archive_xread can be replaced with bb_full_read, and archive_copy_file
with bb_copyfd*
bb_copyfd is split into two functions bb_copyfd_size and bb_copyfd_eof,
they share a common backend.
The tar -x command in busybox does not restore the file mode correctly.
The reason is most probably this code in
archival/libunarachive/data_extract_all.c:
chmod(file_header->name, file_header->mode);
chown(file_header->name, file_header->uid, file_header->gid);
chown clears the set*id bits (on current versions of linux :). Flipping
the order around fixes the problem.

In most cases, dirname returns the same argument it was given, so this code
works nice, but there's one special case: when the name contains no
dirname, it returns "." (stored statically in the body of itself), and we
get a segfault in attempt to free() it.
This patch fixes this problem.
