[PATCH 05/36] xen/xmalloc: add kmalloc() and kfree() aliases

[Denis Mukhin via B4 Relay <devnull+dmukhin.ford.com@xxxxxxxxxx>]

From: Denis Mukhin <dmukhin@xxxxxxxx>

Move existing aliases to a common header so those could be used in the new
code.

The code looks simpler w/ kmalloc(): type specification of the
object being allocated is not required, e.g.:
...
  struct my_obj_s *obj;

  obj = kmalloc(sizeof(*obj), 0);
...
