More memory handling changes.  Need to sort out how to deal with strdup().

Add ber_memvfree(void** vector)

remove bogus libldap_r/apitest.ds[pw] files.

Add asserts and additional param checks.

(barely) hide more internals.

Only testavl uses this interface.

Use LDAP_MALLOC instead of ch_malloc

Modify apitest to test for non-zero instead of LDAP_OPT_ON.

instead of ABSTRACT.

Accept X- experimental clauses.

includes single to multiple hooks changes.
ber_mem* reimplementation.
namespace glue (finally naming has not be decided upon nor implemented).
Added ldap_int_strdup to handle "internal" strdup'ing, this version uses hooks.
ldap_pvt_strdup still available for when strdup() is missing, this version
directly uses system allocators.
Updated -lldif to use ber allocators.  Items returned by ldif routines
should be ber_memfree()d as needed.

Some definition reordering to satisfy dependencies.

Oops, fp_parse_line tokenizes in place, so we need to take a copy of
input before letting fp_parse_line ruin it.

Lose previously commented out old code.
Robustness fixes.
Fixed error reporting of non-existing attribute superior.

Relax some rules to survive Netscape DS brokennes, more to come.
A few parse_whsp were missing.
Detect and survive null input.

New error code for null string input.
