Changes in v2 from the cover letter
- SystemStats instance survives between event handler calls by storing it in the corresponding datastore, instead of using a global variable, and open files get closed properly when the build ends. This should work better with memres bitbake (not tested, though, because of YOCTO #10741).
- Sampling now already starts when setscene tasks start to run.

Cover letter [PATCH V2 00/11] system statistics sampling
buildstats.bbclass gets extended so that disk bandwidth and capacity, CPU and memory usage get sampled at regular time intervals by default. pybootchart had code for most of that data, which gets restored and re-enabled. The disk capacity graph is new.
The original pybootchart just stored raw dumps of the special files under /proc. bitbake builds run longer, so a more compact ("reduced") format is used.
Logging disk capacity was mostly motivated by some work on enhancing rm_work.bbclass behavior, but could also be useful for others ("how much free space did my build need").
Changes in V2:
- SystemStats instance survives between event handler calls by storing it in the corresponding datastore, instead of using a global variable, and open files get closed properly when the build ends. This should work better with memres bitbake (not tested, though, because of YOCTO #10741).
- Sampling now already starts when setscene tasks start to run.
