commit a308db6587c866826a280a60b841f0a3926c1078

s3-netlogon: enumerate UPN suffixes from PASSDB when available
Optionally append list of UPN suffixes if PDB module returns non-empty one.
Refactor fill_forest_trust_array() in source3 to allow reuse of the code between
_netr_DsRGetForestTrustInformation() and _netr_GetForestTrustInformation()
Implement a special case of _netr_DsRGetForestTrustInformation in smbd
when trusted_domain_name is NULL (covered by test_DsrEnumerateDomainTrusts()
in rpc.netlogon torture tests, see comment in source4/torture/rpc/netlogon.c).

commit 5952755755fb0ea7f942bb564ca1cfdca5730113

PASSDB: add support to set and enumerate UPN suffixes associated with our forest
Samba PDC may manage a forest containing DNS domains in addition to the primary one.
Information about them is advertised via netr_DsRGetForestTrustInformation when
trusted_domain_name is NULL, according to MS-NRPC and MS-LSAD, and
via netr_GetForestTrustInformation.
This changeset only expands PASSDB API; how suffixes are maintained is left
to specific PDB modules. Set function is added so that suffixes could be
managed through 'net' and other Samba utilities, if possible.
One possible implementation is available for ipasam module in FreeIPA:

s3-waf: filter out ldapsam internal init functions
pdb_ldapsam_init* functions (init and init_common) are used in
pdb_ipa.c and pdb_nds.c which are always linked together with
pdb_ldap.c where pdb_ldapsam_init* functions reside.
Tested with both ldapsam integrated (into libpdb) and as
a separate module.

wafsamba: fix samba_abi for default catch-all case
Only filter out the symbol when positive match was not found and there is
negative match.
ABI signature file generator worked incorrectly for cases when mixture of
positive and negative matches were provided. This resulted in generating empty
signature file for libpdb since there was no catch-all positive match anymore.
Commit 9ba44cc610426fb558b49aa9680b5bdf55c29082 removed explicit '*' positive
match and corresponding vscript generator adds '*' by default if global match
list is empty, so this commit introduces feature parity into signature
generator.
