Legacy authentication can expose password in plaintext. Since this is
not widely used mechanism, disable it by default. It can be enabled back
with connection option XMPP_CONN_FLAG_LEGACY_AUTH.
xmpp_conn_t object can be reused with saving user's handlers.
However, saving system handlers can lead to a fail during connection
process. This is because old object may contain timed handlers for
missed features or other handlers that would handle incoming stanzas
incorrectly.
the C standard says that you're not allowed to cast a function pointer to
something else
6.3.2.3 §8:
A pointer to a function of one type may be converted to a pointer
to a function of another type and back again
This function is similar to xmpp_connect_client(), but doesn't perform
authentication. Instead, it calls user's connection handler immediately
after establishing the connection. Hence, user can implement own
authendication or registration procedures.
Such a "raw" connection can be useful when user interaction is required
(e.g. Data Forms in XEP-0077, OAuth2).
Store keepalive parameters in conn object. This allows call the function
with a disconnected conn. Also, the parameters are not cleared on
reconnect and applied once a socket is created.
xmpp_conn_set_flags() and xmpp_conn_get_flags() unify interface of
connection configuration.
This interface allows compile-time check of supported features or even
run-time check. Therefore, applications can be built with older
libstrophe which doesn't support some optional flags.
This pseudo-random number generator solves problem with
platform-independent generation of randomized nonces.
Current implementation uses weak entropy, especially when
kernel.randomize_va_space = 0. But it can be improved by
adding new sources to xmpp_rand_reseed().
New internal API introduced:
xmpp_rand_new
xmpp_rand_free
xmpp_rand
xmpp_rand_bytes
xmpp_rand_nonce
expat is still the default parser, but libxml2 can also be used
via an option to the configure script. New parsers can easily be
added by implementing a parser_foo.c that uses the interface defined
in parser.h.
Some other APIs, like xmpp_stanza_to_text, return a point that must be freed by the caller with this API.

problems between Win32 (with its broken implementation) and the standard
stdio API. Also fixed a bug in debug output where long messages got
truncated to 1023 chars, and in xmpp_stanza_to_text where long stanzas
got truncated by one character.
