Update of /usr/cvsroot/asterisk/include/asterisk
In directory mongoose.digium.com:/tmp/cvs-serv28010/include/asterisk

Modified Files:
	cdr.h pbx.h 
Log Message:
This patch adds a new api call:
int pbx_builtin_serialize_variables(struct ast_channel *chan, char *buf, size_t size);
takes a chan and a char * 'buf' assumed to be 'size' bytes.

The function fills 'buf' with a <CR>('\n') delimited list of name,value pairs in turn delimeted by '='
eg:
SIPCALLID=f30e4e72-f715193f at 1.2.3.4
SIPUSERAGENT=Sipura/SPA2000-2.0.6(c)
SIPDOMAIN=1.2.3.4

It returns the acutal number of variables encountered.
If the attempt to fill 'buf' goes beyond 'size' bytes the operation is halted and the incomplete string is returned as is.

To demonstrate a use for this, the "show channel <channame>" command has been retrofitted with the call so it also dumps all of the chan's vars
