This change is essentially a mechanical change which moves the thread
creation and join implementations from src/threads/linux to
src/__support/threads/linux/thread.h. The idea being that, in future, a
pthread implementation can reuse the common thread implementations in
src/__support/threads.

Instead, memory is allocated and deallocated using mmap and munmap
syscalls directly.

This patch applies the lint rules described in the previous patch. There
was also a significant amount of effort put into manually fixing things,
since all of the templated functions, or structs defined in /spec, were
not updated and had to be handled manually.

Also, added a call to munmap on error in thrd_create.

This allows others parts of the libc to use the mutex types without
actually pulling in public function implementations.
Along the way, few cleanups have been done, like using a uniform type to
refer the linux futex word.

this will make sure that all of the functions are using the correct
prototypes. Explained much better in the comments of this diff:

Summary:
The new macro also inserts the C alias for the C++ implementations
without needing an objcopy based post processing step. The CMake
rules have been updated to reflect this. More CMake cleanup can be
taken up in future rounds and appropriate TODOs have been added for them.

The following are the differences from the first version:
1. The kernel does not copy the stack for the new thread (it cannot).
The previous version missed this fact. In this new version, the new
thread's start args are copied on to the new stack in a known location
so that the new thread can sniff them out.
2. A start args sniffer for x86_64 has been added.
2. Default stack size has been increased to 64KB.
