Earlier we used to call 'adb logcat' and get all the logs and send
those. This didn't work on iOS and we wouldn't get all the logs even in
android at times as the logcat buffer can be unreliable.
Since now we log all the messages to a file, we can just send that file.
The disadvtange is that we only get Dart level logs, and not iOS or Java
or NDK or our C libraries logs.
I should really dump libgit2 ASAP.
This will show all the debug messages, which include when a file is
being ignored and not loaded, and hopefully all the exceptions. So the
user should be able to better understand why a file has been ignored.
It's not an ideal solution, but it's a quick fix.
Fixes#122
For Bug reports we were calling 'adb logcat' and fetching the logs, but
the amount of logs we got was quite arbitrary, also this wasn't possible
in iOS.
With this approach, we don't get the lower level logs of Android/iOS or
from libgit2, but since we're slowly moving away from libgit2 anyway, it
will have to do.
