libabis: ipaccess: conclude new ipaccess_send_*() functions and use them

This patch finishes the new ipaccess_send_*() functions and use them
in the ipaccess-proxy code.

I have also cleanup the definition of the PONG, ID_ACK and ID_REQ
messages (including some minor documentation about them).

I had to rename ipaccess_recvmsg() in ipaccess-proxy to avoid clashing
with the one defined in libabis.
