If a sync DB is malformed and contains entries in the root of the
archive, load_pkg_for_entry will leave the 'filename' variable empty,
leading to a crash in the ensuing strcmp() calls which determine the DB
fragment being examined.
While this isn't a read error, this should be reported to the user so
that it can be addressed by the creator of the DB.

On operating systems we support, the behavior is always such that the
kernel will do the right thing as far as invalidating the file
descriptor, regardless of the eventual return value. Therefore,
potentially looping and calling close multiple times is wrong.
At best, we call close again on an invalid FD and throw a spurious EBADF
error. At worst, we might close an FD which doesn't belong to us when a
multi-threaded application opens its own file descriptor between
iterations of the loop.

On upgrades, indirect dependencies were not being detected if there was
a dependency in between them that was not part of the transaction. For
example, with the dependency chain: pkg1 -> pkg2 -> pkg3, if pkg1 and
pkg3 are being upgraded but not pkg2 pacman would not order pkg1 and
pkg3 properly.
This was particularly problematic when replacements were involved
because the replaced package(s) would be removed at the start of the
transaction. If an install script required the replacer and lacked
a direct dependency, it could fail.

Currently we make no effort to validate the %FILENAME% field in the
repo db. This allows for relative paths to be considered valid.
A carefully crafted db entry with a malicious relative path,
(e.g. `../../../../etc/passwd`) will cause pacman to to
overwrite _any_ file on the target's machine.
Add the following validation:
- doesn't start with '.'
- doesn't contain a '/'
- won't overflow PATH_MAX

Packages removed due to conflicts are always removed at the beginning of
the transaction and as such can be included in the check for whether all
owners of a directory will be removed in a transaction. Installed
versions of packages being upgraded, other than the one with the
conflict, cannot be used because our transaction ordering is not
intelligent enough to ensure that they are removed prior to the
installation of the conflicted package.
Also, return false from dir_belongsto_pkgs on errors. Previously, we
simply continued which could return true even if we were unable to
actually establish that the package owned the entire tree.

When attempting to install a package (either via -S or -U) and the
signature is missing, the current error message "invalid or corrupted
package (PGP signature)" is very unclear. Instead inform the user
that the package is missing the required signature.

The previous implementation was overly complex with unnecessary checks
and nested conditionals. By reordering the tests and changing them to
all be checks for positive hash matches rather than non-matches, we can
collapse several cases and make the process much more linear. This
removes the need to set hash_orig = "" just to reach some of the checks
and corrects a faulty assumption that files are equivalent when the
hashing process fails.

Since 882bff36 literals would be searched before replacers, resulting in a
package being replaced by another not actually being replaced under certain
conditions (e.g. they're both in the same repo).
This change effectively reversed the expectations in test sync132. This patch
switches the order back to replacers first, thus making sure if a package is
replacing another one, the change will always happen, even if both are in the
same repo.
Note that a package replacing another one in a repo with higher priority will
not be done, see FS#11737 and test sync1105

Although technically correct, this results in my system taking ~30 seconds
to resolve all filelists when removing a package that has a directory not
owned by any package. The check for if any package own the empty directory
is a rare enough occurance, and it will be even rarer when that directory
has a directory symlink in its path, so just revert this at this stage.
