ARI/AMI: Include language in standard channel snapshot output

The channel "language" was already part of a channel snapshot, however is was
not sent out over AMI or ARI. This patch makes it so the channel "language" is
included in the appropriate AMI or ARI events.

core: avoid possible asterisk -r crash from long id

When connecting to the remote console, an id string
is first provided that consts of the hostname, pid,
and version.  This is parsed by the remote instance
using a buffer that may be too short, and can allow
a buffer overrun because it is not terminated. This
patch adds termination and a larger buffer.
