xbps_remove_pkg: make sure pkgver is valid before use. 
pkgver might contain garbage due to removal of
its ancestor object (the pkg dictionary).

9e2c00ee8b libxbps: remove dangling symlinks properly. 
This fixes removal of packages that contain multiple levels
of dangling symlinks, i.e faenza-icon-theme and probably others.

2745e25740 lib/package_remove: order directories before removal 
The order of entries in files.plist is inconsistent
between different releases of xbps. Hence they must be
ordered before removal to, so sub directories are removed
before their parents.

To not propagate it later on... and also pass rv not errno to the

769a997afb Introduce xbps_plist_{array,dictionary}_from_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.

a05e039cce Revert "Stop converting relative symlinks to absolute." 
This reverts commit 9ae3638429.

This change is ok, but cannot be used right now because all existing
binpkgs were created with an old xbps-create(8).

9ae3638429 Stop converting relative symlinks to absolute. 
There's no reason to make them absolute, simply store in the metadata
the target file as is. This vastly simplifies the code and makes all
test pass correctly.

67eba7d912 Improve detection of target file in relative symlinks. 
If xbps-create(8) did not guess the target file of relative symlinks for
some reason, just compare the current symlink and what's stored as is,
without converting it to absolute.

This might happen with dangling relative symlinks or existing binary
packages that were not created with a newer xbps-create(8).

5fe3594cb5 Make sure that modified symlinks are preserved. 
When removing a package, symlinks owned by this package that have been
modified should be preserved, unless the force flag is set via xbps-remove(8).

1c20086896 Package remove: disable file owner checks if euid==0. 
All package files even not owned by root should be removed, so make sure
that those checks return success while being root.

This fixes package removal for polkit, that had /etc/polkit/rules.d
files owned by the polkitd user.

2711b07b77 Fix package files removal with only read bit set. 
The previous code was checking incorrectly if the file had the write
bit set, and this is wrong because a package could have files with
only the read bit set (0444).

0416b067d0 Use a POSIX lock for pkgdb and only issue pkgdb writes in exact points. 
- Rather than using a POSIX named semaphore use a POSIX lock (lockf(3))
for pkgdb for writers. Writers that cannot acquire the pkgdb lock will
get EAGAIN rather then being blocked.

- Due to using a file lock we cannot write the pkgdb every time a package
is being unpacked, configured or removed. Instead pkgdb is only written
at the end of a specific point in the transaction (unpack, configure, remove)
or via xbps_pkgdb_unlock().

dce26db1de libxbps: pkg remove: never remove base symlinks in the root directory. 
The /bin, /sbin, /lib, /lib32, /lib64, /var/run symlinks should never be removed
in Void, so be safe and ignore the removal of them.

Added another test to the testsuite to verify its correctness.
