If savelog is invoked as a normal user and asked to create files
that are not writeable (-m 0400), it will prompt during mv:

$ savelog -qm 0400 bar
mv: replace 'bar', overriding mode 0400 (r--------)?

Do not call update-mime in maintainer scripts

See merge request debian/debianutils!2

There has been a trigger for that since mime-support 3.52-1, released
in February 2012.

Closes: #719692

Use mkstemps(3) instead of tempnam(3).

See merge request debian/debianutils!1

tempnam(3) is insecure, not recommended to be used, marked as obsolete
in POSIX.1-2008. In fact, pseudo(1) fakeroot replacement for
OpenEmbedded, blocks the use of tempnam(3) and tmpnam(3) hardcoding
them to return ENOMEM.

Reimplement tempfile using mkstemps(3), performing directory selection
according to tempfile's manual page.

Update the manpage accordingly.
