Summary:                    [patch] SIP_BODY function to get a body part of a
SIP message
Description: 
this patch adds the function SIP_BODY for chan_sip to get a body part by
its Content-Type. Therefore, the existing find_sdp() is generalized to
find_content() and find_sdp() calls find_content() with the parameter
"application/sdp". 

usage example: ${SIP_BODY(application/pidf+xml)} to get a PIDF document
from the SIP body.

---------------------------------------------------------------------- 
Please not! The function is a generic to fetch any content type from body
(or multipart body) - not only SDP. 

In fact, probably the function is most used to fetch other content types
from the body. For example we use it to get and process the PIDF-LO out of
the INVITE - this is for example necessary for processing of the emergency
calls (see IETF's ECRIT architecture for more details)

Thus, please do not rename it to something the function is not used for.
The function is used to fetch a certain content type out of the BODY of SIP
INVITEs. As the function is only useful for SIP channels, and by no means
limited to SDP, I suggest to use the name SIP_BODY.
