b2fd7d5307 [ios] Bring up first half of UncaughtExceptionHandler.
When code raises an Objective-C exception, unwind the stack looking for
any exception handlers. If an exception handler is encountered, test to
see if it is a function known to be a catch-and-rethrow 'sinkhole'
exception handler. Various routines in UIKit and elsewhere do this, and
they obscure the exception stack, since the original throw location is
no longer present on the stack (just the re-throw) when Crashpad
captures the crash report. In the case of sinkholes, trigger an
immediate exception to capture the original stack.

The is an improvement over the alternative,
NSSetUncaughtExceptionHandler, which passes along the stack frames, but
not the stack memory contents and full exception context itself.

The details of what happens after a fatal exception is triggered are
unresolved in this CL.  For now, simply call std::terminate.

This code was inspired by chromium/src/chrome/browser/mac/
exception_processor.mm.

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.
