zino1 protocol: parameter case-sensitive inconsistencies with tcl implementation

[runborg]

In the original zino implementation there are a few parameters that use upper-case characters in their names.
Zino2 does not take this into account and only uses lowercase parameter names

This makes the original x11 ritz client crash because it is case-sensitive on its parameter names.
This is identified for the following parameters:
BGP:

• bgpAS
• bgpOS
• remote-AS

BFD:

• Neigh-rDNS
• bfdAddr
• bfdDiscr
• bfdIx
• bfdState

PR #335 is tested with the x11 tcl ritz client and seems to work fine
