This is a refactor and refresh of the code used to find where we should
download packages.
* Incorporate suggestions from FS#25435 to use TMPDIR from the
environment if set, otherwise fall back to /tmp as before.
* Make the writability tests a bit more in depth. We now do a three part
check consisting of:
- S_ISDIR(): is this even a directory
- access(W_OK): is this directory writable by the current user.
Unfortunately for root, this almost always returns that it is, but
in the case of a RO mount or NFS share inaccessible to root, this
check will exclude the directory.
- mode & (any write bit): is there a writable bit set on this
directory. This makes it possible to enforce a read-only cache
directory by setting permissions to 0555, for example.

This changes the signature of _alpm_pkg_dup() to return an integer error
code and provide the new package in a passed pointer argument. All
callers are now more robust with checking the return value of this
function to ensure a fatal error did not occur.
We allow load failures to proceed as otherwise we have a chicken and egg
problem- if a 'desc' local database entry is missing, the best way of
restoring said file is `pacman -Sf --dbonly packagename`. This patch
fixes a segfault that was occurring in this case.
Fixes the segfault reported in FS#25667.

* Move is_local standalone field to status enum
* Create VALID/INVALID flag pair
* Create EXISTS/MISSING flag pair
With these additional fields, we can be more intelligent with database
loading and messages to the user. We now only warn once if a sync
database does not exist and do not continue to try to load it once we
have marked it as missing.
The reason for the flags existing in pairs is so the unknown case can be
represented. There should never be a time when both flags in the same
group are true, but if they are both false, it represents the unknown
case. Care is taken to always manipulate both flags at the same time.

The use of warning once we had already started adding a package was
confusing as it broke the standard indent pattern. It was especially bad
if adding multiple packages as it wasn't clear what sub-messages applied
to which package being added. This should be an output change only from:

-> Computing checksums...
-> Adding package signature...
==> WARNING: An entry for 'netcfg-2.6.7-1' already existed
-> Removing existing entry 'netcfg-2.6.7-1'...
-> Creating 'desc' db entry...
-> Creating 'depends' db entry...

Previously, the behavior was such that if a sync operation required
packages from multiple repos, a download error in the first repo would
cause a hard repo, ignoring the remainder of the repositories. Change
this behavior so that we do a better job of fetching as many packages as
possible before aborting the transaction.
There's a little bit of refactoring mixed in here to get rid of some
useless variables. Since we now depend heavily on the value of
handle->pm_errno being accurate the determine the function's return
value, we clear it when the transaction state is set.
