libglusterfs/syncop: Add xdata to all syncop calls

This patch adds support for xdata in both the
request and response path of syncops.

Few calls like lookup already had the support;
have renamed variables in few places to maintain
uniformity.

xdata passed downwards is known as xdata_in
and xdata passed upwards is known as xdata_out.

There is an old patch by Jeff Darcy at
http://review.gluster.org/#/c/8769/3 which does the
same for some selected calls. It also brings in
xdata support at gfapi level.

xdata support at gfapi level would be introduced
in subsequent patches.
