On iOS, holding a lock during a slow upload can lead to watchdog kills
if the app is suspended mid-upload. Instead, if the client can obtain
the lock, the database sets a lock-time file attribute and releases the
flock. The file attribute is cleared when the upload is completed. The
lock-time attribute can be used to prevent file access from other
processes, or to discard reports that likely were terminated mid-upload.

Because the upload thread uses synchronous upload, calling Stop() on
that thread from the main thread will lock, and trigger a terminate
when transitioning from foreground to background.
Additionally, background assertions now only last 30 seconds, so
shorten the timeout to 20 seconds.

This implements a per-report retry rate limit (as opposed to per upload
rate limit in ShouldRateLimitUpload). When a report upload ends in a
retry state, an in-memory only timestamp is stored with the next
possible retry time. This timestamp is a backoff from the main thread
work interval, doubling on each attemt. Because this is only stored in
memory, on restart reports in the retry state will always be tried
once, and then fall back into the next backoff. This continues until
5 retry attempts are reached.

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.

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.

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.

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.
