This patch allows LLDB for AArch64 to watch all bytes, words or double words individually on non 8-byte alligned addresses.
This patch also adds tests to verify this functionality.

The structure definitions are not provided, but we perform a sizeof operation of
them which causes a build failure. Include `asm/ptrace.h` to get the structure
definitions.

This patch corrects the number of bytes of debug register resources which are written while installing or removing a breakpoint using ptrace interface on arm64 targets.

Summary:
This commit integrates MainLoop into NativeProcessLinux. By registering a SIGCHLD handler with
the llgs main loop, we can get rid of the special monitor thread in NPL, which saves as a lot of
thread ping-pong when responding to client requests (e.g. qThreadInfo processing time has been
reduced by about 40%). It also makes the code simpler, IMHO.

This is a resubmission of r242305 after it was reverted due to bad interactions with the stdio
thread.

Summary:
This changes PtraceWrapper to return an Error, while the actual result is in an pointer parameter
(instead of the other way around). Also made a couple of PtraceWrapper arguments default to zero.
This arrangement makes a lot of the code much simpler.
Test Plan: Tests pass on linux. It compiles on android arm64/mips64.

Summary:
This removes a lot of boilerplate, which was needed to execute monitor operations. Previously one
needed do declare a separate class for each operation which would manually capture all needed
arguments, which was very verbose. In addition to less code, I believe this also makes the code
more readable, since now the implementation of the operation can be physically closer to the code
that invokes it.
Test Plan: Code compiles on x86, arm and mips, tests pass on x86 linux.

This change reorganize the register read/write code inside lldb-server on Linux
with moving the architecture independent code into a new class called
NativeRegisterContextLinux and all of the architecture dependent code into the
appropriate NativeRegisterContextLinux_* class. As part of it the compilation of
the architecture specific register contexts are only compiled on the specific
architecture because they can't be used in other cases.
The purpose of this change is to remove a lot of duplicated code from the different
register contexts and to remove the architecture dependent codes from the global
NativeProcessLinux class.
