Dan McGee 2cfcc874b9 Better error handling out of package load method
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.

Dan McGee dc3336c277 Refactor some args out of pkg_load_internal
Just pass the entire sync package in if we have it; that way we can do
any necessary operations involving it rather than have a parameter list
growing endlessly.

Dan McGee de43d00db0 Refactor signature result return format
I was trying to take a shortcut and not introduce a wrapper struct for
the signature results, so packed it all into alpm_sigresult_t in the
first iteration. However, this is painful when one wants to add new
fields or only return information regarding a single signature.

Refactor the type into a few components which are exposed to the end
user, and will allow a lot more future flexibility. This also exposes
more information regarding the key to the frontend than was previously
available.

The "private" void *data pointer is used by the library to store the
actual key object returned by gpgme; it is typed this way so the
frontend has no expectations of what is there, and so we don't have any
hard gpgme requirement in our public API.

Dan McGee c5982a3eb5 strtrim: don't move empty string
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.

Dan McGee 30d978a966 vercmp: ensure 2.0a and 2.0.a do not compare equal
We had this interesting set of facts conundrum, according to vercmp
return values:
    2.0a <  2.0
    2.0  <  2.0.a
    2.0a == 2.0.a

This introduces a code change that ensures '2.0a < 2.0.a' as would be
expected by the first two comparisons. Unfortunately this stays us a bit
further from upstream RPM code, but those are the breaks (in RPM, the
versions involving 'a' do in fact compare the same, but they are both
greater than the bare '2.0').

Dan McGee e07547ee4e Rework finding a writable cache directory
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.

Dan McGee 6d544984f2 Be more robust when copying package data
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.

Dan McGee c885a953eb Enhance and utilize database status flags
* 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.
