Server-side workaround to handle overlapping modules.

This change is resolving an issue that was caused by the combination of:
 - Android system libraries being relro packed in N+.
 - Breakpad dealing with relro packed libraries in a hack way.

This is a fix for http://crbug/611824.

I also found an use-after-free issue (bug in Minidump::SeekToStreamType).  I disallowed the MinidumpStreamInfo copy and assign constructors and the compiler detected another similar issue in Minidump::Print.  Then I disabled the copy and assign constructors for most classes in minidump.h (just in case).  There are a couple of classes where I couldn't disallow them (since assign is used).  This will require a small refactor so I left it out of this CL.
