Stop symlinking, move files to intended directory
Rather than making include/openssl/foo.h a symlink to crypto/foo/foo.h, this change moves the file to include/openssl/foo.h once and for all. Likewise, move crypto/foo/footest.c to test/footest.c, instead of symlinking it there. Originally-by: Geoff Thorpe <geoff@openssl.org> Reviewed-by: Rich Salz <rsalz@openssl.org>
