RANCID scripts for Nortel BayStack devices

These files add support for Bay Networks/Nortel/Avaya BayStack/BPS/ERS switches to RANCID. I based these changes on ones we've been running in production for over a decade and I've tested this extensively on models BPS 2000, 470, and ERS 25xx/45xx/55xx/56xx.

Initially I copied clogin to bslogin, but I've included a patch for the original rancid-3.9 clogin because I believe it should be safe to apply to the original and eliminate the need for a separate login script. I rearranged a few conditionals related to Extreme support to make the logic easier for the BayStack and other future differences.

It was a PITA to get past the BayStack login banner, but I finally found a workable solution that should hopefully not interfere with other device types and should support BayStacks that have the stock banner, a custom banner, or the banner turned off. The only potential concern for impact to non-BayStack devices is the matching on ##+ used to skip past the banner to avoid it being interpreted as a # prompt character. I'm now running this in production as my clogin and so far there have been no impacts to Aruba devices, the only other devices I have that use clogin.

Instructions:

1. Copy baystack.pm to the same place where you have your RANCID perl modules or to one of the directories listed in your rancid.conf PERL5LIB environment variable, e.g.:

PERL5LIB="/usr/share/perl5/vendor_perl/rancid:/usr/local/share/perl5/rancid"; export PERL5LIB

2. Copy bslogin to the same place where you have your RANCID clogin file or to one of the directories listed in your rancid.conf PATH environment variable, e.g.:

PATH=/usr/libexec/rancid:/usr/local/libexec/rancid:/usr/bin:/usr/sbin:/usr/local/bin; export PATH

3. Make the bslogin script executable:

chmod 755 bslogin

4. Append the contents of rancid.types.conf.baystack to your existing rancid.types.conf.

5. Configure router.db entries with type baystack, e.g.:

bps-switch;baystack;up
470-switch;baystack;up
ers-5520-switch;baystack;up
