Zlib client

[Alexey M. <al...@hs...>]

hello,

I've finally beaten the Zlib-client.  It successfully checked out
stock CVS from cvs.cvshome.org using compression.  The checked out
files compile ;) 


There is one glitch left: it sometimes hangs forever at the end of the
checkout.  I'll just need to set O_NONBLOCK and fix that (tomorrow).



Thing to note about ncli: now any read() method could return -1, and
set errno = EAGAIN (that's the only value of errno that could possibly
appear).  I thought about adding this long ago, but with zlib-client I
was forced to.

Enjoy,
