security: harden untrusted-input handling (issue #148)
T02: guard the receive-path handlers that dereferenced jid_create()
without a NULL check — MUC join errors, subscribed/unsubscribed
presence and, with silence.non-roster enabled, every incoming message.
A stanza with a missing or malformed 'from' crashed the client
(REQ-INP-01)

T11: restrict /url open and /url save to http, https and aesgcm, so a
received file:, javascript: or data: URL is refused (REQ-INP-06); spawn
terminal-notifier through g_spawn_async with an argv instead of
building a shell command for system() (REQ-INP-07); apply the XEP-0359
disco gate to MAM result ids, as live stanza-ids already do
(REQ-INP-05); replace control and bidi-reordering characters in
incoming message bodies with U+FFFD before they reach the terminal, the
logs and the database, keeping LRM/RLM for legitimate RTL text
(REQ-INP-08); cover JID part-length boundaries and invalid UTF-8
(REQ-INP-02)

T10: replace strcpy/strcat/alloca and sprintf with g_strdup_printf and
g_snprintf (REQ-MEM-03); allocate the OMEMO key buffers with g_malloc
so a failed allocation cannot reach the following memcpy (REQ-MEM-04);
remove the variable-length arrays and enforce -Werror=vla. Two of them
were sized from remote input: the disco#info feature count and a chat
message word length. The flag also caught a one-past-the-end write and
a leak in the plugin autocompleter bindings (REQ-MEM-09)
