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.
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, ...).
Implementation no longer uses strtok_r(), it may be broken
or have an odd prototype.
Update configure not to check for strtok/strtok_r nor require
strtok_r to LDAP_API_FEATURE_X_OPENLDAP_REENTRANT.
