[Qemu-devel] [PATCH] ui: avoid use of deprecated gnutls_*_set_priority functions

[Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>]

From: Raghavendra D Prabhu <raghu.prabhu13@gmail.com>

The gnutls_*_set_priority family of functions has been marked deprecated
in 2.12.x. These functions have been superceded by
gnutls_priority_set_direct().

Re-sending as a top-level patch because the other patches in the series have
other issues/discussions.  Let's get this independent patch in.
