Hacks to match MacOS (most recent first):
<Sys7.1> 8/3/92 Reverted <8> by bringing MoveHLow back from MemoryMgrPriv.h (to be
included indirectly by Eppc.c).

Change History (most recent first):
<8> 11/25/91 DTY Take out interface for MoveHLow() since its now in
MemoryMgrPriv.h.
<7> 11/21/91 DTY Add interface for MoveHLow here since its currently only used
by findFreeSessionRecord. Well probably want to move it into
Memory.h someday.
<5> 12/14/90 JWM moving a bit from eppc.h to eppcPrivate.h. The bit is
registerOnNetwork (0x80000000). It is not part of the API.
<4> 11/6/90 JWM removed conditional ForB2. Added a status bit to indicate
memory restart condition when trying to deliver a message in the
scanReadBQ path. This will keep the system from breaking
connections because of failure to get memory.
<2> 10/30/90 csd Make the symbols match the BBS headers.
<0> 4/26/89 JWM New Today.
