This adds a new config directory for global derived metrics definitions,
loaded by libpcp __dminit() if $PCP_DERIVED_CONFIG is NOT set in the
environment.
Adds iostat.conf derived metrics and a new Iostat view for pmchart. Since this
is
all client side, the new derived metrics and pmchart view work on current pmcd
and
existing archives. Generic tools can now report Iostat metrics, and any other
derived metrics that are added to the global config directory. e.g. if you only
have
one disk, the following is almost the same as iostat:
pmrep disk.dev.{read_bytes,write_bytes,await,avg_rqsz,avg_qlen,util}
Still to come: QA - please don't consider merging this until I've finished
the necessary QA updates and added a few new tests.

pmchart: add Iostat view using disk metrics and derived iostat metrics
This is a new multi-tabbed view showing disk and device-mapper traffic
and most of the traditional iostat metrics. Some of these metrics are
derived, see /var/lib/pcp/config/derived/iostat.conf.

libpcp: load global derived metrics config by default
If PCP_DERIVED_CONFIG is NOT defined in the environment, then __dminit()
now loads derived configs from $PCP_VAR_DIR/config/derived by default.
This follows on from previous commit 689c031ca6f5, where we now ship
an iostat.config.
A follow-up change will move the global derived config directory and
iostat.config into the pcp-conf package (currently in pcp base package).
Also, some QA changes to follow.

pmchart: fix an autoscale bug when loading a view in archive mode
Fix an issue in pmchart when loading a view in archive mode, autoscale
isn't properly performed until a pmtime event is received (was initially
fixed scale at 0 .. 1000). Also improves console diagnostics in related
areas of code. Fix is in GroupControl::adjustArchiveWorldViewForward().
