pkgin testing

[Jonathan Perkin <jperkin%mnx.io@localhost>]

Hi!

I've been making a huge number of changes to pkgin recently, and it'd be 
great if anyone interested could test it out prior to me cutting the 
next release.  I've been adding a lot of new code to the test suite, but 
it's always good to get some more real-world testing, as despite a huge 
amount of testing I'm always very wary of causing new regressions.

Highlights:

 * SUPERSEDES support.

 * Completely written depends/impact path, fixing many install and 
   upgrade scenarios.

 * Significant performance improvements.  As an example "pkgin -n 
   upgrade" is approximately 50x faster, and uses 4x less RAM, 
   when running on a system with around 1,500 packages installed.

 * Fixed package ordering.

 * Fixed handling for alternative matches.

 * Many cleanups and code refactoring.

To get it, build with GITHUB_TAG updated in pkgtools/pkgin/Makefile to 
the latest from https://github.com/NetBSDfr/pkgin (currently 
81a095a448cfbfd002e4afd42f04ee3eb166a5cd), then copy the resulting 
binary somewhere.

Note that if you want to go back to an older version afterwards, you'll 
need to run "pkgin -f update" first as database changes mean older 
versions will crash as they are unable to handle the new format.

Please raise any issues with the new version at:

  https://github.com/NetBSDfr/pkgin/issues

Thanks!
