Improve error diagnostics in UserCollector.
This CL makes the following changes to improve error diagnostics in
UserCollector:
1. Add an error type to describe why the crash reporter fails to
collects a user crash, which is reported to the crash server along
with the "crash_reporter-user-collection" error signature.
2. Perform some preliminary validations of the core file before
converting it to a minidump file using core2md.
3. Identify the case when a 32-bit core file is produced on a 64-bit
platform as core2md currently cannot handle 32-bit core files on
a 64-bit platform.
