docs: generate documentation for Kconfig options
This adds a simple script which parses Kconfig files using Kconfiglib
and emits ReST document with the list of all options. For each option
a link target is generated, to make it possible to link to any Kconfig
option from the rest of the documentation.
Since Kconfiglib is not on PyPI, the latest version (45f87b9d) is
bundled into the docs directory.

idf_monitor: send CR when ENTER is pressed

ENTER is pressed on the keyboard. Make behavior of idf_monitor

idf_monitor: use cancellation and Console.getkey from pyserial 3.3.0+
Between 3.1.0 and 3.3.0, pyserial had thread cancellation implemented
using a select, which blocked on the stdin and an auxiliary pipe. When
thread had to be cancelled, a byte would be sent into the pipe,
unblocking stdin.
Unfortunately, this method suffers from a problem with using select on
a StreamReader (which represents the decoder wrapped around stdin).
In some cases, when the TTY sends an escape sequence in response to
an escape sequence received from serial, this escape sequence will not
be read from stdin until some key is pressed.
In https://github.com/pyserial/pyserial/commit/cab3dab, this method
was replaced with an TIOCSTI ioctl. This change makes sure we use the
new cancellation method even if the script is running with older
pyserial.

vfs: support for blocking reads, more newline conversion options
Previously VFS driver for UART could only use simple non-blocking
functions to read from and write to the UART. UART driver provides more
complex blocking and interrupt-driven functions, which can be used
instead.
This commit adds optional support for using UART driver's functions.
Also added is a more flexible mechanism for configuring newline
conversion rules on input and output.
This commit also fixes a bug that all UARTs shared one static variable
used as a character buffer in newline conversion code. This variable is
changed to be per-UART.

mbedtls: Expose compile-time config, disable some things by default

* Defaults no longer get "Bad" howsmyssl.com rating (no more vulnerable 3DES)

sdmmc: add support for high speed (HS) mode
By default SD cards are initialized in default speed (DS) mode. Enabling

the switch.
This change implements SWITCH_FUNC command and adds the procedure to
switch to HS mode.

indicates whether the next command is going to be an APP command.

SWITCH_FUNC command, which has opcode 6, same as APP_SET_BUS_WIDTH.

fix(spi_master): make the address field more intuitive to use.
The address field should be placed at the highest bits of address and slv_wr_status registers. Instead of breaking the address into two parts and fill in each register, move the address to the highest bits and write to the registers respectively.
Breaking change: if you fill-in the SPI address filed in a previous version in some way and it works correctly, you still have to rewrite the address, in a more intuitive way.
