Prevent debug output when loading sccp.conf containing type=line|devi…

…ce entries

Fix sccp_config / globals issue.

Because sccp_globals was using: "skinny_codec_t global_preferences[SKINNY_MAX_CAPABILITIES];"
and sccp_config was expecting assuming it would be a struct (like the ones using in sccp_device etc).
When compiling with "--enabled-video" and specifying a video codec in sccp.conf. Globals Memory would
be clobered, causing very nasty segfault later on during executation.

Synced up the struct used by globals / device / channel to all use the same format.

Fix installation of chan_sccp-en_US.xml

- Use astdatadir from /etc/asterisk/asterisk.conf if available
- Add AST_XML_DOC to config.h
- Show function/application documentation being installed

Fix: compilation error on ast113

Fix: configure.ac remnants (again)
