This updates the minimal supported version of CMake to 3.16, which in turn enables us to use more CMake features and have a cleaner build system.
This is the version that provides most new features and also the one we use in our latest docker image for CI.
SD card example prints the line which looks like:
Name: 00000
If only part of the line is received, the regular expression in the
test still matches, and partial name is obtained. Later the example
test expects to see the same name in the file read from the SD card.
This check fails, because only partial name was received earlier.
Fix by adding a CR to the regular expression so that the entire name
is matched.
Too short timeouts often cause useless failures on large-capacity SDs (16GB+)
Fixed by adding 60 sec timeout on new "Filesystem mounted" checkpoint
