Log message:
pbulk-base-0.56: Support for adjusting scheduling

Switch to a weighted scheduling algorithm. Before, build order was based
on number of reachable nodes in the dependency graph. This assumes that
heavy packages are required by other packages. Some big packages
nowadays violate that assumption and can result in long periods at the
end of a build where only a few builders are active. Annotating those
packages with PBULK_WEIGHT in the pbulk-index output can boost their
priority to let them be built earlier. The default weight is 100.

Note: the pbulk-build report has grown an extra field per line with the
computed effective weight of each package. This file is normally used
only internally.

Log message:
pbulk-base-0.55: Optimize DAG computation

Before the build starts, pbulk-build computes the size of the dependee
graph for each package. This is naturally a O(n^2) problem. The existing
algorithm used a linked list to check for duplicates. Replace this with
a simple array for seen markers. While it is still quadratic to reset
the array for every package, clearing the array is a simple memset.
A no-op run after a full build now needs 0.3s on my work station
compared to over 3min before.

pbulk: make rsync dependency a default-on option

Log message:
pbulk: Avoid cleaning $prefix on every bulk build in master mode.

Whatever is in $prefix shouldn't affect the result -- both scanning
and building happen in the workers -- and it is a bit of a nasty
surprise for merely issuing bulkbuild-restart to nuke all the host's
installed packages.
