(cherry picked from commit 7ba8e5f376)
If an email address is specified, we use --locate-key to look up the key
using WKD and keyserver as a fallback. If the key is specified as a key
ID, this doesn't work, so we use the normal keyserver-based --recv-keys.
Note that --refresh-keys still uses the keyservers exclusively for
refreshing, though the situation might potentially be improved in a new
version of GnuPG:

There is no good reason to bloat the keyring by importing tons of
signatures we cannot use; drop any signatures that don't validate
against another available key (probably the master keys).
If any desired signatures get cleaned, the key can be refreshed after
importing the new signing public key.

By default, the latest versions of GnuPG disable the Web of Trust and
refuse to import signatures from public keyservers. This is to prevent
denial of service attacks, because refusing to import signatures only if
the key size is too big, is apparently too silly to consider.
Either way, pacman needs the WoT. If pacman imports a key at all, it
means everything failed and we are in fallback mode, trying to overcome
a shortcoming in the availability of keys in the keyring package.
(This commonly means the user needs to acquire a new key during the same
transaction that updates archlinux-keyring.)
In order for that new key to be usable, it *must* also import signatures
from the Master Keys.
I don't give credence to this supposed DoS, since the worst case
scenario is nothing happening and needing to CTRL+C in order to exit the
program. In the case of pacman, this is better than being unable to
install anything at all (which is gnupg doing a much more harmful DoS to
pacman), and in the already unusual case where something like
--refresh-keys is being used directly instead of depending on the
keyring package itself, gnupg supports WKD out of the box and will
prefer that for people whose keys are marketed as being non-DOSable.

If an option is a two-part option, we print both (separated by IFS=' '),
but when grepping to see if it already exists, we only checked the first
component. This means that something like keyserver-options could only
check if there were existing keyserver options of any sort, but not
which ones.

Simply pass options on to gpg the same way gpg uses them -- no looping
through and checking lots of signatures.
This prevents a situation where the signature file to be verified is
manipulated to contain an embedded signature which is valid, but not a
detached signature for the file you are actually trying to verify.
gpg does not offer an option to verify many files at once by naming each
signature/file pair, and there's no reason for us to do so either, since
it would be quite tiresome to do so.
In the event that there is no signature/file pair specified to
pacman-key itself,
- preserve gpg's behavior, *if* the matching file does not exist, by
- assuming the signature is an embedded signature
- deviate from gpg's behavior, by
- offering a security warning about which one is happening
- when there is an embedded signature *and* a matching detached file,
assume the latter is desired

Many of these are pointless (e.g. there is no need to explicitly turn on

The only useful modelines are the ones enforcing the project coding
standards for indentation style (and "maybe" filetype/syntax, but
everything except the asciidoc manpages and makepkg.conf is already

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.
