[PATCH 1/1] shared: add nm_streq() and nm_streq0() macro

[Thomas Haller <thaller redhat com>]

Using strcmp() to test for string equality is a well known pattern.
However the inverse logic still hurts my brain every single time,
especially in more complex expressions.

nm_streq() should be preferred over strcmp(). And there is a counterpart
nm_streq0() which uses g_strcmp0().

Kernel and systemd have also streq() macros.
