[Crash Reporting] Implement a more direct bridge for extracting logcat output.

When a child process crashes, Chrome attempts to attach recent logcat
output to the minidump for the crash. Previously, this was implemented
via a FileObserver on the crash reports directory: When the file observer
detected a file moved into the directory, and saw that the filename
matched the appropriate regex pattern, it would attempt to append logcat
output. This has two drawbacks:
  (1) It's spooky action at a distance, which makes the code harder to
      reason about.
  (2) There's a super subtle constraint encoded into the "moved to" check:
      When the browser process crashes, a crash dump matching the same
      file pattern appears in the observed directory, but it is *created*
      rather than *moved*. Thus, this check is intentionally excluding
      browser crashes, for which the code might otherwise have a race
      between trying to attach logcat output and tearing down the main
      Java process.

This CL replaces the FileObserver with a direct call from the C++ code
that processes the minidump into the Java code that extracts the logcat.
(Well, there's some indirection to get through the Chrome layering onion,
but the flow is still much more linear.)

[Crash Reporting] Fix a race between uploading and appending logcat data.

Prior to this CL, files ending with ".dmp" could potentially be simulatenously
scheduled for appending logcat data and scheduled for upload. This CL resolves
the race by requiring a ".try0" suffix to be present prior to attempting an
upload.

http://crrev.com/2878193002 created a new Java dependency (//components/crash/android:java) for //components/crash/content/browser but only added the dependency to //chrome/android:chrome_java. There are other Android targets that depend on //components/crash/content/browser, for example, //chromecast/browser.

It is difficult to determine exactly which targets it needs to be added to since the android_library and source_set (or whatever C++ target) are not directly related.
