Kurt Zeilenga 1bcec8bf6a Add LBER_ and LDAP_ memory allocators/deallocators for internal
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, ...).
