The precedence goes as follows: signature > sha256sum > md5sum
Add some logic and helper methods to check what we have available when
loading a package, and then only check what is necessary to verify the
package. This should speed up sync database verifies as we no longer
will be doing both a checksum and a signature validation.

We did this with depends way back in commit c244cfecf654d3 in 2007. We
can do it with these fields as well.
Of note is the inclusion of provides even though only '=' is supported-
we'll parse other things, but no guarantees are given as to behavior,
which is more or less similar to before since we only looked for the
equals sign.
Also of note is the non-inclusion of optdepends; this will likely be
resolved down the road.
The biggest benefactors of this change will be the resolving code that
formerly had to parse and reparse several of these fields; it only
happens once now at load time. This does lead to the disadvantage that
we will now always be parsing this information up front even if we never
need it in the split form, but as these are uncommon fields and our
parser is quite efficient it shouldn't be a big concern.

As noted by Allan, we failed pretty hard if gpgme was compiled out. With
these changes, only sign001.py fails. This can/will be fixed later once
we beef up the test suite with more signing tests anyway.

This can only ever operate on the local database, and a local package at
that. Change the function signature to take a handle and package object,
add the relevant asserts, and ensure the frontend can detect the package
not found condition when finding packages to pass to this method.

This gives us more granularity than the former Never/Optional/Always
trifecta. The frontend still uses these values temporarily but that will
be changed in a future patch.
* Use 'siglevel' consistenly in method names, 'level' as variable name
* The level becomes an enum bitmask value for flexibility
* Signature check methods now return a array of status codes rather than
a simple integer success/failure value. This allows callers to
determine whether things such as an unknown signature are valid.
* Specific signature error codes mostly disappear in favor of the above
returned status code; pm_errno is now set only to PKG_INVALID_SIG or
DB_INVALID_SIG as appropriate.

The following function renames take place for the same reasoning as
the previous commit:
_alpm_grp_new -> _alpm_group_new
_alpm_grp_free -> _alpm_group_free
_alpm_db_free_grpcache -> _alpm_db_free_groupcache
_alpm_db_get_grpfromcache -> _alpm_db_get_groupfromcache

Using grp instead of group is a small saving at the cost of clarity.
Rename the following functions:
alpm_option_get_ignoregrps -> alpm_option_get_ignoregroups
alpm_option_add_ignoregrp -> alpm_option_add_ignoregroup
alpm_option_set_ignoregrps -> alpm_option_set_ignoregroups
alpm_option_remove_ignoregrp -> alpm_option_remove_ignoregroup
alpm_db_readgrp -> alpm_db_readgroup
alpm_db_get_grpcache -> alpm_db_get_groupcache
alpm_find_grp_pkgs -> alpm_find_group_pkgs

Start by converting all of our flags to a 'status' bitmask (pkgcache
status, grpcache status). Add a new 'valid' flag as well. This will let
us keep track if the database itself has been marked valid in whatever
fashion.
For local databases at the moment we ensure there are no depends files;
for sync databases we ensure the PGP signature is valid if
required/requested. The loading of the pkgcache is prohibited if the
database is invalid.

This is another step toward doing both local database validation
(ensuring we don't have depends files) and sync database validation (via
signatures if present) when the database is registered.

This is the ideal place to do it as all clients should be checking the
return value and ensuring there are no errors. This is similar to
pkg_load().
We also add an additional step of validation after we download a new
database; a subsequent '-y' operation can potentially invalidate the
original check at registration time.
Note that this implementation is still a bit naive; if a signature is
invalid it is currently impossible to refresh and re-download the file
without manually deleting it first. Similarly, if one downloads a
database and the check fails, the database object is still there and can
be used. These shortcomings will be addressed in a future commit.

We didn't do due diligence before and ensure prior pm_errno values
weren't influencing what happened in further ALPM calls. I observed one
case of early setup code setting pm_errno to PM_ERR_WRONG_ARGS and that
flag persisting the entire time we were calling library code.
Add a new CHECK_HANDLE() macro that does two things: 1) ensures the
handle variable passed to it is non-NULL and 2) clears any existing
pm_errno flag set on the handle. This macro can replace many places we
used the ASSERT(handle != NULL, ...) pattern before.
Several other other places only need a simple 'set to zero' of the
pm_errno field.

This method is old, it doesn't adequately check for a NULL server list,
and can easily be done using better API method we provide these days.
All former users of this method can get similar results by calling
alpm_db_get_servers() and using the data from the returned server list.

Note that is a bit different than the normal _alpm_db_path() method; the

These new method signatures return and take handle objects to operate on
so we can move away from the idea of one global handle in the API. There
is also another important change and that deals with the setting of root
and dbpaths. These are now done at initialization time instead of using
setter methods. This allows the library to operate more safely knowing
that paths won't change underneath it.

The usefulness of this is rather limited due to it not being compiled
into production builds. When you do choose to see the output, it is
often overwhelming and not helpful. The best bet is to use a debugger
and/or well-placed fprintf() statements.

Currently we have one call that has all sorts of crazy behavior and doesn't
make a whole lot of sense. Go from one method to the normal four methods we
have for all of our other lists we use in the library to make it a lot
easier for a frontend to manipulate server lists.
