#2 Limited number of event slots

[Dave Fowler]

Only 64 event slots are available for AsyncFree
components. If one is using a
TAfComPort/TAfDataDispatcher pair for each active
serial port this limits applications to a total of only
32 active ports.

I suggest AfSafeSync.pas is modified to increase
AfMaxSyncSlots. Also, an exception should be raised if
the application is unable to obtain a free event slot.
