Ivan Penkov 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.

Veljko Mihailovic 6ce752d741 Support processing microdump for mips architecture
Based on changes for ARM, ARM64 and X86, the support for
MIPS and MIPS64 is added in microdump.

Maria Mandlis f3d28e9c4a Handle multiple microdumps in system log.
Properly handle microdump processing, when the system_log file contains an incomplete microdump section at the top. The processor will process the first complete microdump section.

Maria Mandlis df280bb631 Parse additional line introduced in the microdump format and containing the GPU infromation in the following format:
G GL_VERSION|GL_VENDOR|GL_RENDERER.

The GPU version, vendor and renderer are extracted during microdump parsing and populated in the appropriate fields in the SystemInfo struct.

This is to match the changes introduced in crrev.com/1343713002 and crrev.com/1334473003

mmandlis@chromium.org 3f4d090d70 The "CPU architecture" field is being filled from the wrong part of
the microdump. The microdump OS/arch line looks like:
O A arm 04 armv7l 3.4.0-perf-g4d6e88e #1 SMP PREEMPT Mon Mar 30 19:09:30 2015
and currently the field that says "armv7l" or "aarch64" is being used
to fill in the CPU arch field in crash. The problem is that on a
64-bit device this field *always* says "aarch64" even when running in
a 32-bit process, and so currently the crash reports for aarch64 are
a mix of 32-bit and 64-bit crashes. We should be using the first field
instead, which just says "arm" or "arm64" and reflects the actual
version of webview (32-bit or 64-bit) which is running.

primiano@chromium.org 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.

mmandlis@chromium.org 1c822b7768 Introduce stub microdump processor classes.
Adds the interfaces for MicrodumpProcessor (very similar to
MinidumpProcessor) and corresponding unittest stubs.
These stubs are required for multi-side integration and to start
rolling the updated processor library into the dependent projects.
