Robert Jordens b03d9f4c14 genlib/fifo: add flush, expose level in SyncFIFO 
AsyncFIFO would need versions of flush and level in each clock domain
plus some handshaking on double flush.

Sebastien Bourdeauducq bac62a32a9 Make memory ports part of specials 
This is needed to handle cases where a single memory has ports
in two different modules, and one of these modules is subject
to clock domain remapping. The clock domain of the port in that
module only must be remapped.
