Review request for Asterisk Developers and Olle E Johansson.


The chan_sip get_msg_text was a bit of a mess:
- it contained strlen(buf) where buf was always terminated on 0
- it reserved 5 bytes for the buffer for who knows what
- it decremented the allowed size by more than needed if addnewline was off
- the addnewline parameter was a misnomer -- and imho the wrong fix to a problem
- the \brief docs referred to a SIP MESSAGE, but it was used to get any sip request body

I did the following:
- I fixed the doxygen docs
- looked over the numbers in get_msg_text() so buf is always filled to the brim if too small
- removed the addnewline parameter that Olle added in r116240
- instead, I stripped all trailing newlines in the function that needed it

I believe r116240 was the wrong fix for the problem of trailing newlines: if the content is text/plain, newlines should certainly be allowed. Unless they're somehow used for folding the text/plain body -- which I haven't found any docs about -- removing them could cause linefeed separated text to be incorrectly joined.

(This is not an important issue at all.. but this review is here to clean up the patch in r1533.)

This addresses bug ASTERISK-18389.
