rtld_malloc: add __crt_aligned_alloc_offset()2023-08-21T14:16:42ZKonstantin Belousovkib@FreeBSD.org2023-07-22T04:21:45Zurn:sha1:c29ee08204ce4106d4992474005c5f2fb7d5fbf1
It is modelled after aligned_alloc(3). Most importantly, to free the
allocation, __crt_free() can be used. Additionally, caller may specify
offset into the aligned allocation, so that we return offset-ed from
alignment pointer.

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.

but still for tightly coupled things like ldd(1)
Rename paths.h to rtld_paths.h.
Add guard for rtld-specific externs declarations.
Add _COMPAT32_BASENAME_RTLD and _COMPAT32_PATH_RTLD.
