Test for file content (-s) rather than just existance (-f). This fixes a
bug that manifests itself in the case of an empty -revoked file. A zero
element 'keys' array would be passed to gpg, forcing it to list and,
subsequently, revoke all known keys.
Bug introduced in d1240f67ea.

This requires an ugly amount of reworking of how pacman-key handles
options. The change simply to avoid passing keys, files, and directories
as arguments to options, but to leave them as arguments to the overall
program. This is reasonable since pacman-key limits the user to
essentially one operation per invocation (like pacman).
Since we now pass around the positional parameters to the various
operations, we can add some better sanity checking. Each operation is
responsible for testing input and making sure it can operate properly,
otherwise it throws an error and exits.
The doc is updated to reflect this, and uses similar verbiage as pacman,
describing the non-option arguments now passed to pacman-key as targets.
Similar to the doc, --help is reorganized to separate operations and
options and remove argument tokens from operations.

This was really only half a fix for FS#28445, as it still doesn't
correctly handle the case of filenames with spaces. In the short term,
there is no obvious fix for this. In the long term, I believe the
correct decision is to rewrite the options parser to be more in line
with GNU getopt_long.

We cannot rely on gpg's exit code. Instead we have to check the status-fd to
figure out whether a signature is valid or not.
In addition to this pacman-key --verify can now be used in scripts as it will
return an exit code of 1 if the signature is invalid.

This addresses two problems:
1) echo's behavior is inconsistent when dealing with flags, and can
potentially be problematic.
$ echo -n
$ echo -- -n
-- -n
2) Always using the end of options markers prevents translated strings
from throwing errors, as shown in FS#28069.
The remaining "inconsistencies" are because printf is being used in a
guaranteed safe manner, e.g.
printf '%s\n' "$(gettext "--this can never break")"

Return codes from gpg commands are currently lost. This adds the functionality
of taking non-zero exit statuses from gpg. This includes error reporting for all
gpg commands that are run individually, run in a loop, and run through a pipe.
Includes the check_keyids_exist function which verifies a key exists locally
prior to attempted local manipulation of the key.
If a gpg command has a non-zero status, pacman-key will now exit with a non-zero
status. It will print a gettext error message of gpg's failure.

Adds functions for every gpg command. By pulling out the gpg commands from the
"program start" section, additional commands can be run before or after a
specific gpg command without adding additional clutter to the function call
section.
Adds an explicit exit status of 0 to prevent arithmetic expansions from
returning non-zero, thereby falsely causing pacman-key to have a non-zero exit
status.
This change creates the framework for additional error messages and better
exit statuses being added to every pacman-key gpg call.

The default is supposidely 30 seconds from the gpg manpage, but that
sure wasn't what I was seeing- it was somewhere closer to two minutes of
silence. Add a more reasonable 10 second timeout value which should be
good enough for any keyserver that doesn't totally stink at it's job.

This allows it to serve double-duty. In order to allow users to base
verification decisions off of both a valid signature and a trusted
signature, we need to assign some level of owner trust to the keys we
designate as trusted on import.

* --import now only imports keys from pubkey.gpg and does not import
owner trust; if you want to have both simply run the operations in
sequence.
* --import-trustdb has been simplified; it will overwrite existing
values in the trust database as before, but there is no need to export
it first as those values are safe if left untouched.
* Fix the manpage referring to a non-existent option.

We're ill equipped to be using this flag as we don't trap and respond to
the ERR signal. The result is that if is ever tripped, pacman-key will
instantly exit with no indication of why. At the same time, we're
already fairly good about doing our own error checking and verbalizing
it before dying.

This is similar to the 'foo-revoked' file we had. This will be used to
inform the user what keys in the shipped keyring need to be explicitly
trusted by the user.
A distro such as Arch will likely have 3-4 master keys listed in this
trusted file, but an additional 25 developer keys present in the keyring
that the user shouldn't have to directly sign.
We use this list to prompt the user to sign the keys locally. If the key
is already signed locally gpg will print a bit of junk but will continue
without pestering the user.

We're putting the cart ahead of the horse a bit here. Given that our
keyring is not one where everything is implicitly trusted (ala gpgv),
keeping or deleting a key has no bearing on its trusted status, only
whether we can actually verify things signed by said key.
If we need to address this down the road, we can find a solution that
works for the problem at hand rather than trying to solve it now before
signing is even widespread.

Unlike our protégé apt-key, removing a key from our keyring is not
sufficient to prevent it from being trusted or used for verification. We
are better off flagging it as disabled and leaving it in the keyring so
it cannot be reimported or fetched at a later date from a keyserver and
continue to be used.
Implement the logic to disable the key instead of delete it, figuring
out --command-fd in the process.
Note that the surefire way to disable a key involves including said key
in the keyring package, such that it is both in foobar.gpg and
foobar-revoked.
