…ports.

Some time ago Jasper Lievisse Adriaanse imported libcdio into OpenBSD
ports including with a dedicated OpenBSD backend:

https://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/audio/libcdio/files/openbsd.c?rev=1.4&content-type=text/x-cvsweb-markup

This change merges his work into the existing NetBSD backend (there were
many missing functions in the NetBSD backend).

Note that in doing so, we also switched from LBA addressing to MSF
addressing.

Fixes many problems with the NetBSD driver on OpenBSD.

- Add write and exclusive-write CD access modes
- add netbsd mode1 reading like others

From Stef:
I came up with a patch that I believe will work for everyone.
It uses AC_SEARCH_LIBS, instead of AC_CHECK_LIB. So, if keypad() is
defined in -lncurses or -lcurses, it does exactly what it does
now. However, if -ltinfo is needed, it is added to CDDA_PLAYER_LIBS
along with the curses library.

Remove read-disc-struct binary

thanks to Thomas for pointing out.

Try using Doxygen better. BTW it now supports markdown.

The latest MinGW32 reports the following during compilation:

image/bincue.c: In function 'cdio_get_devices_bincue':
image/bincue.c:992:20: warning: inlining failed in call to 'Win32Glob.constprop': call is unlikely and code size would grow [-Winline]
 static inline void Win32Glob(const char* pattern, const char* szCurPath, char ***drives, unsigned int *num_files)
                    ^~~~~~~~~

…ses, or immediate memory fault with language codes above 0x2B.

…ed it to API

* Done so that libcdio doesn't bail out when processing non-compliant
  ISOs such as openSUSE Leap 15.0

* And silence the warning in case of little-endian and big-endian mismatch
* Also introduce a from_723_with_err() that can be used to report mismatch
  if needed
