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.

make[7]: *** [headers.chk] Error 1
The problem is that xentoolcore_internal.h includes _xentoolcore_list.h which
hasn't been generated yet.
The toolcore headers.chk rule (unlike the other libraries) had an additional
dependency against $(AUTOINCS), which forced the headers to be generated
first. Replicate this in the common libs.mk

The Makefile below tools/libs have a lot in common. Put those common
parts into a new libs.mk and include that from the specific Makefiles.
