Rather than assume all dependencies are required for all programs, split them out. This will make packaging easier, as well as splitting the code to use subprojects. Note that due to the use of config.h semantics, in most cases the got_compat.h header file is now at the top of the .c file it is included in, so that it can handle the system header inclusion properly.

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.

Setting this option will cause 'got tag' to sign all created tags using the SSH key, unless overridden by the -s flag. ok stsp@

Existing configuration files will keep working for now since the old name with dashes is still recognized by the config parser.

Existing configuration files will keep working for now since the old name with dashes is still recognized by the config parser.

This adds a new -s flag to 'got tag' that specifies the signer identity (for example, a key file) of the tagger. The tag object will include a signature that validates each of the tag object headers and the tag message. Verifying these signed tags requires maintaining an allowed signers file which maps signer identities (i.e. the email address of the tagger) to SSH public keys. See ssh-keygen(1) for more details of the allowed signers file. After creating this file and providing the path to it in got.conf(5) using the allowed_signers option, tags may be verified using with 'got tag -V tag_name'. The return code will be non-zero if a signature fails to verify. ok stsp@

Some MacOS systems might not have GNU Bison installed, or have openssl installed. In such instances the host versions of those can be used, with a few tweaks around the edges to make them work. This commit addresses these by: * Relaxing a HAVE_CRYPTO check for __APPLE__, since the inclusion of the machine-specific headers isn't dependent on openssl being installed; * If the non-GNU version of bison on MacOS is being used, define any missing YY* variables, and add a compiler #warning so we log something. This also updates the CI scripts to default to the system versions of bison and removes openssl as a core dependency -- it's more likely openssl is going to be installed, so removing it here will mean we can catch the case for just the MacOS-specific failures, and the inclusion of openssl on other OSes should cover the rest.

Explicitly cast "char" to "unsigned char" when assigned to "int" to prevent sign extension from breaking comparions against EOF or passing invalid arguments to ctype functions.

Original commit message by deraadt: (unsigned) means (unsigned int) which on ptrdiff_t or size_t or other larger types really is a range reduction... Almost any cast to (unsigned) is a bug.

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

Feature requested by naddy. ok naddy, who also suggested some tweaks that will arrive shortly

yacc has been complaining about "shift/reduce conflicts" since commit 16c4be8c1cab9456f9dd0468c27f8ab73235737e Revert that change for now. Not sure how it can be done properly. In any case, allowing empty config blocks is not very important.

This is the beginning of support for naddy's suggestion to break this out similar to git. More code to come from stsp. ok stsp@

Make use of this in 'got clone' to persist -R option arguments given on the command line in the cloned repository's got.conf(5) file.
