Rather than accumulating generally useful rST substitution definitions in individual rST files, create a defs.rst.inc where we can define these. To start with it has the |qemu_system| definition from qemu-block-drivers.rst. Add a comment noting a pitfall where putting literal markup in the definition of |qemu_system| makes it misrender manpage output; this means the point-of-use must handle the literal markup (which is almost always done by having it inside a parsed-literal block).

   Generally useful rST substitution definitions. This is included for
 | 
						|
   all rST files as part of the epilogue by docs/conf.py.  conf.py
 | 
						|
   also defines some dynamically generated substitutions like CONFDIR.
 | 
						|
 | 
						|
   Note that |qemu_system| is intended to be used inside a parsed-literal
 | 
						|
   block: the definition must not include extra literal formatting with
 | 
						|
   ``..``: this works in the HTML output but the manpages will end up
 | 
						|
   misrendered with following normal text incorrectly in boldface.
