Juergen Gross 4664034cdc tools/libs: move official headers to common directory
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.

Juergen Gross ded08cdfa7 tools: generate most contents of library make variables
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.

Juergen Gross 725ef89164 tools: switch XEN_LIBXEN* make variables to lower case (XEN_libxen*)
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.

Andrew Cooper 28ca696a3e tools/libs: Fix stable library ABI breakage from c/s e1ed22be85
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.

Ian Jackson 300929f6e4 DEPS handling: Use DEPS_RM everywhere
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

Petre Pircalabu f2b40dabab Makefile: Fix uninstall target
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.

Ian Campbell 3e9b0d5408 tools: Refactor hypercall calling wrappers into libxencall.
libxencall will provide a stable API and ABI for calling hypercalls
(although those hypercalls themselves may not have a stable API). As
well as the hypercall buffer infrastructure needed in order to safely
provide pointer arguments to hypercalls.

libxenctrl encapsulates a instance of this interface, so users of that
library are not currently subjected to any actual changes. However all
hypercalls made internally by libxc now use the correct interface. It
is expected that most users of this library will be other libraries
providing a higher level interface, rather than applications directly.

Only the basic functionality to allocate hypercall safe memory is
moved, the type safe stuff and bounce buffers remain in libxc.

Note that the functionality to map foreign pages using privcmd is not
yet moved, meaning that an xc_interface will now contain two open
privcmd file descriptors. Foreign memory mapping is logically separate
functionality and will be moved into its own library.

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.
