XBPS 0.41 is out

A new XBPS stable version has been released: 0.41. This is a bugfix release that contains a new feature reverts.

Release notes:

libxbps: another bugfix while checking required shlibs in reverse dependencies. Written another test case to verify its correctness.
libxbps: rather than checking if user has write permission on package files for removal, check if the files are owned by the same user ID. This fixes a new issue where files with only the read bit set cannot be removed. Added a new test case to verify its correctness.
xbps-create(8): xz compressed packages now use default compression level (-6) rather than max level (-9); max compression level uses too much memory and it’s much slower; by Christian Neukirchen.
Improvements for xbps bash completions, by Eivind Uggedal.
A performance improvement for xbps_file_hash(), by Enno Boland.
Added reverts field to package definitions. If defined, a package will replace all versions specified in this field even if the installed version is newer. This is helpful when a broken package is released. The maintainer can downgrade this package and define a reverts field to the broken version. On the next update xbps-install will automatically replace the broken release by the new downgraded release.
Replace xbps-packages directory by void-packages in xbps-checkvers(8), xbps-uchroot(8) and others, by Enno Boland.
