ipa-proxy: add A-bis over IP generic proxy commands for VTY

This patch adds VTY commands to route IPA flows. The following
example allows to add a new route:

$ tests/./ipa_proxy_test &
<0000> ipa_proxy_test.c:74 entering main loop
$ telnet localhost 4260
ipa-proxy-test> enable
ipa-proxy-test# ipa instance input-oml bind 127.0.0.1 tcp port 8888
ipa-proxy-test# ipa instance output-oml connect 127.0.0.1 tcp port 3002
ipa-proxy-test# ipa route instance input-oml streamid 0xfe instance output-oml streamid 0xfe
ipa-proxy-test# ipa instance input-rsl bind 127.0.0.1 tcp port 8889
ipa-proxy-test# ipa instance output-rsl connect 127.0.0.1 tcp port 3003
ipa-proxy-test# ipa route instance input-rsl streamid 0xfe instance output-rsl streamid 0xfe

I'm using this to initially test this code [*].

[*] note that this requires a minor hackish patch for the
src/input/ipaccess.c driver which changes the default OML and RSL
ports to listen in 8888 and 8889 instead of the default ports,
thus, I can initially test everything from the localhost.
