Log message (7 lines):
Rework bufchain code to allow for variable-sized granules.  
bufchain_add() now allocates at most one new granule.  Granules still 
have a minimum size, so small adds still get coalesced.

The main practical consequence of this is that PSCP and PSFTP now 
generate 4K SSH packets rather than 512-byte ones.  Also, the compiled 
code (on my Ubuntu box) is fractionally smaller.
