Implement gnttab interface on NetBSD.
The kernel interface is different from FreeBSD so we can't use the FreeBSD
version

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.

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.

Xen 4.11 shipped with a SONAME of 1.1.
For staging (and 4.12 eventually), the SONAME was bumped to 1.2 by c/s
28ca696a3. Further changes before 4.12 ships should not bump the SONAME.

and vise versa. This is only implemented for Linux as other OSes

For libxengnttab.map, introducing a new VERS* section must be matched with a
equivalent SONAME bump.
For libxencall.map, the hunk as presented would have been ok, if Xen 4.11
hadn't been released between xencall_buffers_never_fault() and xencall_fd()
being introduced. Given the timing of the release, xencall_fd() needs moving
into a new VERS_1.2 section.

DEPS_RM is currently the same as DEPS, so no functional change.
This patch is the result of two perl runes:
git-grep -l 'rm.*DEPS' | xargs perl -i~ -pe 'next unless m/^\t+rm\b/; s/\bDEPS\b/DEPS_RM/;'
git-grep -l 'RM.*DEPS' | xargs perl -i~ -pe 'next unless m/^\t+\$\(RM\)/; s/\bDEPS\b/DEPS_RM/;'
And editing tools/xenstat/libxenstat/Makefile by hand.
I verified that I didn't miss anything with this rune:
git-grep '\bDEPS\b' | grep -v include |less

Running "make uninstall" does not remove all installed files, a
situation which might cause link related issues if xen is re-installed
in a different location.
In order to make uninstall correctly remove the files it is best
the process should be done recursively by mirroring each "install"
target with an "uninstall" who removes the installed files.
An exception to this rule is uninstalling the files produced by
"qemu-xen-dir-remote" and "qemu-xen-traditional-dir", which are external
to the project. These projects do not implement an "uninstall" target so
the files have to be removed manually.

[ wei: modify this patch to use BUILD_BUG_ON in xen-tools/libs.h ]

libxengnttab will provide a stable API and ABI for accessing the
grant table devices.
The functions are moved into the xengnt{tab,shr} namespace to make a
clean break from libxc and avoid ambiguity regarding which interfaces
are stable.
All in-tree users are updated to use the new names.
Upon request (via #define XC_WANT_COMPAT_GNTTAB_API) libxenctrl will
provide a compat API for the old names. This is used by qemu-xen for
the time being. qemu-xen-traditional is updated in lockstep.
This leaves a few grant table related functions which go via privcmd
(GNTTABOP) rather than ioctls on the /dev/xen/gnt* devices in
libxenctrl. Specifically:
- xc_gnttab_get_version
- xc_gnttab_map_table_v1
- xc_gnttab_map_table_v2
- xc_gnttab_op
These functions do not appear to be needed by qemu-dm, qemu-pv
(provision of device model to HVM guests and PV backends respectively)
or by libvchan suggesting they are not needed by non-toolstack uses of
event channels.
The new library uses a version script to ensure that only expected
symbols are exported and to version them such that ABI guarantees can
be kept in the future.
After this change libxenvchan no longer needs to link against
libxenctrl. It still needs xenctrl.h in one file for xen_mb and
friends.
