Change Details

To be used later in libthr. Note that malloc_aligned() in the rtld/xmalloc.c has additional requirements (offset) and cannot be that easily replaced by __crt_aligned_alloc(). ``` rtld_malloc: remove outdated comments The ovu_magic is not neccessary overlaps with low byte of the ov_next, for the big endian machines. There is no range checking in the allocator. ``` ``` rtld: remove dup __crt_malloc prototypes ``` ``` rtld_malloc: only include internal rtld headers when building for rtld ``` ``` rtld_malloc: add cp2op() helper converting user allocation address into overhead pointer ``` ``` rtld_malloc: add __crt_aligned_alloc() It is modelled after aligned_alloc(3). Most importantly, to free the allocation, __crt_free() can be used. ```
