Instead of assuming the maximum PWM value is 255, export a constant
from the firmware to the host with the maximum value.

Those that reach Klipper via github may jump directly to the docs/
directory in search of documentation. Add README.md and rework
Overview.md with that in mind.

The term "firmware" is ambiguous - it could refer to the entire
project (host and micro-controller software) or to just the
micro-controller software. Avoid the term in the documentation.

The Klipper software has progressed to the point where it does not
need to be described as "experimental" software.

Detect avr gcc v4.8.1 and then disable warnings during the klipper.o
linking to suppress bogus "misspelled signal handler" warnings.

Add a system startup script so that Klipper can automatically start at
boot time. Create an installation script that will install the system
dependencies and the startup script.

No need to recommend users disable "SD card support" in octoprint -
instead, just ignore the M21 command.

Debugging file.

Rename sched_timer_kick() to sched_timer_dispatch() and move its loop
into its callers in the board code. This eliminates the need to
export timer_try_set_next() from the board code.

Some additional tweeks to the scheduler has resulted in minor
improvements to the stepper benchmarks.

Introduce a TICKS() macro during config parsing that will translate
time in seconds to time in clock ticks.

Move the logic to calculate and report the stepper's current position
from endstop.c to stepper.c. This localizes the stepper code into
stepper.c.

Add initial support for micro-controller resets via the Arduino reset
mechanism. Also, automatically attempt a firmware restart if the
printer CRC does not match.

Allow sendf() to be called from irq and timer context - check for the
case where sendf() is called while already in sendf() and simply
discard those messages. This makes it safe to use output() debugging
calls even in irq and timer context.
