Make request.Request smaller (#3351)

Browse Source 
* Make request.Request smaller

This makes the request struct smaller and removes the pointer to the do
boolean (tri-bool) as size == 0 will indicate if we have cached it.

Family can be a int8 because it only carries 3 values, Size itself is
just a uint16 under the covers.

This is a more comprehensive fix than #3292

Closes #3292
