243dffb045 ios: Stop prune and upload thread when app is inactive and may suspend.
Stop the prune thread and the upload thread when moving to the
inactive/background state. This will reduce the number of 0xdead10cc
system kills from having a file lock during iOS suspend.

Wait to start the prune thread when the application is active.
Otherwise, for iOS prewarmed applications, the prune thread will
regularly start when the application is foregrounded for the first
time when the user intentionally runs the app.

It's still possible for either the prune thread or the upload thread to
have a file lock during iOS suspend, such as when a task started in the
foreground and does not complete in time for suspension. Future work
should include considering BackgroundTasks and/or NSURLSessions, which
can more safely run in the background.

2d5a30fb17 ios: Create a PruneIntermediateDumpsAndCrashReportsThread.
This will prune the database on a daily basis, in accordance with the
specified condition. This will also unlock any leftover intermediate
dump files.

c367128a85 ios: Don't use POSIX file locks for iOS intermediate dumps.
Instead use a custom mechanism based on the filename. Rather than a
filename of <uuid>, instead name the file <bundle-id>|<uuid>[.locked].
A locked file will have the optional .locked extension. Files can be
unlocked after writing an intermediate dump, or during initialization by
looking for matching bundle-ids.

Clients that call ProcessIntermediateDumps() will clean up any leftover
locked intermediate dumps. Clients that never call
ProcessIntermediateDumps, such as extensions that leave this up to the
main application, will be cleaned up in a followup change.

af62d7fcf6 Correct use of -[NSString UTF8String].
Fixes the chromium presubmit error for UTF8String:
 The use of -[NSString UTF8String] is dangerous as it can return null
 even if |canBeConvertedToEncoding:NSUTF8StringEncoding| returns YES.
 Please use |SysNSStringToUTF8| instead.

d9c1ca1216 [ios] Bring up first draft system snapshot and iOS data collector.
Gather most of the necessary information for the system snapshot.

Note that:
 - The 'capture' portion of this CL will be moved out of the snapshot
   interface and into a separate in-process dump to disk location.
 - All of the pointer dereferences need to be wrapped in vm_read.
 - The read-fast-and-dump logic in thread_snapshot may end up in a
   different file completely, but until we pick a
   serialization/deserialization method, keep it as-is.
