b4d3699047 Introduce reset mechanics to microcontroller. 
This allows one to configure how a subsequent reset will behave and
also trigger a reset.

Fixes #350 and fixes #173

1276ce59c3 Fix display orientation for _stage module 
Initially this library assumed the display is rotated by 90 degrees, so
the x and y were swapped. I'm now handling the display rotation in the
driver, with the hardware display settings, so the library should use
a sane order of x and y. This way it will work with any display
orientation.

216fcedfbb Add a _stage module (#398) 
This is a C module with some low-level functions required for the
CircuitPython "stage" library. It provides support for fast
rendering of tile grids and sprites on SPI-based RGB displays.

78f6c2232c Allow empty reads and writes for busio.SPI 
This is mostly for convenience, so that user code doesn't
need to add additional checks.

Also, bring the bitbangio into compatibility with busio wrt. empty
buffers.

c066e4da8b Add board definition for the uGame handheld console 
This is a board definition for the uGame project:
https://hackaday.io/project/27629-game

uGame is a small handheld game console programmable with
CircuitPython. The hardware part of the project is pretty
much stable by now.

9bcc1057ca Gracefully reset the gamepad module (#356) 
If a soft reset happens while the gamepad module is scanning for button
presses, there is a moment when the pins get de-initialized, but the
gamepad module is still trying to read them, which ends in a crash.
We can avoid it by disabling scanning on reset.

6c7d35c40c esp8266: Correct SPI functionality when write_value is provided. 
It used to introduce extra clocks to the bus rather than changing the
value output.

This fixes SD cards.

dbd3f15168 1. Use lib/libm for small (non-Express builds) to gain back a lot of flash space. 
2. Add flag INTERNAL_LIBM to mpconfigboard.mk files to signal using lib/libm.
3. Fix floating-point warnings in lib/libm
4. Turn off -finline-limit, no longer needed due to 1.
5. Add explicit flags for SPI_FLASH_FILESYSTEM and INTERNAL_FLASH_FILESYSTEM
to mpconfigboard.mk files, so they don't need to know the name of the .c file
that implements those. Makefile takes care of checking the flags and including
the right files.
