parse_date_format(): convert a format name to an enum date_mode

Browse Source 
Factor out the code to parse --date=<format> parameter to revision
walkers into a separate function, parse_date_format().  This function
is passed a string and converts it to an enum date_format:

 - "relative"         => DATE_RELATIVE
 - "iso8601" or "iso" => DATE_ISO8601
 - "rfc2822"          => DATE_RFC2822
 - "short"            => DATE_SHORT
 - "local"            => DATE_LOCAL
 - "default"          => DATE_NORMAL

In the event that none of these strings is found, the function die()s.
