Update to postfix 19991231-pl10. Install LDAP_README and MYSQL_README along
with documentation. Fix manpage generation. Consistently use INSTALL_*
macros (from postfix-current). Modify packaging list using WITH_PCRE and
WITH_LDAP PLIST_SUBs (as per postfix-current). Add knob to enable PCRE (again
from postfix-current). Use better package description (postfix-current). Fix
PLIST. Conditionally remove main.cf and master.cf when they are unmodified
from default (postfix-current). Fully institute new maintainer as a real one.
