Commit 459e5219 added a special case to the boundary checks to permit
homing moves. In some cases, the second home retract could also be
outside the normal boundary checks - extend the special case to also
permit that move.

The gitdir previously could be absent and produce a version of "" in
spite of checks for it. Fixed.
Parent directories with shlex-interpreted characters in their names
could be misinterpreted. Removed shlex parsing.
Packagers may want to remove the git history to slim down the package
size, so add an option for using a file 'version' in the klippy
directory to set version without using git.

Some users increase max_extrude_cross_section to avoid issues with
some slicers. However, increasing that value also increases the
defaults for the max_extrude_only parameters which is not obvious.
Base the max_extrude_only defaults only on the configured nozzle
diameter.

Setting the square corner velocity to zero would cause stuttering
during the test if a bed mesh is in effect. It's possible to get the
desired effect by reducing the square corner velocity and setting the
pressure advance lookahead time instead.

Sometime bossac reports an error during chip restart. It appears this
error is spurious - just suppress it.

Scaling the timer on the system bus has a notable impact on
performance. So, scale the timer within the timer hardware itself.

The Trinamic stepper motor drivers are capable of reporting the
stepper phase - add support for using that capability to the
enddstop_phases module.

The Python 2.x ConfigParser doesn't support stripping of trailing '#'
style comments. Do that manually before parsing the config.

Only clear the internal sync_print_time flag if the code performs a
regular "lazy" flush of the look-ahead queue. This helps build the
look-ahead queue even when running internal scripts.

Now that "Klipper state" messages are proactively sent, it is
redundant to send the "preparing to restart" message.

It appears the sam3x8e has a primitive cache prefetch mechanism (it
prefetches 32 bytes at a time aligned to a 16 byte boundary).
Aligning the main loop in timer_dispatch_many() to a 16 byte boundary
significantly improves performance.

If sched_try_shutdown() is not inlined into timer_dispatch_many() it
can have a significant impact on benchmarks. (Even though the
function isn't called in practice, the call causes gcc to organize the
function differently.)

Some older versions of gcc need the __always_inline directive in order
to inline timer_read_time. Inlining that function is important for
performance on the stm32f1.

As long as timer_read_time() is inlined, I get better performance with
gcc -O2 optimization. The binary is also dramatically smaller and O2
better matches the other platforms.
