rust-lang/rust/pull/50880,
https://github.com/rust-lang/rust/pull/51264 and
https://github.com/rust-lang/rust/pull/51241 merged, which allow to
hook the OOM handler and get the failed allocation size again.
Because this is still an unstable API, we explicitly depend on strict
versions of rustc. We also explicitly error out if automation builds
end up using a rustc version that doesn't allow us to get the allocation
size for rust OOM, because we don't want that to happen without knowing.
