Microdumps are a very lightweight variant of minidumps. They are meant
to dump a minimal crash report on the system log (logcat on Android),
containing only the state of the crashing thread.
This is to deal with cases where the user has opted out from crash
uploading but we still want to generate meaningful information on the
device to pull a stacktrace for development purposes.
Conversely to conventional stack traces (e.g. the one generated by
Android's debuggerd or Chromium's base::stacktrace) microdumps do NOT
require unwind tables to be present in the target binary. This allows
to save precious binary size (~1.5 MB for Chrome on Arm, ~10 MB on
arm64).

This change introduces the necessary glue typedefs to deal with the
mismatch introduced by the latest Android NDK (w.r.t. desktop Linux):
- [x86_64] Rename fpregs mxcr_mask -> .mxcsr_mask
- [mips] uc_mcontext.fpregs.fp_r.fp_dregs -> uc_mcontext.fpreg
- [mips] restore the forked user.h

Prior to NDK r10c, Breakpad was privately backporting these system
headers. This change is now unforking and removing those headers and
using the ones from the NDK.
Rationale:
- They are finally available in the NDK, so there is no need to keep
maintaining a fork (which was necessary up until recently to support
arm64).
- These forked headers, as they are today, are not compatible with the
latest NDK (i.e. this change is required to roll NDK r10c).
The forked ucontext.h, being removed by this CL, depends on some
transitional features which are not compatible with the NDK release
being targeted here.
After this change, the NDK r10c is now required to build Breakpad on
Android. Note that NDK releases are backwards compatible and contain all
the previous API levels, so this change is NOT effectively enforcing to
build against any particular Android SDK.

This reverts r1394.
Reason for the revert: r1394 is breaking compatibility with previous
NDK (< r10c).

This is a refactoring of the logic which determines the
module name and path for a given MappingInfo in minidump_writer.cc.
Such logic, which will be soon shared also with the upcoming
microdump_writer.cc, is simply being moved to linux_dumper.cc,
extracting a GetMappingEffectiveNameAndPath method.
No behavioral change is intended.

Server is used is done by subtracting the crashing process creation time from
the current time when the crash is generated:
uptime = now - process_creation_time
There was a bug and instead of the process creation time the code was using the
time when the process was registered with the Crash Generation Server.

This change is a pure refactoring of the common bits of minidump_writer.cc
that will be shared soon with the upcoming microdump_writer.cc.
In particular, this CL is extracting the following classes:
- ThreadInfo: handles the state of the threads in the crashing process.
- RawContextCPU: typedef for arch-specific CPU context structure.
- UContextReader: Fills out a dump RawContextCPU structure from the
ucontext struct provided by the kernel (arch-dependent).
- SeccompUnwinder: cleans out the stack frames of the Seccomp sandbox
on the supported architectures.
- MappingInfo: handles information about mappings

When parsing /proc/pid/maps, current code merges adjacent entries that
refer to the same library and where the start of the second is equal to
the end of the first, for example:
40022000-40025000 r-xp 00000000 b3:11 827 /system/lib/liblog.so
40025000-40026000 r--p 00002000 b3:11 827 /system/lib/liblog.so
40026000-40027000 rw-p 00003000 b3:11 827 /system/lib/liblog.so
When the system linker loads a library it first reserves all the address
space required, from the smallest start to the largest end address, using
an anonymous mapping, and then maps loaded segments inside that reservation.
If the loaded segments do not fully occupy the reservation this leaves
gaps, and these gaps prevent merges that should occur from occurring:
40417000-4044a000 r-xp 00000000 b3:11 820 /system/lib/libjpeg.so
> 4044a000-4044b000 ---p 00000000 00:00 0
4044b000-4044c000 r--p 00033000 b3:11 820 /system/lib/libjpeg.so
4044c000-4044d000 rw-p 00034000 b3:11 820 /system/lib/libjpeg.so
Where the segments that follow this gap do not contain executable code
the failure to merge does not affect breakpad operation. However, where
they do then the merge needs to occur. Packing relocations in a large
library splits the executable segment into two, resulting in:
73b0c000-73b21000 r-xp 00000000 b3:19 786460 /data/.../libchrome.2160.0.so
> 73b21000-73d12000 ---p 00000000 00:00 0
73d12000-75a90000 r-xp 00014000 b3:19 786460 /data/.../libchrome.2160.0.so
75a90000-75c0d000 rw-p 01d91000 b3:19 786460 /data/.../libchrome.2160.0.so
Here the mapping at 73d12000-75a90000 must be merged into 73b0c000-73b21000
so that breakpad correctly calculates the base address for text.
This change enables the full merge by also merging anonymous maps which
result from unused reservation, identified as '---p' with offset 0, and
which follow on from an executable mapping, into that executable mapping.

This CL adds three features that will allow the client to upload the report
file.
Three main modifications are made :
- Allow upload url to have a file:// scheme, and write the HTTP request to file
in that case
- Split the request in two parts in case of a file:// scheme, the request
time and the response time. A new API [handleNetworkResponse] is added.
- Give the opportunity to the client to get the configuration NSDictionary
to be able to recreate the breakpad context at response time.

the dSYM.
This adds a new |-g <dSYM path>| flag to dump_syms, to specify the dSYM path for
the target Mach-O argument. The UUIDs and architectures of the two paths must
match in order to dump symbols for this "split module."
This reason for this is that for x86_64 binaries on OS X, the CFI data is stored
in the __TEXT,__eh_frame segment of the Mach-O file, and the data is not copied
into the dSYM by dsymutil. Therefore, just dumping the dSYM doesn't yield CFI
data for x86_64 files, and both the dSYM and the Mach-O file must be dumped in
order to produce a complete Breakpad symbol file. For i386 binaries, the CFI data
is stored in the __DWARF,__debug_frame segment, which is part of the dSYM, so
this isn't necessary.

This GYP-ifies the src/processor and src/common directories on those platforms

the new processor_unittests does not yet link because of multiple main() symbols,

APK file.
This patch makes two changes to breakpad to enable crash reporting to work correctly when the library is inside another file (an archive):
- Do not filter mappings which map an executable at a non-zero offset.
- If such an executable is mapped look in the ELF information for the
shared object name and use that name in the minidump.
Note this change doesn't care about the archive format and isn't Android
specific (though loading the shared library this way is currently only done on Android).

Google at this moment. This change is implementing a workaround that
allows switching to hash_set and hash_map.

WriteOSInformation.
__system_property_get has been removed from the Android NDK for 'L' so Breakpad
no longer links. This CL just removes the call in WriteOSInformation because
Chrome already passes the build fingerprint as a crash key called "android_build_fp" in the crash report HTTP POST message.

After handling an uncaught NSException, release the Breakpad object
so there will not be a second crash dump logged.
Prior to this change, for every uncaught NSException handled through
the Breakpad::UncaughtExceptionHandler(), a second crash without
any useful information (generally __cxa_rethrow and std::__terminate)
is recorded.

This bug manifests itself on Android x64 (in ExceptionHandlerTest::ExternalDumper), but is possible on any platform.
The compiler is unaware of the code which runs in the signal handler which reads this variable. Without volatile the compiler is free to optimise away writes to this variable which it believes are never read.
