Reflected messages can't be filtered by nick only otherwise you might
ignore messages comming from you on another devices.
Consequently we maintain a list of sent messages id in mucwin.
To be sure the id will be correctly reflected we use the origin-id
stanza.
Store hints are required has some server might discard messages without
body. Here we ensure OMEMO messages are stored on server and delivered
to client when they connect back.
It's really important since it avoid libsignal to desynchronize
counters.
We try to decrypt all messages, if it's successful we use
sv_ev_incoming_message even for OMEMO messages. We pass an OMEMO
boolean to let UI be aware that message were encrypted.
With all the different kinds of encryption (OMEMO, OTR3 OTR4, PGP in XEP-0027 and XEP-0373) it might be helpful to know which kind of encryption is used.
create_unique_id() was changed to use UUIDs instead of a counter in the
last commit. Since now it depends on connection_create_uuid() which is
in the xmpp subfolder the function should also be moved there.
Renamed it to connection_create_stanza_id() and moved it to
src/xmpp/connection.c.

In most get-like funcitons libstrophe returns pointer to a string
that resides in an internal structure (e.g. xmpp_stanza_t). Hence,
Profanity must not change such strings. Define respective variables
as 'const char*' to reduce a chance of error and conform future
libstrophe's interface.
This patch mostly replaces 'char *' with 'const char*', but also
fixes two memory leaks after stanza_get_reason(). Add comment within
stanza_get_reason() to fix conflict with different allocator types.
