Boot charting support.

Select (B)ootchart in advanced options in configure, and logf will record timings for various stages of boot, for performance comparisons. Format logged is:
BC:>function_name,123,80
where 123 is the line number, 80 is the number of ticks since boot. This can be loaded as CSV into a spreadsheet.
