pbuilder build-dependency resolution speedup

[Michael Vogt]

Dear Friends,

people (well, dholbach) have been complaining about pbuilder being
slow when it resolves build dependencies. 

I looked into this a couple of days ago and it turned out that the
used script is not optimal. I wrote a new one that uses gdebi and that
should speedup the calculation significantly (one pass instead of one
pass per b-d and b-c). Its not default yet as it got little testing so
far, but if you feel that your pbuilder is too slow, just change:

PBUILDERSATISFYDEPENDSCMD="/usr/lib/pbuilder/pbuilder-satisfydepends"
to
PBUILDERSATISFYDEPENDSCMD="/usr/lib/pbuilder/pbuilder-satisfydepends-gdebi"

Feedback is welcome of course :)

Cheers,
 Michael
