Our error message used to be very unclear when the configuration file
could not be found:
$ ./pactree -lsr gtk
error: failed to register sync DBs
Instead, display an accurate message and include the file name:
$ ./pactree -lsr gtk
error: config file /usr/local/etc/pacman.conf could not be read
Also, move the error message inside register_syncs() to allow for
differentiating between different errors that might require a handler in
the future.

This allows for specifying an alternate configuration file path, similar
to pacman's "--config" option.
Given that there is currently no other way to tell pactree to read from
another configuration file (except for patching or symlinking), this
seems totally sensible - even if there are plans to refactor and/or
replace the standalone configuration file parser.
We do not define a short option for the sake of consistency with
pacman's set of command line options.

There are many other ways to fail a package load other than "file not
found". We should also use the correct error code in this case. Clean it
up a bit in the various callers.

There were many cases where the string coming in was a blank line, e.g.
"\n\0", length 1. The trim routine starts by trimming leading spaces,
thus trimming everything. We would then proceed to do a memmove of the
NULL byte, which is completely worthless as we can just assign it
instead.

The supposed safety blanket of this function is better handled by
explicit length checking and usages of strlen() on known NULL-terminated
strings rather than hoping things fit in a buffer. We also have no need
to fully fill a PATH_MAX length variable with NULLs every time as long
as a single terminating byte is there. Remove usages of it by using
strcpy() or memcpy() as appropriate, after doing length checks via
strlen().

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.

Only one of these looked like a real red flag, in find_requiredby(), but
it doesn't hurt to fix several of them up anyway.
Unfortunately, we can't turn this on universally due to things like the
sync(), remove(), etc. builtins which we often use as variable names.

Add a whole lot of bloat to parse pacman.conf and only a few lines to
use the list of sync DBs instead of the local DB.
Dan: I fully plan on this being temporary and us finding a better way in
the future to parse pacman.conf from multiple binaries. Adding a
standalone config parser is probably not the right way of going about
things, but for now it is by far the easiest.

Declare an alpm_list which, for now, only holds our local database.
walk_deps and walk_reverse_deps are refactored to account for this, and
a helper function is added to wrap alpm_db_get_pkg for traversing a
list.
This is groundwork for letting pactree walk the sync DBs.

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.

Both md5sum verification and PGP verification can and should be done at
package load time. This allows verification to happen as early as
possible for packages provided by filename and loaded in the frontend,
and moves more stuff out of sync_commit that doesn't really belong
there. This should also set the stage for simplified parallel loading of
packages later down the road.

This was discussed and more or less agreed upon on the mailing list. A
huge checkin, but if we just do it and let people adjust the pain will
end soon enough. Rebasing should be relatively straighforward for anyone
that sees conflicts; just be sure you use the new return style if
possible.
The following semantic patch was used to do the change, along with some
hand-massaging in order to preserve parenthesis where appropriate:

Read the package information for sync/local databases into a pmpkghash_t
structure.
Provide a alpm_db_get_pkgcache_list() method that returns the list from
the hash object. Most usages of alpm_db_get_pkgcache are converted to
this at this stage for ease of implementation. Review whether these are
better accessing the hash table directly at a later stage.
