Reading a gzipped string value from hypfs doesn't add a 0 byte at the
end. Fix that.

Instead of each library having an own include directory move the
official headers to tools/include instead. This will drop the need to
link those headers to tools/include and there is no need any longer
to have library-specific include paths when building Xen.
While at it remove setting of the unused variable
PKG_CONFIG_CFLAGS_LOCAL in libs/*/Makefile.

For each library built two variants of pkg-config files are created
from a per-library template: an "official" one for installation on
the user's system, and one used for building internal tools, like e.g.
qemu.
Instead of the template which is looking very similar for all libraries
generate the pkg-config files directly from make variables.
This will reduce the need to specify some pkg-config file entries in
the templates, as the contents can easily be generated from available
data (e.g. "Version:" and "Requires.private:" entries).
Especially the variant used for building internal tools needs to gain
additional runtime link parameters for the internally used libraries,
as otherwise those won't be found by the users (e.g. qemu).

Library related make variables (CFLAGS_lib*, SHDEPS_lib*, LDLIBS_lib*
and SHLIB_lib*) mostly have a common pattern for their values. Generate
most of this content automatically by adding a new per-library variable
defining on which other libraries a lib is depending. Those definitions
are put into an own file in order to make it possible to include it
from various Makefiles, especially for stubdom.
This in turn makes it possible to drop the USELIB variable from each
library Makefile.
The LIBNAME variable can be dropped, too, as it can be derived from the
directory name the library is residing in.

In order to harmonize names of library related make variables switch
XEN_LIBXEN* names to XEN_libxen*, as all other related variables (e.g.
CFLAGS_libxen*, SHDEPS_libxen*, ...) already use this pattern.
Rename XEN_LIBXC to XEN_libxenctrl, XEN_XENSTORE to XEN_libxenstore,
XEN_XENLIGHT to XEN_libxenlight, XEN_XLUTIL to XEN_libxlutil, and
XEN_LIBVCHAN to XEN_libxenvchan for the same reason.
Introduce XEN_libxenguest with the same value as XEN_libxenctrl.
No functional change.

In case of an error in xenhypfs_open() the error path will cause a
segmentation fault due to a wrong sequence of closing calls.

As compilers are free to choose the width of an enum they should be
avoided in stable interfaces when declaring a variable. So the
struct xenhypfs_dirent definition should be modified to have explicitly
sized members for type and encoding and the related enums should be
defined separately.
Additionally it is better to have a larger flags member in that struct
with the "writable" indicator occupying only a single bit. This will
make future additions easier.
