** See Bug #37329.
* e-mktemp.c (get_dir): setup a comjpile time option for storing
in the homedir, and also just use the uid as the key for a /tmp
dir option.
(e_mktemp_cleanup): removed entirely.
(e_mkstemp, e_mkdtemp, e_mktemp): dont save the file/dirname in a
list anymore.
(expire_dir_rec): expire old temp data from previous runs/old data
lying around. Based on access time.
(get_dir): run an expirey every now and then.
