This change surfaces errors faster, and ensures that we don't silently
end up with empty crashreporter symbols if `dump_syms` can't run for
some reason.

With the removal of the old Chromium file_util code, we should no longer
be using temporary files with names starting with "org.chromium.", so the
crash reporter and main thread I/O test no longer need to recognize that
prefix.

This changes the way crash reports for child processes happening too early
during the child process' startup. Before bug 1547698 we wrote a partial
.extra file with those crashes that lacked the process type. The user would
not be notified of those crashes until she restarted Firefox and even when
submitted those crashes would be erroneously labeled as browser crashes.
After bug 1547698 we stopped writing .extra files entirely for those crashes
which left orphaned .dmp files among the pending crash reports.
This patch does three things to improve the situation:
* It writes a partial .extra file so that the crashes are detected at the next
startup. So the user is still not notified directly of these crashes but she
can report them later.
* It adds the process type to the .extra file so that the crash reporters are
labelled correctly.
* It fixes a leak in the `pidToMinidump` hash-map. Since the crashes were
not finalized the `ChildProcessData` strucutre associated with them would
never be fred.

The most important part is the `GetPHCAddrInfo()` function in
`exception_handler.cc`, which extracts a crash address from an
`EXCEPTION_POINTERS` object.
The commit also changes the code so that it works if MozStackWalk() returns an
empty stack trace. This happens in practice on Windows on automation sometimes,
I'm not sure why.
The rest of the commit is just plumbing and the smoothing over of minor
platform differences.

This uses GetPerformanceInformation() to measure how much commit space is
available globally. Previously we relied on GlobalMemoryStatusEx() but in
spite of the function name the commit-space values it returns are
*per process* and thus unreliable. Available physical memory measurement has
also been removed since it was never used and we don't plan on using it
anytime soon.

This patch includes multiple changes cleaning up various aspects of the crash
reporter client and exception handler:
* Some Unix-specific code was moved out from the base crashreporter client
code and into the appropriate platform implementation
* Functions used to open files in the crashreporter client now accept C++
`std::ios` flags instead of unreadable booleans
* Useless character conversion routines were removed from the
minidump-analyzer
* Crash annotations are not serialized into a huge string anymore every time
they change. They are all written out individually during an exception.
* `WriteEscapedMozCrashReason()` uses the exception-safe `my_strlen()` instead
of plain `strlen()`
* The Windows-specific DLL-blocklist shutdown was removed from the Linux &
macOS Breakpad callbacks
* The `CrashReporterHost`, `CrashReporterClient` and
`CrashReporterMetadataShmem` classes now take `nsACString` references
instead of `nsCString` ones since they never modify their contents

Annotation on main process crashes are written to both the .extra file
(for crash submission) and to the event file so that the browser can
detect the crash when restarting even if the crash report files have
been deleted.
This patch factorizes all the code that writes to both files, cutting
down all the duplicate calls, and fixes an issue with the
BreakpadReserveAddress and BreakpadReserveSize annotations which were
not written to the event file.

Upon a content process crash or hang crash annotations were incrementally
written into the .extra file starting with the exception handler callback and
then in a number of different places before the file was ready for submission.
This had a number of downsides: since the annotations were directly added to
the file it was impossible to tell which ones were already written at a
certain point in time, additionally some were written twice or even thrice.
The code doing the writing would also behave differently depending on the
contents of the file, the parameters passed to it and the contents of global
variables.
This change overhauls the whole process by keeping the annotations into a
temporary per-crash annotation table which is filled with all the required
annotations before being written out in a single pass when they are ready.
The annotations are gathered from the main process annotation table, the
per-process one (held by the CrashReporterHost) and exception-time specific
ones.
The resulting annotations are slightly different than before the patch: first
of all there are no more duplicate entries in the .extra file and secondly all
content/plugin process hangs annotations are properly filtered, before
annotations that were main process-only would leak into them.

Expose the driver vendor information (applies to Linux only at this
moment) to crash report telemetry and about:support. This will be useful
when debugging issues to know specifically what driver is in use.
Also expose the monitor information for Linux. Part 1 provides an
implementation to get the monitor information on said platform.
