[Libguestfs] [PATCH 0/3] protocol: Abstract out socket operations.

[Richard W.M. Jones]

I've been taking a long hard look at the protocol layer.  It has
evolved over a long time without any particular direction, and the
result is, to say the least, not very organized.

These patches take a first step at cleaning up the mess by abstracting
out socket operations from the rest of the code.  The purpose of this
is to allow us to slot in a different connection layer under the
library-side protocol (ie. one based on virStreamPtr for remote
libvirt connections).

But the refactoring is also useful both because it simplifies the code
and because it would make it easier to add multiple daemon
connections.

These changes pass all the tests with both libvirt & appliance
attach-methods, and with valgrind; *except* for tests/mount-local --
but that test was failing intermittently before this change for
reasons which I still don't quite understand.

Rich.
