When building tests, compat needs to be built. Do this prior to running any tests. This ensures tests can be run from a clean tree. Furthermore, add got_compat.h to all test headers. This wasn't necessary before as this was implicitly being included, but now isn't.

Simply the SHA detection by not predicating on libcrypto, but instead checking individual header files.

Remove sha1.h as this is found portably across systems.

It will soon grow functions to deal with sha256 too. stsp@ agrees.

In preparation for wide sha256 support; stsp@ agrees. Change done mechanically with find . -iname \*.[cy] -exec sam {} + X ,x/<sha1\.h>/i/\n#include <sha2.h>

Now that the handling of including sys/queue.h is better, there's no need to remove those lines from the source. Copy the location of those original sys/queue.h lines from upstream at the same line number, so as to avoid any conflicts in the future.

Throwing this into the mix for a while, we can always get rid of it again if it becomes annoying. No objections from stsp@

Enable the compilation and execution of the tests under regress/

This commit modifies the GoT main branch to be able to compile it under linux.

Same change as 16aeacf7088d, for subdirectories other than lib/

Previous default output remains when test cases are run individually. ok tracey
