This reverts commit 07b679f70d73483930e8d3c293942416d9cd5c13.
This change appears to have broken things...
We now see applications hanging during disk accesses.
e.g.
multi-port virtio-blk device running in h/w (FPGA)
Host running a simple 'fio' test.

Instead of stacking alternative and paravirt patching, use the new
ALT_FLAG_CALL flag to switch those mixed calls to pure alternative
handling.
This eliminates the need to be careful regarding the sequence of
alternative and paravirt patching.
For call depth tracking callthunks_setup() needs to b
As a preparation for replacing paravirt patching completely by
alternative patching, move some backend functions and #defines to
alternative code and header.

This is a small series getting rid of paravirt patching by switching
completely to alternative patching for the same functionality.
The basic idea is to add the capability to switch from indirect to
direct calls via a special alternative patching option.
This removes _some_ of the paravirt macro
