The DEBUG() function requires a minimal stack size for printf().
This is not always availiable.
To still allow static debug messages, introduce DEBUG_PUTS() that
gets resolved to puts() and does not carry such stack size requirements.
Currently the bitfield type mixes up the order of bits: While the byte
order is big-endian (most significant byte first), the bit order of each
single byte within the bitfield is little-endian (most significant bit
last). While this isn't a problem for most applications of the bitfield
type it becomes one when sending the bitfield over the network (as done
e.g. in the [ACKs of Selective Fragment Recovery][SFR-ACKs]).
This change unifies byte order and bit order to both be most
significant bX first.

ESP32 log output was always tagged with additional information by default. The tag consists the type of the log message, the system time in ms, and the module or function in which the log message is generated. By introducing module `esp_log_tagged`, these additional information are disabled by default and can be enabled by using module `esp_log_tagged`.
Log module of ESP32 supports colored log outputs when module `esp_log_color` is enabled. The generation of colored log outputs is realized by a extending the bunch of macros with an additional letter indicating the type of log message,
For the implementation of the colored log output, two versions of the bootloader are introduced, one version with colored log output and one version without colors.
The idea is not fill the memory on the computer running a native instance and to be able to test on hardware. The test application is reworked similarly as the memarray test application. Macro are now overridable and printed at the beginnined of the test: this allows easier automatic testing
`led_init()` is already protected by an `#ifdef`, so no need for
the weak symbol.
The problem is that the weak function does not get overridden, even when
the board provides it's own led_init(), resulting in no LEDs being
initialized.
miniterm.py is a simple terminal program that is included with pyserial.
This means that it is available wherever pyterm can work. It allows raw
access, does line translation and passes through special characters.

Added driver for the WS2812/SK6812 RGB LEDs often sold as NeoPixels, which due
to their integrated RGB controller can be chained to arbitrary length and
controlled with a single GPIO.
For regular modules, adding files to BLOBS is sufficient to create the
corresponding headers.
Application modules are different, as they use a minimal makefile
(makefiles.application.inc.mk) to build, thus application level
variables are not available.
This commit makes Makefile.include pass BLOBS to the application
Makefile as APPLICATION_BLOBS, and application.inc.mk use that variable
as value for BLOBS.
The indirection is necessary so submakefiles (e.g., those visited by
DIRS) do not hard override BLOBS.
The setter function approach makes this switchable at runtime (antenna
diversity?).
Documentation is added both to the board introduction page and the
individual pins and functions.
The particle-{argon,boron,xenon} all have a uFL connector and a PCB
antenna for 2.4GHz radio, connected by a SKY13351-378LF switch
configured by a VCTL[12] pin pair.
This sets the default configuration to use the PCB antenna, as driving
an unconnected antenna will deteriorate radio performance.
