merge in ics-mr1-release history after reset to ics-mr1

Update to tzdata2011n.
There are three changes of note - most urgently, Cuba (America/Havana) has extended summer time by two weeks, now to end on Nov 13, rather than the (already past) Oct 30. Second, the Pridnestrovian Moldavian Republic (Europe/Tiraspol) decided not to split from the rest of Moldova after all, and consequently that zone has been removed (again) and reinstated in the "backward" file as a link to Europe/Chisinau. And third, the end date for Fiji's summer time this summer was moved forward from the earlier planned Feb 26, to Jan 22. Apart from that, Moldova (MD) returns to a single entry in zone.tab (and the incorrect syntax that was in the 2011m version of that file is so fixed - it would have been fixed in a different way had this change not happened - that's the "missing" sccs version id). Bug: 5863692 Change-Id: I78e29c682c623b1dec0b0ea2cb6545713ae9eed0

- *

- *       1 -  3	f4		fp register 4
- *	 4 -  6	f5		fp register 5

- * The magic number number identifies the jmp_buf and
- * how the buffer was created as well as providing
- * a sanity check
- *
- * A side note I should mention - Please do not tamper
- * with the floating point fields. While they are
- * always saved and restored at the moment this cannot
- * be garenteed especially if the compiler happens
- * to be generating soft-float code so no fp
- * registers will be used.
- *
- * Whilst this can be seen an encouraging people to
- * use the setjmp buffer in this way I think that it
- * is for the best then if changes occur compiles will
- * break rather than just having new builds falling over
- * mysteriously.
+ * This value comes from the original OpenBSD ARM-specific header
+ * that was replaced by this one.
