bus updates on a particular command queue.

The sam3 i2c code and the linux code use a 7-bit i2c address, while
the avr, lpc176x, and samd21 i2c code uses an 8-bit address with the
least significant bit always zero. A similar issue occurred in the
host code (sx1509.py and replicape.py use 7-bit addresses while
uc1701.py and mcp4451.py use 8-bit addresses).
Consistently use 7-bit addresses in all the code. This breaks
compatibility between host and mcu software, so make a change to the
config_i2c command to force users to synchronize software updates.
This also breaks common Smoothieboard configs, so update the mcp4451
code to validate the i2c_address.

Add a self.all_framebuffers variable and change self.vram to only
contain the new display data. This allows the main code to access the
self.vram member variable without the need to index for current/old
data. (It also updates the code to match the latest st7920 and
hd44780 code.)

Add write_glyph() support to hd44780.py. Update uc1701.py and
st7920.py to support writing single character glyphs via
write_glyph().

Move the st7920 icon rendering optimizations from display.py to
st7920.py. This simplifies the code for other displays.

Change the name of the config registration method and pass an explicit
reference to the callback to the new method. This makes the
relationship between mcu registration and build_config() more clear in
the calling code.

Don't pass pin_type to lookup_pin() - instead, if a pin can be
inverted or can have a pullup, then the caller must explicitly specify
that when calling lookup_pin(). This simplifies the code for the
cases where it is not valid to invert or pullup.
Explicitly pass the pin_type to setup_pin() and have ppins.setup_pin()
apply default pullup and invert flags.
