It's simple and it works. Why don't we just go with this simple approach
first, and add fancy stuff later on?

I am interested in your library, but it does much more than is needed in
BinpkgExtractorAsync.The requirements are:
1) Map bzip2, xz, or gzip to an appropriate decompression command. The
command should be guaranteed to support -c and -q options, since
BinpkgExtractorAsync relies on them.
2) Respect the user's PORTAGE_BUNZIP2_COMMAND and PORTAGE_BZIP2_COMMAND
variables.
