These files cannot be automatically relicensed by util/relicense.pl
since they either contain unusual but trivial contributions (such as
the addition of __nonnull function attributes), or contain lines
dating back to the initial git revision (and so require manual
knowledge of the code's origin).

Parsing a timeout value (specified in milliseconds) into an internal
timeout value measured in timer ticks is a common operation. Provide
a parse_timeout() value to carry out this conversion automatically.

Nothing currently prevents a menu separator from being assigned a
shortcut key, and then from being selected using that shortcut key.
This produces an inconsistency in the user interface, since separators
cannot be selected by other means of menu navigation (arrow keys, page
up/down, etc).
It would be trivial to prevent separators from being assigned shortcut
keys, but this would eliminate one potentially useful use case: having
a large menu and using shortcut keys to jump to a section within the
menu.
Fix by treating a shortcut key on a separator as equivalent to "select
the separator, then press the down arrow key". This has the effect of
moving to the first non-separator menu item following the specified
separator, which is probably the most intuitive behaviour. (The
existing logic for moving the selection already handles the various
nasty corner cases such as a menu ending with one or more separators.)

Unrecognised keys may be returned by getkey() as character code zero,
which currently matches against the first menu item with no shortcut
key defined.
Prevent this unintended behaviour by explicitly checking that the menu
item has a defined shortcut key.
