scripts/buildstats-diff: implement --multi option

2016-09-30T16:14:12+00:00

Makes it possible to average over multiple buildstats. If --multi is
specified (and the given path is a directory) the script will read all
buildstats from the given directory and use averaged values calculated
from them.

All of the buildstats must be from a "similar" build, meaning that no
differences in package versions or tasks are allowed. Otherwise, the
script will exit with an error.

scripts/buildstats-diff: add read_ops and write_ops to --diff-attr

2016-09-30T16:14:11+00:00

Two new options, making it possible to compare the number of filesystem
operations of tasks. Defaults for --min-val and --min-absdiff are set to
more or less arbitrary 500 and 50 operations, respectively.

scripts/buildstats-diff: add read_bytes and write_bytes to --diff-attr

2016-09-30T16:14:11+00:00

These are I/O counter values from /proc//io and represent the
number of bytes read from / written to the storage layer. Default values
for --min-val and --min-absdiff limits are set to 512kB and 128kB,
respectively.

scripts/buildstats-diff: introduce --diff-attr

2016-09-30T16:14:11+00:00

A new command line option for choosing which "attribute" of the
buildstats to compare. At first, the already supported 'cputime' is the
only available option. But, refactoring done in this patch should make
it easy to add new attribute types.

scripts/buildstats-diff: do not hardcode field widths in output

2016-09-30T16:14:11+00:00

Dynamically adjust the width of all fields in task diff output. Makes
it easier to print other units than cputime, too.

scripts/buildstats-diff: rename --min-time and --min-timediff args

2016-09-30T16:14:11+00:00

Rename these arguments to --min-val and --min-absdiff in preparation for
supporting other "quantities" than just cputime.
