Validate starttime and stoptime format

Be more precise to match members of a bridge interface, it should fix #3637

Do not allow interface group name to be bigger than 15 chars, helps ticket #3208

Add some protection to parameters that come through _GET

remove openbgpd bits from system_gateways_edit and system.inc. The package
match is case-sensitive and hasn't matched the openbgpd package's name in
at least 5 years, so it doesn't do anything. It's far from functional in
any useful manner even fixing that issue.

Unset iflist and iflist_disabled

Show disabled interface when it was already part of interface group, it avoids to show a random interface instead and let user to add it by mistake. It should fix #3680

add guiconfig to widgets not including it. ticket #3498

remove text not relevant to Allowed IPs. Ticket #3594
