This piece of code implements --minimize for the commands
send and obliterate -O. The idea of this flag is to generate
patch bundles with minimal contexts. It does so by exhaustively
trying to remove patches from it, so don't expect it to run fast
on big context (I haven't tested it yet apart from small toy cases).

Since context minimizing is surprisingly fast (in the darcs.net repo
at least) let's try enabling it by default.

The following tests seem to be broken by this - haven't investigated 
the details:

apply-reorder.sh (Darcs2) (PatienceDiff)
convert.sh (Darcs1) (PatienceDiff)
issue1873-apply-failed-to-read-patch.sh (Darcs2) (PatienceDiff)
issue1909-unrecord-O-misses-tag.sh (Darcs2) (PatienceDiff)
output.sh (Darcs2) (PatienceDiff)
send-output-v1.sh (Darcs1) (PatienceDiff)
send-output-v2.sh (Darcs2) (PatienceDiff)

Fixing the tests. I guess it it easier to write tests that
work with non-minimized contexts.

On a related note, knowing that darcs now minimizes the context of
bundles, I added an explicit dependency to "minimize bundle
contexts by default".
