88d8114fda Define and use a a new MDRawContextARM64
This struct matches the layout defined by Microsoft and replaces
Breakpad's MDRawContextARM64_Old. This CL updates the processor to
understand either the old or new structs, but clients continue to write
the old structs.

3d6076efc2 Add -s flag to microdump_stackwalk for dumping stack contents.
Note that the current MicrodumpProcessor::Process implementation has a
bug due to the fact that it creates a local Microdump instance, and then
holds onto a pointer to the object returned by microdump.GetMemory()
which is destroyed when microdump goes out of scope. This CL fixes the
crash by making Microdump outlive MicrodumpProcessor, which is the same
pattern that Minidump/MinidumpProcessor uses.

24f5931c5e 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.

0b6cc95246 Microdumps: support aarch64 and lib mapping from APK
- Filter modules by prot flags (only +x) not extensions. It wouldn't
  otherwise catch the case of Chrome mapping the library from the
  apk (which is mapped r-x but doesn't end in .so).
- Use compile-time detection of target arch, in order to cope with
  multilib OSes, where uname() doesn't reflect the run-time arch.
- Add OS information and CPU arch / count.
- Add support for aarch64.
- Add tests and stackwalk expectations for aarch64.
- Fix a potential overflow bug in the processor.
- Rebaseline the tests using smaller symbols.
- Fix microdump_writer_unittest.cc on 32-bit host.
