Generate many make variables automatically instead of having to
reiterate common patterns multiple times.

This is part I of a larger series. The previous version included the
move of multiple other libraries below tools/libs. In V2 I have
decided to split the series up, as this makes it easier to commit
some parts early.

Part I just contains some cleanup work and the automatic generation
of the make variables, without moving any other libraries under
tools/libs.

Patches 1-5 can go in independently from each other, just patch 6
depends on some of the first 5 patches.

The other parts will be sent out later, moving more libraries.

Changes in V2:
- split series up in multiple parts, part I containing only patches
  1-5 and 12 of the series V1
- eliminate the LIBNAME variable from tools/libs/*/Makefile (patch 6)

Juergen Gross (6):
  stubdom: add stubdom/mini-os.mk for Xen paths used by Mini-OS
  tools: switch XEN_LIBXEN* make variables to lower case (XEN_libxen*)
  tools: add a copy of library headers in tools/include
  tools: don't call make recursively from libs.mk
  tools: define ROUNDUP() in tools/include/xen-tools/libs.h
  tools: generate most contents of library make variables
