fix tag signing when the key file does not exist This should fail without creating any tag. Before, ssh-keygen(1) would print an error to stderr, but got would create an unsigned tag. ok op@

create and verify tags signed by SSH keys 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@

augment patch progress callback with hunks info; recover from errors Augment got_patch_progress_cb by providing the hunks that were applied with offset (or that failed) and the recoverable error encountered during the operation (bad status, missing file, ...) got_patch now proceeds when a file fails to be patched and exits with GOT_ERR_PATCH_FAILED if no other errors are encountered. While here, also add a test for the 'hunk applied with offset' case and shrink test_patch_dont_apply and illegal_status by taking advantage that 'got patch' doesn't stop at the first error. (And add some other cases to illegal_status too.) discussed with and ok stsp@

refactor apply_patch to support renaming files add two helper functions (schedule_add, schedule_del) and move the guts of apply_patch into a new function `patch_file'. This simplifies apply_patch and makes easier to figure out what happens. Then, drop GOT_ERR_PATCH_PATHS_DIFFER since we allow the to rename files.
