Fix the following:

 WARNING: Target "nm-utils/tests/test-shared-general" has a path
 separator in its name.  This is not supported, it can cause
 unexpected failures and will become a hard error in the future.

No options are implemented yet.

  git ls-files -z -- ':(exclude)src/settings/plugins/keyfile/tests/keyfiles' | xargs -0 -n1 sed -i '1 { /^$/d }'

We no longer add these. If you use Emacs, configure it yourself.

Also, due to our "smart-tab" usage the editor anyway does a subpar
job handling our tabs. However, on the upside every user can choose
whatever tab-width he/she prefers. If "smart-tabs" are used properly
(like we do), every tab-width will work.

No manual changes, just ran commands:

    F=($(git grep -l -e '-\*-'))
    sed '1 { /\/\* *-\*-  *[mM]ode.*\*\/$/d }'     -i "${F[@]}"
    sed '1,4 { /^\(#\|--\|dnl\) *-\*- [mM]ode/d }' -i "${F[@]}"

Check remaining lines with:

    git grep -e '-\*-'

The ultimate purpose of this is to cleanup our files and eventually use
SPDX license identifiers. For that, first get rid of the boilerplate lines.

nmtst_get_rand_int() was originally named that way, because it
calls g_rand_int(). But I think if a function returns an uint32, it
should also be named that way.

Rename.
