- proftest: declare the _mkdir_recursive loop index inside the for.
- xmpp/presence: shorten the resource-snapshot comment to one line.
- command/cmd_funcs: report the /vcard remove index error via cons_show_error.
- common: replace g_assert in g_diff_to_gsize with a log_error + return 0
(moved out of the header into common.c); take get_random_string length as
size_t instead of asserting non-negative.
- otr: drop the change-narrating comment on the whitespace memmove.
