LibC: Rewrite malloc
...
The old linked list allocator with power of two pool sizes was kinda
weird. Now we use 1MiB bitmap allocators for allocations <64KiB and
directly call mmap for larger allocations. This allows userspace to
actually free unused memory on `free` :)

LibC: Make aio.h incudable in C++
...
aio stuff is not supported but now the header is at least includable in
C++ which was not possible before as __restrict was not allowed in array
size

LibC: Don't use ScopeGuard in exec
...
These ended up pulling `operator delete` which is not available when
linking with gcc :^)

LibC: Reorder stack trace dump printing
...
If we fault while getting start of stack frame at least we now print
that we were trying to get the stack trace :^)

LibC: Update argv[0] for shebang scripts to full path
...
This is needed so `dirname -- "$0"` works with shebang scripts found in
PATH

Kernel: Pass current cpu index as a GDT limit
...
I had no idea LSL was an instruction. This cleans up code to get the
current cpu by a lot and does not require extra segment usage :D

Userspace: Install libdl, libm, libpthread as symlinks to libc

LibC: Define pthread_{equal,self} as macros

LibC: Don't complain about stack size until 8192 bytes
...
It was unnecessary as userspace stack is way bigger than that...

LibC: Use __builtin_thread_pointer for _get_uthread()
...
This generates much nicer assembly as it does not have to read thread
pointer for every access to TCB (errno, cancel_state, cancelled) and
instead it can read it once and use the same value for all accesses

LibC: Use IP instead of si_addr for faulting instruction
...
si_addr only means faulting instruction for SIGILL. For SIGSEGV it is
the faulting memory address.

Kernel/LibC: Rework userspace syscall interface
...
Kernel syscall API no longer zeros all unused argument registers and
libc now uses inlined syscall macro internally. This significantly
cleans up generated code for basic syscall wrapper functions.

LibC: Fix pthread cancellation
...
Install SIGCANCEL handler for all threads.
Remove unneeded atomic stores and loads. States are only changed within
the thread itself.
Define pthread_testcancel as a macro so it gets inlined inside
cancellation points

LibC: Implement blocking pthread_rwlock

pthread_rwlock now uses a mutex and condition variable internally so it
