LibC: Support in-place realloc for mmap backed allocations
...
When shrinking a mmap based allocation, we can just unmap the trailing
pages that will no longer be needed. When extending an allocation we try
to MMAP_FIXED_NOREPLACE the need extra data to avoid memcpy between old
and new allocation. I'm not sure if the extension logic is really worth
it but it is just 15 lines of code to avoid possibly very large memcpys.

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
