Breakpad implementation for ios.

Breakpad implementation for ios.

 To be noted:
 1) All is done in process, as multi-process is not allowed on ios.
 2) Dump are saved when a crash occures but are not automatically send to the
    server.
 3) Breakpad.h contains function to check if a dump must be uploaded, and to
    upload a dump.
 4) The code is copy pasting a log of Breakpad implementation for Mac OS. It
    might be possible to do some refactoring.

LGTM mostly as a rubber-stamp.

I would prefer sharing code but the refactoring to get the #ifdefs to not be
terrible might be a bigger project than you want to take on.

I’m not actually going to reread the entire implementation of this file.
