Toy with dllimport/dllexport stuff (think I'll leave the real dll work to
somebody else).
Added ldap_strdup() wrapper of ber_strdup().

and ripple change through -lldap.

Make _MOD_SOFTADD 0x1000 to minimize chance of conflict with legit changes
to API spec.
Fix memory leak in ldap_mods_free() and minor memory allocator issues.

Add ber_memvfree(void** vector)

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

Add asserts and additional param checks.

Only testavl uses this interface.

Use LDAP_MALLOC instead of ch_malloc

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

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.

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

myrealloc is pointer to a realloc() wrapper.
Must be first library call or else.

Fixed parsing of noidlen

library use:
  LBER_ macros expand to system routines.
  LDAP_ macros expand to new ber_ allocators.

Add ber_ and ldap_ memory allocators/deallocator:
  ber_ routines are wrappers of LBER_ macros.
  ldap_ routines are wrappers of ber_ routines.

Removed safe_realloc() macro from various files.  This issue
(if an issue) should be resolved across whole package.

ldapmodify.c now uses ber_ allocators to resolve ber_bvfree()
vs. WIN32 multiple heaps issue.

These changes should facilate implementation of
  ber_set_option( NULL, LBER_OPT_MEMORY_FN, ...)
and
  ldap_set_option( NULL, LDAP_OPT_MEMORY_FN, ...).

Added validation to exposed opaque data structures (BerElement, Sockbuf,
and LDAP).  Added macros BER_VALID, SOCKBUF_VALID, LDAP_VALID.
Added ber_pvt_ber_bytes() and ber_pvt_ber_remaining() macros to hide
some ber internals.  These really should be handled by ber_get_option().
