Use strerror() if available.

to validate input dn's BEFORE sending dn's to server.
Also fixed getfilter to use REG_EXTENDED|REG_NOSUB.  (and fixed one
case where REG_BASIC was still used).
s/strdup/LDAP_STRDUP/
Added ldap_pvt_str2lower/upper

reflect its purpose.  Modify switch to support REG_EXTENDED expressions.
Use REG_EXTENDED instead of REG_BASIC everywhere.
Modify <ac/regex.h> to support <gnuregex.h> for testing purposes.
Requires: env CPPFLAGS="-DHAVE_GNUREGEX_H=1" LIBS=-lgnuregex ./configure

to build OpenLDAP.

Tests behave as expected excepting slapd sometimes does not
shutdown properly.

(test001-populate runs without leak)
Free global entry string buffer on shutdown.

New id2entry (id-less) format (ldbm/bdb2)

Needs a bit more work.
	- global net/api timeouts are not inherited on session creation.
	- need configure check for inet_aton() (coming soon)
	- ioctl/fcntl portability issues (should share implementation
		with lber routines)

s/exit(0)/exit(EXIT_SUCCESS)/
add <ac/stdlib.h> where needed and other minor header adjustments

This code is not called (yet).

Improve detection of FreeBSD FetchURL library.

If someone really lacks stdlib.h, they should introduce HAVE_STDLIB_H.

Probably should be moved to -llutil.
