g_str_equal: Provide macro for optimization

Browse Source 
g_str_equal() is a nicer API than strcmp()==0, and less error prone.
However, forcing a function call prevents compiler from doing
optimizations. In the case it is not used as callback to GHashTable,
provide a macro that calls strcmp directly. This also has the side
effect that it forces arguments to be `const char *` instead of
`gconstpointer` in the case it is not used as callback, which adds type
safety.

Fixes: #2775
