04b2ab5bba port: fix non-glibc desktop linux build
This is the only change needed to build crashpad against musl, yay! The
reason this change is needed is that user_vfp is bionic-specific, and
does not exist in glibc, dietlibc, uclibc, or musl.

I have not (yet) tried running the tests against another libc.

cb41ba7471 Added MIPS support to crashpad.
Modified gyp/gn files to support MIPS targets.

Implemented thread_info, cpu_context, signal context classes for MIPS target.

Addressed MIPS specific signal ordering.

Added "MIPS Technologies, Inc." to AUTHORS file.

08ce02c352 Fix crashpad build on non Android ARMEL with a recent GLIBC.
user_vfp is not declared anymore in sys/user.h, but in specific
internal kernel asm user.h in GLIBC. So building crashpad on ARMEL
with such a GLIBC will fail to build.

Also, sys/ptrace.h will not include the declarations for
PTRACE_GET_THREAD_AREA and PTRACE_GETVFPREG in arm (they are in
asm/ptrace.h and not included from sys/ptrace.h). So provide
compatibility declarations accordingly for arm architecture.

59c5d848e5 linux: Refactor ptrace usage.
1) Add PtraceConnection which serves as the base class for specific
types of connections Crashpad uses to trace processes.
2) Add DirectPtraceConnection which is used when the handler process
has `ptrace` capabilities for the target process.
3) Move `ptrace` logic into Ptracer. This class isolates `ptrace` call
logic for use by various PtraceConnection implementations.

8fb23f2acc linux: Provide ThreadInfo to collect register sets with ptrace
ThreadInfo provides a uniform interface to collect register sets or
the thread-local storage address across bitness for x86 and ARM family
architectures. Additionally, ThreadInfo.h defines context structs which
mirror those provided in sys/user.h. This allows tracing across bitness
as the structs in sys/user.h are only provided for a single target
architecture.
