ae67cabe11 CMake: Make libc.a self-contained 
Previously, libc.a contained undefined symbols from ssp and libsystem,
which caused static compilation to fail.

We now generate libc.a with a custom CMake rule that combines all
object files from libc, ssp and libsystem to form libc.a

Closes #5758.

9588f01739 UserspaceEmulator+LibC: Use sys$emuctl() to pass malloc info to UE 
Get rid of the awkward secret handshake sequence between malloc and UE
and simply use sys$emuctl() to notify UE of malloc, free and realloc.

4faeaf101c LibC: Don't scrub memory in malloc/free when running in UE 
Since UE is keeping track of the heap anyway, we can skip the scrubbing
and drastically improve the speed of malloc and free when emulating.

2479ead718 Everywhere: Remove unnecessary clang-format offs 
Mostly due to the fact that clang-format allows aligned comments via
AlignTrailingComments.

We could also use raw string literals in inline asm, which clang-format
deals with properly (and would be nicer in a lot of places).

bb9cf083c4 LibC: Avoid double memory clearing in calloc() 
calloc() was internally calling malloc_impl() which would scrub out
all the allocated memory with the scrub byte (0xdc). We would then
immediately zero-fill the memory.

This was obviously a waste of time, and our hash tables were doing
it all the time. :^)

7db8ccc0e4 LibC+DynamicLoader: Move "transactional memory" GCC stubs to LibC 
Instead of having a special case in the dynamic loader where we ignore
TM-related GCC symbols, just stub them out in LibC like we already do
for various other things we don't support.

5d180d1f99 Everywhere: Rename ASSERT => VERIFY 
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)

Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.

We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.

43948aee51 LibC: Don't #define away __{BEGIN,END}_DECLS in stdarg.h 
That would force anything that includes this to have language-specific
linkage, and absolutely break `sys/cdefs.h`.

5729e76c7d Meta: Make it possible to (somewhat) build the system inside Serenity 
This removes some hard references to the toolchain, some unnecessary
uses of an external install command, and disables a -Werror flag (for
the time being) - only if run inside serenity.

With this, we can build and link the kernel :^)

bb777459a0 LibC+LibPthread: Implement pthread_atfork() 
This required a bit of rearchitecture, as pthread_atfork() required a
mutex, and duplicating a mutex impl for it was silly.
As such, this patch moves some standalone bits of pthread into LibC and
uses those to implement atfork().
It should be noted that for programs that don't use atfork(), this
mechanism only costs two atomic loads (as opposed to the normal mutex
lock+unlock) :^)
