Inspect POST buffer in mg_get_var() only if first call of get_var() returns -1

Browse Source 
In mg_get_var() the first call of get_var() inspects the variables of
the query string. If the requested variable is found but the destination
buffer is too small to hold the variable, return -2 right away. If it's
not found, make the second call of get_var() to inspect the POST buffer.
