Bug 90265

Update to 3.6.2 for:
  BUGFIX: segfaults in daemon mode with hash_drv plus other hash_dvr fixes
  BUGFIX: for how token values are calculated, cutting false positives nearly
  in half
plus fixes for LDAP (close LDAP connection after calls, create database even
if LDAP fails):
  files/patch-CHANGELOG
  files/patch-src_ldap_client.c
  files/patch-src_mysql_drv.c
  files/patch-src_pgsql_drv.c

Drop local patch files/patch-src_libdspam.c incorporated upstream.

The memory leak is still here :(. At least now I think I know where and have a
potential fix that need more testing.

Since we could be running clamd on an other server make CLAMAV* options to only
enable clam support in dspam and provide an other option CLAMAV_LOCAL to
RUN_DEPEND on it locally; for POLA make this option default to on. RUN_DEPENDS
on package instead of clamd.conf in CLAMAV_LOCAL case.

Add MYSQL_LOCAL and POSTGRESQL_LOCAL options to RUN_DEPEND on servers.

REQUIRE mysql, postgresql or clam in rc script only if WITH_LOCAL_* is defined.

Also various clean-up in Makefile. Hmm, let's hope I didn't break anything in the
process.
