* src/libical/icalrecur.c: merged in some new stuff from libical CVS.
(icalrecur_add_byrules): If no sign is given set sign to 1 (i.e.
default to positive).
(icalrecur_iterator_new): when setting up the year days array, handle
the case where a year has no occurrences and we have to skip it.
Also initialize the last.day and last.month fields.
(expand_by_day): set the last day of the year explicitly rather than
adding 1 to year and subtracting 1 from day. It is more efficient,
and less prone to bugs. Also rewrote a bit.
(expand_year_days): added code to handle BY_MONTH_DAY and BY_DAY +
BY_MONTH_DAY, and rewrote code to handle BY_DAY + BY_MONTH.
(next_year): handled the case where there are no occurrences in the
year.
* src/libical/icaltime.c (icaltime_adjust): new function to adjust a
time by a number of days/hours/minutes/seconds.
(icaltime_day_of_week): rewrote using a single call to mktime().
(icaltime_day_of_year): rewrote using a single call to mktime().
(icaltime_from_day_of_year): rewrote in a simpler way. The old version
had a bug in it.
* src/libical/icaltime.h (struct icaltimetype): added is_daylight
flag, so we can try to distinguish between standard and daylight time
when the clocks go back. Though this doesn't always resolve the
ambiguity.
* src/libical/icalcomponent.c: added some stuff to handle timezone
data connected to the calendar component. Unfinished.
* src/libical/icalyacc.y: merged in a fix from sourceforge CVS version
of libical, so we can handle -ve UTC offsets.
* src/libical/Makefile.am (CPPFLAGS): added PACKAGE_DATA_DIR define
for finding the VTIMEZONE files.
(libical_la_SOURCES): added icalarray.[hc] and icaltimezone.[hc].
(COMBINEDHEADERS): added icalarray.h and icaltimezone.h to the headers
to be combined into ical.h.
