Make RPC call dispatch threaded
* src/libvirt_private.syms, src/util.h, src/util.c: Add
a general virSetNonBlock() helper with portability to
Win32
* src/remote_internal.c: Re-factor I/O to allow RPC calls
from multiple threads to be handled concurrently.

* src/domain_conf.h src/lxc_driver.c src/uml_driver.c: virDomainObj * src/domain_conf.h src/lxc_driver.c src/uml_driver.c: virDomainObj
