[PATCH v3 1/4] [BZ #14161] tst-strptime2.c: add %z minute and range limit tests

[James Perkins <james at loowit dot net>]

This is part of a fix for [BZ #16141] strptime %z offset restriction.

Add tests to time/tst-strptime2.c to explicitly test the following
areas of strptime's %z input field descriptor:

1) Correct conversion for minutes portion of timezone offset string into
seconds part of the timezone offset.

* New offsets tested are +1157, +1158, and +1159.
* Two of the new offsets fail, showing that strptime incorrectly
  calculates the seconds from minutes not divisible by 3 (+1158, +1159).
* tst-strptime2 failure output is as follows:

  round 9: tm_gmtoff is 43056
  round 10: tm_gmtoff is 43128

2) Validate offset range of -1200 to +1200.

* New tests show that strptime validates the current range limits.
* New offsets tested are +1200, -1200, +1201, and -1201.
* A later patch will remove range limit testing.

	* time/strptime2.c (tests[]): Add tests for the strptime %z
	input field descriptor, specifically conversion of minutes
	to seconds and validation of offset range.
