This is no right fix, we shouldn't allow module overlap.

In Android, the mmap could be overlapped by /dev/ashmem, we adjusted
the range in https://breakpad.appspot.com/9744002/, but adjusted
range isn't written back to module, this caused the corresponding
module be dropped in BasicCodeModules copy constructor.
This also fix a lot of 'unable to store module' warnings
when dumping Android's minidump.

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

If a crash occurred as a result to a write to unwritable memory, it is reason
to suggest exploitability. The processor checks for a bad write by
disassembling the command that caused the crash by piping the raw bytes near
the instruction pointer through objdump. This allows the processor to see if
the instruction that caused the crash is a write to memory and where the
target of the address is located.

If a MinidumpLinuxMapsList was created and destroyed without its Read method,
the program would have a segmentation fault because the destructor did not
check for a null maps_ field. Additional changes include additional
supplementary null checks, a potential memory leak fix, and some comment
removal.

when checking exploitability rating.
Linux minidumps do not support MD_MEMORY_INFO_LIST_STREAM, meaning the
processor cannot retrieve its memory mappings. However, it has its own
stream, MD_LINUX_MAPS, which contains memory mappings specific to Linux
(it contains the contents of /proc/self/maps). This CL allows the minidump
to gather information from the memory mappings for Linux minidumps.
In addition, exploitability rating for Linux dumps now use memory mappings
instead of checking the ELF headers of binaries. The basis for the change
is that checking the ELF headers requires the minidumps to store the memory
from the ELF headers, while the memory mapping data is already present,
meaning the size of a minidump will be unchanged.
As a result, of removing ELF header analysis, two unit tests have been removed.
Arguably, the cases that those unit tests check do not merit a high
exploitability rating and do not warrant a solid conclusion that was given
earlier.

There was already a method that found the instruction pointer, so the files

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.

and updating minidump_stackwalk to show process uptime.
I tested this with a minidump from Chrome and I got a result that
is inline with what the Windows debugger is showing for that dump:
minidump_stackwalk output:
--------------------------
Process uptime: 601 seconds
WinDBG output:
--------------
Process Uptime: 0 days 0:10:01.000
I didn't update the machine readable output of minidump_stackwalk
on purpose in order to avoid breaking someone that uses it.
It can be added later to the machine output if needed.

MINIDUMP_MISC_INFO_N structure. Added the necessary code for swapping and string conversion from UTF-16. Found and fixed a bug in MinidumpAssertion::Read where the max string length passed to UTF16codeunits was in bytes instead of UTF-16 chars.
Tested with a minidump containing a version 3 structure to validate the string conversion routines. Interestingly enough the time_zone names does not appear to be abbreviation as the documentation was suggesting but full names, e.g. Eastern Standard Time:
MDRawMiscInfo
size_of_info = 232
flags1 = 0xf7
process_id = 0x54c4
process_create_time = 0x51a9323c
process_user_time = 0x1
process_kernel_time = 0x0
processor_max_mhz = 3100
processor_current_mhz = 1891
processor_mhz_limit = 3100
processor_max_idle_state = 0x1
processor_current_idle_state = 0x1
The new fileds follow:
process_integrity_level = 0x1000
process_execute_flags = 0x4d
protected_process = 0
time_zone_id = 2
time_zone.bias = 300
time_zone.standard_name = Eastern Standard Time
time_zone.daylight_name = Eastern Daylight Time

errors and use the good data if possible.
More specifically:
- Detect corrupt symbols during minidump processing and provide the list of modules with corrupt symbols in the ProcessState. This will allow listing the corrupt symbol files in the final crash report.
- Skip and recover from symbol data parse errors - don't give up until 100 parse errors are seen.
- In order to recover from '\0' (null terminator) in the middle of a symbol file, a couple of methods have to be updated to require both buffer pointer and length. Previously they required only a buffer pointer (char *) and the size of the buffer was evaluated using strlen which is not reliable when the data is corrupt. Most of the changes are due to these signature updates.
- Added and updated unittests.
Also, updated minidump_stackwalk to show a WARNING for corrupt symbols. Output looks like this:

doesn't see the correct thread stack memory. Instead, it loads garbage
(from offset 0 of the minidump file - well that's not garbage, but it is
not the stack memory region either) and attempts to walk it. A typical
symptom of this issue is when you get a single stack frame after
processing - the context frame - for which you don't need stack memory.
This issue is caused by an invalid RVA in the memory descriptor stored
inside the MINIDUMP_THREAD structure for the thread. Luckily, the
invalid RVA is 0, and the start_of_memory_region appears to be correct,
so this issue can be easily detected and the correct memory region can be
loaded using an RVA specified in the MinidumpMemoryList.
I couldn't find a reasonable description on MSDN regarding
MINIDUMP_MEMORY_DESCRIPTOR.MINIDUMP_LOCATION_DESCRIPTOR having RVA of 0
except maybe for full dumps where the 64-bit version of the structure
(MINIDUMP_MEMORY_DESCRIPTOR64) is used and it has no RVA at all. It has
a 64-bit DataSize which if interpreted as the 32-bit structure will very
likely result in 0 for the RVA:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms680384(v=vs.85).aspx
Anyways, the dump that I looked at was not a full dump so 0 for RVA is a
bit puzzling (at least easily detectable):

(or not in a known module).
This is achieved by:
1. Extending the span of the scan for return address in the conext frame. Initially, I wanted to extend the span of the scan for all frames but then I noticed that there is code for ARM already that is extending the search only for the context frame. This kind of makes sense so I decided to reuse the same idea everywhere.
2. Attempting to restore the EBP chain after a successful scan for return address so that the stackwalker can switch back to FRAME_TRUST_CFI for the rest of the frames when possible.
I also fixed the lint errors in the files touched.
