`xbps_transaction_revdeps` will now try to add updates for packages to the
transaction if the dependency is not satisified anymore due to a package
install/update.
`xbps_transaction_prepare` will now check the return value of
`xbps_transaction_revdeps` and repeat the dependency resolution,
until `xbps_transaction_revdeps` returns 0, which means that it didn't
add any new packages to the transaction.
Added `-D, --download-only` flag to allow downloading
packages to the cache without attempting to install them.

If set it will continue with the transaction and will
just print what are the conflicting files without returning
EEXIST.
This is a temporary solution for void where there are still
some packages with conflicting files (qt5-host-tools vs qt5-tools-devel).

The previous idea was to use virtual packages in the users configuration
to satisfy dependencies by mapping them to existing installed packages.
Using virtual packages for it doesn't work as expected and trying to make
it work would break other functionalities of virtual packages, like the
version satisfaction checks for `provides` and the ability to replace
virtual packages with real packages. The virtual package functionality
should be used exclusively for virtual packages.
This allows users to specify packages packages that should be ignored.
Ignored packages in dependencies are always satisfied without installing
the package, while updating or installing a package that depends on an
ignored package.
This does NOT ignore the shlib checks, ignoring a package that provides
required shared libraries will abort the transaction as if there was no
package that provides the required shared library.
This is a trickier situation.

cc1: all warnings being treated as errors

It's basically warning about dangerous operations on strings. And as
far as I could tell, is a valid warning and not a false alarm!
This fix makes the concept of `XBPS_MAXPATH` lose a little bit of sense
as now it doesn't necessarily represent the max size of the paths used
by xbps, but instead the max allowed size of the path configured.
I think this change is ok, but I wasn't able to find any reference to
why it was chosen to be 512. POSIX mandates at least 256, so I'm not
breaking anything that wasn't broken already, and Linux seems to have
a maximum size of 4096, which is pretty safe.
Therefore, this changes should be harmless. I think.
xbps_find_virtualpkg_in_conf() needs to look at the vpkgs set up in
configuration files, not from those set by pkgdb.
As a result of this the two test cases that were failing yesterday are now
fixed.
When adding packages to the index, xbps-rindex will check if the
consistency of shlibs is broken by a package. If so, rindex will create
a stage file and commit the packages there. Once the consistency is restored,
rindex -a will commit the stage area back to the public repo and delete the
stage file.

Those are a wrapper around xbps_{array,dictionary}_internalize_from_zfile()
that prints a debugging msg when the plist file cannot be internalized.
Update xbps to use these wrappers.
We use a simple file lock that is created with O_CREAT|O_EXCL.
This should fix the concurrency issues with multiple processes
running xbps-rindex -a/-c on the same repository/arch combo.
At the time we've been searching for the pkg in a repo, no repos
were registered resulting in EINVAL. While here, if there's no
declared repos return ENOENT instead.
