Minor bug fixes. Includes a fix for vchkpw to work with Sparc64 (and all
other new 64-bit architectures) and a fix for problems setting quota on
newly added users on MySQL systems using replication.
Stephan Tesch - md5.h: fix related to segfaults in vchkpw on Sparc64. 
Peter Seiderer - vcdb.c: vauth_getpw() didn't check for invalid domain.
Bill Shupp - vuserinfo: display spamassassin info.
Anonymous - vpopmail.c: Add missing ifdef that preventing modification of one-character username accounts.
Niki Denev - maildirquota.c: Remove double free() and fix use of free'd memory in docheckquota().  - contrib/qmail-maildir++.patch: same fix as for maildirquota.c.
Tom Collins - vlimits.c: print errors to stderr. - vmoduser.c: add clarity to usage/help for bit flags. - vcdb.c: be sure to close password file in vauth_getpw(). - md5.h: use cdb/uint32.h (built by configure) for defining uint32.  - vpopmail.c: fix vauth_user() to not clobber pw_uid and pw_gid. - vpopmail.c: If setting user quota for new user fails because newly created user does not exist, sleep 5 seconds and try again. (This can happen on servers using MySQL replication.) - Remove convert/vcalias.c and related files; vcalias was replaced by dotqmail2valias.
Michael Bowe - configure.in: fix typo of where the configure script says it is checking for qmail-inject when in fact it was checking for qmail-newmrh - Documentation updates to README.roamingusers. Mention the requirement of tcpserver for POP-before-SMTP. Also include some documentation on IMAP-before-SMTP.
