1922d78661 Kernel: Add support for mkfifo{,at} mkdir at 
Opening FIFOs still dont work as expected but at least you can create
them now :D

68479bf07e userspace: Fix getopt_long usage 
- Add missing null entry after the last long option
- Don't duplicate illegal option message, getopt already prints
  the message as I do not suppress it. Also handle missing arguments.

fe2c9f7d2d 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` :)

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

212ab010a5 BAN: Expose radix sort with user provided buffer 
This can be nice if user has memory for a the temporary buffer and
doesnt want the sorting to allocate or be able to fail.

Also counts are now stack allocated, there isn't really any reason to
allocate them on the heap as 256x 64 bit values only adds up to 2 KiB

fde085e04b 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

40f3546aca BAN: Rewrite HashMap as a wrapper around HashSet 
There is really no need to have two implementation of the same thing.
Only difference now is that HashMap's value type has to be movable but

aaade52146 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

3ebadc5c74 LibDEFLATE: Optimize decompression 
Instead of calculating bit-by-bit crc32, we now calculate a lookup table
during compile time. The old crc32 calculation was taking almost 50% of
the decompression time.

Also handle multiple symbols at once without outputting to user. It is
much more efficient to output many bytes instead of the up to 258 that a
single symbol can decode to :^)

instead the decompressor reports to the user if it needs more input or
