Create sha256 and sha512 modules and move files into gl/.

* bootstrap.conf (gnulib_modules): Add sha256 and sha512.
* m4/prereq.m4: Don't require gl_SHA256 or gl_SHA512.
* gl/modules/sha512: New file.
* gl/modules/sha256: New file.
* m4/sha256.m4: Move to ...
* gl/m4/sha256.m4: ...here, removing use of AC_SOURCES.
* m4/sha512.m4: Move to ...
* gl/m4/sha512.m4: ...here, removing use of AC_SOURCES.
* lib/sha256.c, lib/sha256.h: Move to ...
* gl/lib/sha256.c, gl/lib/sha256.h: ...here.
* lib/sha512.c, lib/sha512.h: Move to ...
* gl/lib/sha512.c, gl/lib/sha512.h: ...here.
* lib/u64.h: Move to ...
* gl/lib/u64.h: ...here.
