If not, when the session of mu is killed, these child processes are also
killed. This scenario shows up when using mu4e: a PDF attachment, for
example, is opened by Evince, but as soon as Emacs exits, Evince is also
killed.
mu_util_fputs_encode was aborting on behalf of the stack-guard on
OpenBSD (seemingly only when compile with optimization). It appears as
if the root cause of this was a differences in sizes of the parameters
to g_locale_from_utf8. Fix this.
Some users were report seeing get_uid_term high in the profiles; so
optimize this:
- make mu_util_get_hash a static inline function (used by get_uid_term)
- don't use 'realpath' in get_uid_term, seem that's the main culprit
- some slight faster string handling there too.
it seems g_locale_from_utf8 behaves a bit differently on bsd/macosx,
causing a segfault (but when run under gdb!). this code path was hit
for messages with encoding problems in non-utf8 locales
