Requiored for astropy 7.2
- Update to 8.5
## C library
* In linp2x(), quarantine NaN elements of the pixel coordinate
vector from infecting non-NaN elements in the case where the
PCij matrix is diagonal (noting that zero * NaN = NaN).
Likewise in linx2p(). Reported by Thomas Robitaille with patch.
* Quelled nuisance compiler warnings in wcspih() and wcsbth().
- WCSLIB version 8.4
## C library
* Fixed some problems in wcs_chksum() and changed
wcs_fletcher32() to conform to the standard computation.
* New test program, twcs_pthread.
- WCSLIB version 8.3
## C library
* Until now, wcsset() always operated unconditionally - the
wcsprm struct was set or reset regardless of its current state.
Likewise the various *set() functions for the other structs.
However, in some situations, particularly in threaded
applications, it is desirable to have wcsset(), etc., check the
state of the struct and return immediately if it has already
been set. This may now be accomplished by setting wcsprm::flag
== 1 (instead of 0) before calling wcsset(). Likewise for the
other structs. This sets a "bypass" flag within the struct
itself.
* A new function, wcsenq(), queries the state of the wcsprm
struct, specifically whether WCSLIB is managing its memory,
whether the struct has been set, whether or not it is in bypass
mode, and whether it is self-consistent. There are
corresponding functions for the other structs: celenq(),
disenq(), linenq(), prjenq(), spcenq(), and tabenq(). Please
