Juergen Gross bc44e2fb31 tools: add a copy of library headers in tools/include
The headers.chk target in tools/Rules.mk tries to compile all headers
stand alone for testing them not to include any internal header.

Unfortunately the headers tested against are not complete, as any
header for a Xen library is not included in the include path of the
test compile run, resulting in a failure in case any of the tested
headers in including an official Xen library header.

Fix that by copying the official headers located in
tools/libs/*/include to tools/include.

In order to support libraries with header name other than xen<lib>.h
or with multiple headers add a LIBHEADER make variable a lib specific
Makefile can set in that case.

Move the headers.chk target from Rules.mk to libs.mk as it is used
for libraries in tools/libs only.

Add NO_HEADERS_CHK variable to skip checking headers as this will be
needed e.g. for libxenctrl.
