If signature verification is needed, attempt to download a signature
file for a repo when it is updated. Return an error if unable to
download signature only when checking is mandatory, or if signature is
invalid.
TODO: At the moment the database signature is only checked on download.
Should we do anything with a database if it fails to be verified to prevent
its future usage?

Add a pmpgpsig_t struct to the database entry struct and functions for
the lazy loading of database signatures. Add a function for checking
database signatures, reusing (and generalizing) the code currently used
for checking package signatures.
TODO: The code for reading in signature files from the filesystem is
duplicated for local packages and database and needs refactoring.

Once we do this, add support for VerifySig to pactest. We just check if
the repo name contains Always, Never or Optional to determine the value
of VerifySig. The default is Never. pacman uses Always by default but
this is not suitable for pactest.

GnuPG looks for configuration files and keyrings in its home directory.
For a user, that is typically ~/.gnupg.
This patch causes pacman to use /etc/pacman.d/gnupg/ as the default
GnuPG home. One may override the default using --gpgdir on the command-line
or GPGDir in pacman's configuration file.

Add a new field to the package struct to hold PGP information and
instruct db_read to pick it up from the database. It is currently unused
internally but this is the first step.
Due to the fact that we store the PGP sig as binary data, we need to store
both the data and the length so we have a small utility struct to assist us.

The --reload command was refactored to allow a more flexible management.
There are two sets of keys that will be added, one that will be
removed and one that will be kept.
The set of keys to be kept are configured in pacman.conf, with the
option HoldKeys, with the same meaning of HoldPkgs. It can be repeated
and several values can be put in the same entry.
The new behavior allows a key to be marked for removal, but the user
can decide if that key must be kept. For example, if a developer has
a public repository, signed with his own key, that key must be added
to the HoldKeys option. If the key is marked for removal from pacman's
keyring, it will not be removed for the users that have configured
HoldKeys correctly.
There are other minor fixes, mainly in the handling of --add command
when there is no aditional parameter. In that case, pacman-key will
behave just like gpg, adding the contents of stdin into pacman's keyring.

This is intended to verify an existing signature on a database before
making further changes to it and performing updates. Rarely would you
use this without immediately resigning it via the -s/--sign option.
Instead, it is intended as a "chain of trust" operation where the
previous signature is verified to give you some sense that what you sign
off on is also safe.
Still todo: don't make changes unless the signature is not only good,
but also in the accepted list of keys.

In order to be fully secure, we can't only sign packages. We also need
to sign our repository metadata to prevent database falsification,
dependency injection, etc. Add an '-s/--sign' option that allows this
functionality, and will generate a .sig file side-by-side with the
package database.
While at it, fix the issue where a signature file would never be found
because of 'cd' madness (this needs fixing in another commit).
