Fix deprecated function wrapping
Merge pull request #2310 from mdboom/tests/how-to-skip-all-doctests

Include an example of how to skip all doctests in a module
sip_pix2foc should subtract crpix and the end, and sip_foc2pix should do
the inverse.
Add an example.  Closes #1957 and supersedes #1959.
Workaround for #1953.  The BinTableHDU constructor handles data that is not already in FITS native format poorly.  FITS_rec.from_columns, on the other hand, does.  So go through that first.
some cleanup in io/ascii/tests

Some of the tests still had import ... as asciitable as a heritage
from the old asciitable package. Similarly, there was some
require_numpy from times when asciitable worked without numpy.
Nothing important, but hey, why not fix that when I am sitting at a
bus station anyway.
