Please backport wcslib 4.24-1 (universe) from vivid

[Ole Streicher]

Please backport wcslib 4.24-1 (universe) from vivid to trusty

Reason for the backport:
========================
wcslib >=4.24 is needed to backport python-astropy 1.0.

Testing:
========
Mark off items in the checklist [X] as you test them, but please leave the checklist so that backporters can quickly evaluate the state of testing.

You can test-build the backport in your PPA with backportpackage:
$ backportpackage -u ppa:<lp username>/<ppa name> -s vivid -d trusty wcslib

* trusty:
[ ] Package builds without modification
[X] wcslib-tools installs cleanly and runs
[X] libwcs4 installs cleanly and runs
[X] wcslib-dev installs cleanly and runs
[X] wcslib-doc installs cleanly and runs

Reverse dependencies:
=====================
The following reverse-dependencies need to be tested against the new version of wcslib. For reverse-build-dependencies (-Indep), please test that the package still builds against the new wcslib. For reverse-dependencies, please test that the version of the package currently in the release still works with the new wcslib installed. Reverse- Recommends, Suggests, and Enhances don't need to be tested, and are listed for completeness-sake.
