0 when a protocol goes final, and non-zero for an intermediary CVS
version of a protocol that is in flux.  If we find that we're talking
to a CVS version with a different sub-protocol #, we automatically
drop back to the prior protocol that the sides have in common.

- Changed the sending of the time value in protocol 30 to support
  64-bit values without bloating positive 32-bit values.

right long-int function based on protocol version.

  {read,write}_varlong() and {read,write}_longint() functions:
  the former handles variable-length transmissions, and the
  latter is backward-compatible with older rsync versions.
- Improved the {read,write}_var{int,long}() functions to be
  simpler and to use a different byte order.
- The {read_write}_varlong() functions also allow the caller
  to specify the minimum number of bytes to send.  This allows
  time values to be sent efficiently with a 4-byte minimum,
  while length values continue to be sent with a (more optimal
  for them) 3-byte minimum.

we can copy using a spawned rsync process.

will need to try to track down how inc_recurse can deadlock.
