This is a regression which was introduced in #16114, without resetting
the color the red color will be used for all following text written to
the terminal and will also cause the shell prompt etc. pp. to be colored
in red which is undesirable. This commit fixes this regression by using
the ANSI escape sequences to reset the color after the error message has
been written.
This makes RIOT use the integer-only printf/scanf code by default and
includes a new make parameter to select the full floating point
version. This saves about 6kB of text space when building hello-world
for the microbit board.
