In this mode, nmtst itself will not log anything and not set the logging
level. Also, it will set g_log_set_always_fatal().
This is for tests that want to assert against all logged messages via
g_test_expect_message().
In this mode also setting the logging level via NMTST_DEBUG variable has
no effect. The test is expected to manage the logging level itself and
changing the logging level might interfere with the test.
As a showcase, move keyfile/tests/test-keyfile.c to nmtst.

Interpret environment variable NMTST_DEBUG which allows
to specify 'sudo-cmd=CMD'. If the test program calls
nmtst_reexec_sudo(), it will `exec CMD "$0" "$@"`.

'inline' is needed to avoid compiler warnings about unused
functions.
Marking them only as 'inline' was simply wrong and leads to
linker errors when including the header in different translation
units.
By making them "inline static" we also don't need to foward declare the
function prototype to avoid another compiler warning.
