MFV of tzcode2009e:

Upgrade of the tzcode from 2004a to 2009e.

Changes are numerous, but include...

- New format of the output of zic, which supports both 32 and 64
bit time_t formats.

- zdump on 64 bit platforms will actually produce some output instead
of doing nothing for a looooooooong time.

- linux_base-fX, with X >= at least 8, will work without problems related
to the local time again.

The original patch, based on the 2008e, has been running for a long
time on both my laptop and desktop machine and have been tested by
other people.

After the installation of this code and the running of zic(8), you
need to run tzsetup(8) again to install the new datafile.
