libiberty, include: add bsearch_r
libctf wants a bsearch that takes a void * arg pointer to avoid a
nonportable use of __thread.
bsearch_r is required, not optional, at this point because as far as I
can see this obvious-sounding function is not implemented by anyone's
libc. We can easily move it to AC_LIBOBJ later if it proves necessary
to do so.
include/
* libiberty.h (bsearch_r): New.
libiberty/
* bsearch_r.c: New file.
* Makefile.in (CFILES): Add bsearch_r.c.
(REQUIRED_OFILES): Add bsearch_r.o.
* functions.texi: Regenerate.
