If seconds are not specified in the string to be parsed, they're not
set according to the reference time (in the no rounding case) nor
rounded properly (in the rounding up cases). Fix this.
The bug caused searches such as date:10:30..10:30 to match messages
with date exactly 10:30:00 only, and not in range 10:30:00..10:30:59
(inclusive) as documented.
Note that date searches referring "noon" or "5pm" will still be
interpreted as exact to the second.
The timegm(3) function is a non-standard extension to libc which is
available in GNU libc and on some BSDs. Although SunOS had this
function in its libc, Solaris (unfortunately) removed it. This patch
implements a very simple version of timegm() which is good enough for
parse-time-string.c.

Add a date/time parser to notmuch, to be used for adding date range
query support for notmuch lib later on. Add the parser to a directory
of its own to make it independent of the rest of the notmuch code
base.
