If the choice mapping uses integer keys then lookup the config option
using self.getint(). This simplifies the callers and improves the
encoding of the printer.configfile.settings export.

The previous init sequence relied on the display ignoring commands if
they are sent faster than 40us. Some displays may not have this
limit.
Rework the init to make it more robust to command transmission times.
The new init should still transition the display into 4-bit mode even
if the display processes commands faster than 40us.

Change write_graphics() from taking one pixel row of n characters to
taking all the rows and columns for one character cell.

This commit allows to modify the icons (or glyphs) in the displays that
support it. Existing icons can be modified and new icons can be added via
a [display_glyph] section in the config.

Introduce a new config based system for specifying the on-screen
contents of an lcd screen. The default screen configuration (found in
klippy/extras/display/display.cfg) is the same as the previous
hard-coded display, so this should not change behavior for existing
users.

There have been several reports that increasing the delay from 37us to
40us eliminates screen corruption on some clone hd44780 displays.
Increase the timeout value so that the standard code works on these
displays.

There is concern that some lcd boards that emulate the hd44780 don't
support text updates that wrap the two text framebuffers. Update the
code to treat the two text areas as two separate framebuffers.

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

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.
