SIPp full changelog

Automatic filenames (trace files, error files, etc..) are now created in the current working directory instead of in the directory of the scenario file. (Issue #399, reported by @sergey-safarov.)
Only validates SSL certficate if CA-file is separately specified! (PR #335, by Patrick Wildt @bluerise.)
Angle brackets < and > need to be escaped inside XML attributes. See #414. So, not regexp=" *<(sip:.*)>" but regexp=" *<(sip:.*)>".
Fix [routes] header in UAS scenario's. (Issue #262, reported by Stefan Mititelu (@smititelu).)
last_Keyword does not search in SIP body anymore (#207, reported by Zoltan).
Added PAGER by default to the extremely large sipp help output.
Removed unused RTPStream code concerning video streams. Also consolidated the rtpstream audio port usage to reuse the global [media_port] instead of the [rtpstream_audio_port]. Also the -min_rtp_port and -max_rtp_port options have been removed.

Fix lots of build issues, mainly with ncurses/curses/tinfo and openssl.
Better parsing of Contact header. (Issue #234.)
Proper retrying of media ports during startup. (Issue #276.)
