Lots of fixes for screwy code formatting, plus:

make streams public by default, send ice-private: 1 to make them private.
However, default config file has yp servers commented out.

A little fix for compilation on some solaris systems

Redo some config file stuff: now all the passwords are inside an element
<authentication>, (though for now they're also accepted in the old location),
and added admin username and password. Move some of the admin activities over
to using the admin passwords (admin action that affect a mountpoint use the
source password)

Fill in some (but not yet all, maybe i'll do that later) of the infrastructure
for per-mountpoint passwords.

Fix lots of headers/code so that it works properly/portably  on non-win32
systems.
