Merge handling of rancid-fe from upstream branch

This ensures rancid-fe actually gets built from rancid-fe.in and is
installed alongside all the other scripts.
Remove ">" from default prompt regex

For some reason, this really bothers zrancid, this seems like a working
quick fix. For more info about the issue, see:

Add script for Brocade SAN switches running FabOS

This script was originally posted to rancid-discuss by Rhys Evans at
http://www.shrubbery.net/pipermail/rancid-discuss/2011-January/005441.html

It's modified to use clogin rather than a separate brocadelogin, as
clogin appears to work just fine, and it's also been converted to .in
format (using configure macros like @PERLV_PATH@ where appropriate).
Revert "Remove ">" from default prompt regex"

This reverts commit 7a9df058f0013e76fce6e0e31474acaa58b47985.

Unfortunately, this quick-fix breaks brocaderancid. Need to find a
more proper solution
Workaround for old FabOS lacking config end marker

Old versions of Fabric OS (at least v5.3.0) is lacking the nice comment
that shows we've reached the end of the config that newer versions have.
LicenceDB is shown near the end, so just if we see that consider we've
found the end of the configuration.
Avoid pagination in showConfig for old FabOS

Old FabOS (v5.3.0) does pagination in a way that clogin doesn't handle
when doing showConfig. Pipe the output through "grep ." to avoid that.
Very Ugly Hack (so it fits nicely in with the rest of RANCID).
