Iksemel

* Build system migrated to meson
* Python bindings now can compaliable with python3.x versions.
* OpenSSL 1.1.x support for jabber

* You can now use OpenSSL or GNUTLS as the TLS back-end (compile time option).
* Python bindings. You can use iksemel from Python as an XMPP client library
or as a very fast and memory efficient XML parser.

* Some previously rejected valid UTF8 sequences are now accepted.
* Whitespace is allowed between attribute name, equal sign and value.
* Small fixes all around (see ChangeLog).

* Project is moved to
http://code.google.com/p/iksemel/
there is also a new mailing list at:
http://groups.google.com/group/iksemel
Please use those instead of old jabberstudio.org addresses.
* iksemel is now participating in Coverity Inc's free software
quality improvement program (http://scan.coverity.com). As a
first result, a few problems found by Coverity's static analysis
tool in the iks_sasl_challenge() are fixed in this release, and
other than that, iksemel passes from defect test with no problems.
* Extra padding problem in the base64 encoder is fixed. Some servers
were having problems with extra '=' padded SASL digests.
* New dom functions: iks_append(), iks_prepend(), iks_append_cdata(),
iks_prepend_cdata(). You can append/prepend new nodes within the
siblings with them, insert_ functions were only appending at the
last child. Thus editing a tree is much easier now.
* iks_load was giving error on files with multiply of 4Kb sizes, fixed.

* SASL authentication.
* SSH connections via gnutls library.
* Socket code abstracted, you can even provide your own transport functions.
* Compiles on Windows with MinGW.
* iks_sha_print() uses lowercase hex numbers to comply with latest jabber.
* New stack implementation, much faster and uses less memory.
Unfortunately API has changed a bit:
iks_stack_strcat, strcatv, print functions removed.
iks_stack_stats modified.
iks_stack_strecat renamed to iks_stack_strcat.
iks_stack_new takes two chunk sizes, one for structures one for strings.
iks_stack_strdup returns (char *).

* Minor sax parser speed up.
* iks_string() and dom parser performance is improved greatly.
* iksperf: new tool for measuring iksemel performance.
* ikslint: better error checking. supports stdin. can display tag usage histogram.
* New dom functions: iks_copy(), iks_copy_within(), iks_root(), iks_tree().
* License of the documentation changed to GPL from GNU FDL.
