LibC: Cleanup qsort implementation
...
Remove random template and just make qsort be a wrapper around qsort_r
Recurse only into the smaller partition. This removes the possibility of
O(n) recursion in the worst case
Use insertion sort for ranges shorter than 16 elements.
Split qsort_swap into qsort_swap_fixed and qsort_swap_general
- fixed one handles 1, 2, 4 and 8 byte elements which can be done directly
with mov instructions
- general copies 64 bytes at a time followed by a single copy for the
rest. the 64 byte chunk loop gets nicely optimized into sse

This is not really required by anything but i've seen few ports
optionally use it if available. This was trivial to implement so why not
add it :^)

Also remove hardcoded type -> size mappings and just use a looup table

Kernel/LibC: support RDTSCP based clock_gettime

LibC: Wait for thread before returning from pthread_create
...
We now make sure the thread starts up and sets its id. There was a race
condition where a process could create a thread and immediately try to
join it. If the thread had not initialized itself the join would fail
with EINVAL as we passed -1 as its id.

Kernel: Remove SYS_SLEEP and cleanup SYS_NANOSLEEP
...
`sleep` is now implemented in terms of `nanosleep`. `nanosleep` is now
more precise and handles overflow when calculating wakeup time. I don't
think anything was depending on this, but I could see a program sleeping
for max time to block until signal.
