proposed time zone package changes for Samoa (comments), Bangladesh, and Pakistan

At the end of this message are proposed changes to time zone files, summarized here:
	asia
		Bangladesh	does not go off DST in 2009
		Pakistan	Goes off DST November 1 2009 (and in future years)
	australasia
		Samoa		information on Samoa NOT starting DST in 2009 (comments only)
I've only included changes involving 2009; other data changes (as well as tz-art additions) are
in the pipeline.

The adoption of "permanent" DST in Bangladesh means there's another place that can't be
represented by a POSIX time zone environment variable; this may cause some grief.
We may want to change the trailing...
			6:00	1:00	BDST
...line for Bangladesh to...
			5:00	-	BDST
...either in the short term or the long term.

If no one finds problems, expect these changes to show up on the ftp site on 2009-10-19.

! # Arbitrarily end DST at the end of 2009 so that a POSIX-sytle time zone string
! # can appear in the Dhaka binary file and for the benefit of old glibc
! # reimplementations of the time zone software that mishandle permanent DST.
! # A change will be required once the end date is known.
