Most callers would pass FALSE to nm_utils_error_is_cancelled(). That's
not very useful. Split the two functions and have nm_utils_error_is_cancelled()
and nm_utils_error_is_cancelled_is_disposing().
and _nm_utils_inet6_ntop() instead of nm_utils_inet6_ntop().
nm_utils_inet4_ntop()/nm_utils_inet6_ntop() are public API of libnm.
For one, that means they are only available in code that links with
libnm/libnm-core. But such basic helpers should be available everywhere.
Also, they accept NULL as destination buffers. We keep that behavior
for potential libnm users, but internally we never want to use the
static buffers. This patch needs to take care that there are no callers
of _nm_utils_inet[46]_ntop() that pass NULL buffers.
Also, _nm_utils_inet[46]_ntop() are inline functions and the compiler
can get rid of them.
We should consistently use the same variant of the helper. The only
downside is that the "good" name is already taken. The leading
underscore is rather ugly and inconsistent.
Also, with our internal variants we can use "static array indices in
function parameter declarations" next. Thereby the compiler helps
to ensure that the provided buffers are of the right size.
"nm-cloud-setup" can by configured via environment variables. Mark all the
names of such variables with NMCS_ENV_VARIABLE() macro. This allows to grep
for them.
