The mcu stats (that contain a prefix) may occur before some other
stats - make sure to only apply the stats prefix to those stats that
need it.

Use an alpha transparency on each of the stats, so that it is possible
to see how the values overlap.
Also, always enable the "awake time" stat - just use a lower alpha
transparency for it.
Also, explicitly set the graph size as some version of matplotlib have
a different default.

Update the graphstats.py graphing script so that it works with recent
stats changes - the stats can now contain groups that end with a ':'
and the print_time is no longer reset to zero on a new print.

Update the scripts used to install and "flash" the pru
micro-controller code. Also, add a "flash" script for the linux

Beaglebone board that uses a Replicape.

Now that tasks are only run when needed it's common for there to be a
larger variation in task execution time. When graphing load, consider
a 99-percentile task duration of 2.5ms to be 100% loaded (up from
1ms).

Avoid using linker magic to define the init, task, and shutdown
functions. Instead, use the compile_time_request system. This
simplifies the build and produces more efficient code.

Avoid generating unique ids via memory locations and linker scripts.
Instead, generate them using code produced by buildcommands.py.
Utilize gcc's ability to perform static string comparisons at compile
time to produce a unique id for each unique string.
This fixes a build failure on ARM introduced in 142b92b8. It also
reduces the complexity of the build.

Change the lookahead queue so that it attempts to buffer at least
buffer_time_high amount of moves when first starting a print. This
helps ensure the buffer is normally always full.
If the buffer falls below buffer_time_low then it is either due to the
end of a print or because octoprint/klippy is unable to keep up.
Change the code so that in this case the lookahead queue will attempt
to gather buffer_time_high amount of moves before restarting movement.
Update the default buffer_time_low to 1 second and buffer_time_high to
2 seconds. With the above changes a smaller buffer_time_high and a
larger buffer_time_low are more practical.
