This adds support for CIRCUITPY_WIFI_SSID and CIRCUITPY_WIFI_PASSWORD
in `/.env`. When both are defined, CircuitPython will attempt to
connect to the network even when user code isn't running. If the
user code attempts to a network with the same SSID, it will return
immediately. Connecting to another SSID will disconnect from the
auto-connected network. If the user code initiates the connection,
then it will be shutdown after user code exits. (Should match <8
behavior.)
This PR also reworks the default displayio terminal. It now supports
a title bar TileGrid in addition to the (newly renamed) scroll area.
The default title bar is the top row of the display and is positioned
to the right of the Blinka logo when it is enabled. The scroll area
is now below the Blinka logo.
The Wi-Fi auto-connect code now uses the title bar to show its
state including the IP address when connected. It does this through
the "standard" OSC control sequence `ESC ] 0 ; <s> ESC \` where <s>
is the title bar string. This is commonly supported by terminals
so it should work over USB and UART as well.
Related to #6174
Use this function instead of several individual configuration functions
to configure such things as Baud rate, transfer size, stop bits,
parity...
This function also resets both the RX and TX Hardware Fifo
reset functions are called to setup the hardware.
This allows the compile stage to optimize most of the translate()
function away and saves a ton of space (~40k on ESP). *However*, it
requires us to wait for the qstr output before we compile the rest
of our .o files. (Only qstr.o used to wait.)
This isn't as good as the current setup with LTO though. Trinket M0
loses <1k with this setup.
So, we should probably conditionalize this along with LTO.
