This allows using and compiling the URL handling functions of sock_util
without a network stack used.

Use pseudomodules to add a dependency on the relevant feature:
periph_spi if the abp2_spi pseudomodule is selected,
or periph_i2c if the abp2_i2c pseudomodule is selected.
Honeywell ABP2 pressure sensors series.
Implement all sensors features, only supporting the SPI version
of the sensor.
Prepare future support for the I2C interface by emphasizing where
to implement the code that will support the I2C bus version.
This changes the documentation of how to configure stdio, especially
with regard on how to configure the stdio frontends with
`printf_float`, `printf_long_long`, and `stdin`.

When executing `make generate-Makefile.ci` in the base directory,
the make system would try to call `riotgen` with `Makefile.ci`,
which does not work. Likewise with any other target like
`make generate-bogus`. The pattern rule for the prerequisites was
not evaluated by make, therefore the check did not work as
intended.
Previously, uart_poweroff() and uart_poweron() were no-ops. This
replaces them with the logic to indeed power on and power off the UART
device.

This adds the new `printf_long_long` module that can be used to enable
printing of `long long` and `unsigned long long`.
This has been implemented for `mpaland-printf`. In addition, this module
is a default module for 32-bit and 64-bit systems if `mpaland-printf` is
used, 64 bit support is not too expensive for them. (And on 64-bit
systems support for long long is needed for support of `%p`, which is
pretty basic.)
This is mainly useful for MSP430, where otherwise `mpaland-printf` would
require more memory than newlib's implementation.
This adapts to an API change for providing stdin/stdout/stderr: The
macro to test whether globals are to be used is now prefixed with two
underscores.

This adds `-Wno-unterminated-string-initialization` to the `CFLAGS` if
(and only if) the compiler supports this.
This also adds `-Wno-maybe-uninitialized`. This warning has been
supported for quite some time, but the diagnostics triggers more often
with newer GCC releases.
