shared: add nm_streq() and nm_streq0() macro

Browse source 
Using strcmp() to test for string equality is a well known pattern.
However the inverse logic still is still hard to grasp especially in
more complex expressions.

nm_streq() should is an alternative to use strcmp(). And there is a counterpart
nm_streq0() which is based on g_strcmp0().

Kernel and systemd have also similar streq() macros.
