This ensures we are actually making correct use of the information gpgme
is returning to us. Marginal being allowed was obvious before, but
Unknown should deal with trust level, and not the presence or lack
thereof of a public key to validate the signature with.
Return status and validity information in two separate values so check
methods and the frontend can use them independently. For now, we treat
expired keys as valid, while expired signatures are invalid.

This accomplishes quite a few things with one rather invasive change.
1. Iteration is much more performant, due to a reduction in pointer
chasing and linear item access.
2. Data structures are smaller- we no longer have the overhead of the
linked list as the file struts are now laid out consecutively in
memory.
3. Memory allocation has been massively reworked. Before, we would
allocate three different pieces of memory per file item- the list
struct, the file struct, and the copied filename. What this resulted
in was massive fragmentation of memory when loading filelists since
the memory allocator had to leave holes all over the place. The new
situation here now removes the need for any list item allocation;
allocates the file structs in contiguous memory (and reallocs as
necessary), leaving only the strings as individually allocated. Tests
using valgrind (massif) show some pretty significant memory
reductions on the worst case `pacman -Ql > /dev/null` (366387 files
on my machine):
Before:
Peak heap: 54,416,024 B
Useful heap: 36,840,692 B
Extra heap: 17,575,332 B
After:
Peak heap: 38,004,352 B
Useful heap: 28,101,347 B
Extra heap: 9,903,005 B
Several small helper methods have been introduced, including a list to
array conversion helper as well as a filelist merge sort that works
directly on arrays.

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.

Show output in -Qip for each package signature, which includes the UID
string from the key ("Joe User <joe@example.com>") and the validity of
said key. Example output:
Signatures : Valid signature from "Dan McGee <dpmcgee@gmail.com>"
Unknown signature from "<Key Unknown>"
Invalid signature from "Dan McGee <dpmcgee@gmail.com>"
Also add a backend alpm_sigresult_cleanup() function since memory
allocation took place on this object, and we need some way of freeing
it.

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.

This allows us to capture size and mode data when building filelists
from package files. Future patches will take advantage of this newly
available information, and frontends can use it as well.

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 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.

This allows us to separate the name and hash elements in one place and
not scatter different parsing code all over the place, including both
the frontend and backend.

This removes the need to write accessor methods for every type we have,
and simplifies the API. Any type that doesn't need magic* can be
converted in this fashion to make it easier for frontend applications to
use, as well as make it less of a pain to introduce new such structs in
the future.
* "magic" meaning something like pmpkg_t where values can be lazy loaded.

This is more in line with reality and what we have our makepkg, etc.

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.
