Release v4.2.0

This release contains four major additions:

1) Support for package-level bundles. A new local and upstream package
list has been introduced, which mixer parses to automatically generate
single-package bundles.

2) The bundle building algorithm has been significantly optimized. This
step now runs approximately three times faster than the previous version.

3) New TOML configuration support. Mixer now has an optional
'--new-config' flag that adds support for TOML-based configuration. A
new 'mixer config' command has been added to validate existing
builder.conf files, as well as convert legacy (INI) files into the new
TOML format.

4) Update to how mixer generates the DNF conf file used during bundle
building. This removes the dependency on m4.
