Log message:
Update roller to 1.20.

proc-maillog:
- Use "-d yesterday" to get more correct statistics on the typical case of
  rotating logs at midnight.
- Add smtpd connection statistics.
- Remove per-user top 10 lists.

proc-messages:
- Message updates:
  - New messages: Cyrus, HP printers, ISC dhcpd, NetBSD kernel, Net-SNMP
    and ProFTPD.
  - Account for views in more BIND named messages.
  - Handle rsnapshot, smartd and Sipura SIP phones/gateways.
- Logic fixes:
  - Facilities don't always have a trailing colon (esp. on non-UNIX).
  - Remove sequence number and extra timestamp from Cisco messages.
  - Keep $origin per-host, so "last message repeated" is logged correctly.
  - Log only remote host when counting warnings for different software,
    so the thresholds are tripped more easily (the account used is not
    considered as important, since dictionary attacks are common).
- Code maintenance:
  - Modernise Perl subroutine calls (no ampersand).
  - Centralise host[addr] string parsing.
  - Some whitespace cleanup.
- Configuration changes:
  - Update $LOCAL (should go into a config file).

roller:
- Use "uname -n" instead of "netname", so network \ 
connectivity is not used.

Log message:
Use MAKE_FLAGS.

Log message:
Replaced "# defined" with "yes" in Makefile variables like \ 
GNU_CONFIGURE,
NO_BUILD, USE_LIBTOOL.

Log message:
Get rid of USE_PERL5.  The new way to express needing the Perl executable
around at either build-time or at run-time is:

	USE_TOOLS+=	perl		# build-time
	USE_TOOLS+=	perl:run	# run-time

Also remove some places where perl5/buildlink3.mk was being included
by a package Makefile, but all that the package wanted was the Perl
executable.

Log message:
Add RMD160 digests.

Log message:
Bump PKGREVISION for dependency change.

Log message:
Add netname to DEPENDS (was missing).
