In tests nm-logging will directly write using g_log. Also, non-core components
use g_log() for logging. glib will not print messages with level
G_LOG_LEVEL_INFO or G_LOG_LEVEL_DEBUG unless G_MESSAGES_DEBUG is set.
When the user specifies NMTST_DEBUG turning on 'debug' or
'log-level=DEBUG' it can be reasonably assumed that he wants to see
debug messages. nmtst_init() now sets G_MESSAGES_DEBUG=all.
The user can disable this behaviour, by setting instead G_MESSAGES_DEBUG='',
because nmtst_init() will not reset an existing G_MESSAGES_DEBUG.

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.
