d2a866978b Makes 'all' build on Linux
I can never remember which targets are buildable; this makes just

  ninja -C out/lin

work, without too much fuss. I think this means we could turn on trybots
too, as I think all the tests that are built also run.

281be63d00 Standardize on static constexpr for arrays when possible
This uses “static” at function scope to avoid making local copies, even
in cases where the compiler can’t see that the local copy is
unnecessary. “constexpr” adds additional safety in that it prevents
global state from being initialized from any runtime dependencies, which
would be undesirable.

At namespace scope, “constexpr” is also used where appropriate.

For the most part, this was a mechanical transformation for things
matching '(^| )const [^=]*\['.

Similar transformations could be applied to non-arrays in some cases,
but there’s limited practical impact in most non-array cases relative to
arrays, there are far more use sites, and much more manual intervention
would be required.

b8aaa22905 mac handler: Record a file-limits annotation (temporarily)
The "file-limit" annotation will be used to confirm the theory that
certain crashes are caused by systems at or near their file descriptor
table size limits.

The annotation records the system-wide kern.num_files and kern.maxfiles
values, and the process-specific current and maximum file descriptor
limits.

The annotation will be set on crashpad_handler startup, and will be
refreshed every time an exception is handled and every time the upload
thread processes a pending report.

It’s expected that this annotation will be removed after enough data has
been collected to confirm the theory. However, the principle is useful
enough that we may want to provide this feature more generally under
bugs 19 or 21.

8297b19a5e Don’t attempt to do periodic tasks in a secondary crashpad_handler
76a67a37b1d0 adds crashpad_handler’s --monitor-self argument, which
results in a second crashpad_handler instance running out of the same
database as the initial crashpad_handler instance that it monitors. The
two handlers start at nearly the same time, and will initially be on
precisely the same schedule for periodic tasks such as scanning for new
reports to upload and pruning the database. This is an unnecessary
duplication of effort.

This adds a new --no-periodic-tasks argument to crashpad_handler. When
the first instance of crashpad_handler starts a second to monitor it, it
will use this argument, which prevents the second instance from
performing these tasks.

When --no-periodic-tasks is in effect, crashpad_handler will still be
able to upload crash reports that it knows about by virtue of having
written them itself, but it will not scan the database for other pending
reports to upload.

76a67a37b1 Add the --monitor-self argument to crashpad_handler
https://crbug.com/678959 added “fallback” crash reporting for
crashpad_handler on Windows, in a Chrome- and Windows-specific way. This
implements a more general self-monitor mechanism that will work on
multiple platforms and in the absence of Chrome.

When starting crashpad_handler (let’s call it the “first instance”) with
--monitor-self, it will start another crashpad_handler (the “second
instance”). The second instance monitors the first one for crashes. The
second instance will be started in mostly the same way as the first
instance, except --monitor-self will not be provided to the second
instance.

0c322ecc3f Use zlib to gzip-compress uploads
This adds zlib to Crashpad. By default in standalone Crashpad builds,
the system zlib will be used where available. A copy of Chromium’s zlib
(currently a slightly patched 1.2.11) is checked out via DEPS into
third_party for use on Windows, which does not have a system zlib.

zlib is used to produce gzip streams for HTTP upload request bodies sent
by crashpad_handler by default. The Content-Encoding: gzip header is set
for these compressed request bodies. Compression can be disabled for
upload to servers without corresponding decompression support by
starting crashpad_handler with the --no-upload-gzip option.

Most minidumps compress quite well with zlib. A size reduction of 90% is
not uncommon.

948fd2d019 mac: Report a metric for handler crashes
This installs signal handlers in the crashpad_handler process to log
these crashes via the Crashpad.HandlerCrash.ExceptionCode.Mac histogram.
This is roughly the same mechanism that’s used for Windows.

The signal handler tries fairly hard to avoid swallowing signals, so
that things appear to outside observers (including debuggers and crash
handlers) identically to how they would look if no signal handler was
present.

The signal handler uses a different mapping schema than the existing
Crashpad.ExceptionCode.Mac histogram for reasons explained in code
comments. Because the mappings should not overlap, the new values may be
added to the existing CrashpadMacExceptionCodes enum.

2d87606bb5 win: Start crashpad_handler by inheriting connection data to it
Previously, StartHandler() launched the handler process, then connected
over a pipe to register for crash handling. Instead, the initial client
can create and inherit handles to the handler and pass those handle
values and other data (addresses, etc.) on the command line.

This should improve startup time as there's no need to synchronize with
the process at startup, and allows avoiding a call to CreateProcess()
directly in StartHandler(), which is important for registration for
crash reporting from DllMain().

Incidentally adds new utility functions for string/number conversion and
string splitting.

Note: API change; UseHandler() is removed for all platforms.

change is similar to that one, except more care was taken to avoid
