changes:
* fix a potential mem leak content_type and osip_message_parse.
* fix osip_body_clone method (add terminating NULL)
* fix for binary support when multipart is used.
* automatic check for reliable protocol SCTP and TLS.
* avoid <winsock.h> inclusion so user can (and must) now include either
<winsock.h> or <winsock2.h> before including <osip/osip2.h>
changes:
* remove #ifdef OSIP_RETRANSMIT_2XX to always compile it.
* initialize remote_contact_uri when dialog is built with notify.
* allow very short attachements.
* new macros allocators.
* remove use of alloca in the parser.
* fix memory bug when realloc is needed on large message.
* remove useless prototypes.
* fix memory access in parser.
* API slightly broken to enable support for binary data.
* improvements of the sip message test suite.
The binary compatibility and API compatibility has been lost
oSIP is an implementation of SIP.
The GNU oSIP library is written in C and get no dependencies except the
standard C library. oSIP is thread safe and will generally be used in a
multi-threaded application. Nevertheless, this is optional.
oSIP is little in size and code and thus could be use to implement IP
soft-phone as well as embedded SIP software. oSIP is not limited to
endpoint agents, and can also be used to implement "SIP proxy".
oSIP does not intend to provide a high layer API for controlling
"SIP Session" at this step. Instead, it currently provides an API for the
SIP message parser, SDP message parser, and library to handle
"SIP transactions" as defined by the SIP document.
