Support BSD and e2fsprogs UUID libraries alongside OSSP UUID library.
Allow the contrib/uuid-ossp extension to be built atop any one of these three popular UUID libraries. (The extension's name is now arguably a misnomer, but we'll keep it the same so as not to cause unnecessary compatibility issues for users.) We would not normally consider a change like this post-beta1, but the issue has been forced by our upgrade to autoconf 2.69, whose more rigorous header checks are causing OSSP's header files to be rejected on some platforms. It's been foreseen for some time that we'd have to move away from depending on OSSP UUID due to lack of upstream maintenance, so this is a down payment on that problem. While at it, add some simple regression tests, in hopes of catching any major incompatibilities between the three implementations. Matteo Beccati, with some further hacking by me

Historically this module depended on the OSSP UUID library, which accounts
|
||||
for the module's name. While the OSSP UUID library can still be found
|
||||
at <ulink url="http://www.ossp.org/pkg/lib/uuid/"></ulink>, it is not well
|
||||
maintained, and is becoming increasingly difficult to port to newer
|
||||
platforms. <filename>uuid-ossp</> can now be built without the OSSP
|
||||
library on some platforms. On FreeBSD, NetBSD, and some other BSD-derived
|
||||
platforms, suitable UUID creation functions are included in the
|
||||
core <filename>libc</> library. On Linux, Mac OS X, and some other
|
||||
platforms, suitable functions are provided in the <filename>libuuid</>
|
||||
library, which originally came from the <literal>e2fsprogs</> project
|
||||
(though on modern Linux it is considered part
|
||||
of <literal>util-linux-ng</>). When invoking <filename>configure</>,
|
||||
specify <option>--with-uuid=bsd</option> to use the BSD functions,
|
||||
or <option>--with-uuid=e2fs</option> to
|
||||
use <literal>e2fsprogs</>' <filename>libuuid</>, or
|
||||
<option>--with-uuid=ossp</option> to use the OSSP UUID library.
|
||||
More than one of these libraries might be available on a particular
|
||||
machine, so <filename>configure</> does not automatically choose one.
