Fix LDAP_MEMORY_DEBUG realloc size bug, thanks Alex.

Fixed inconsistent management of white space that was producing parsing
problems in slapd.

Minor cosmetic changes.
Fixed parsing of noidlen.

Make sure LBER_INTIALIZED is set on any ber_mem* call.

Add detection for duplicate free in LDAP_MEMORY_DEBUG code.

Added place holder for LDAP_FILTER_EXTENDED code.
Added assert() here and there and removed lint.
Removed version promotion code (version must be manually set).
Added messages.c to MSVC project.

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.
