libc: Add faster scandir function(scandir_sane).

This function is significantly faster due to not requiring memory
allocations for each directory entry. Now they are instead just
allocated as a large chunk. This function is not compatible with scandir
since the cleanup of both function will be different.

With this a new function scandir_sane_free has also been added.

Besides having a function(like scandir) that forces the programmer to
implement their own cleanup procedure that is anymore complicated than a
simple free() call is absurd.
