d/changelog: revert closing pygrub bugs

It appears that the pygrub script itself is still broken because of
import problems with a renamed library. Make sure we're not claiming
that the bugs are solved.

d/rules: Don't exclude the actual pygrub script

We still want to have `/usr/lib/xen-4.11/bin/pygrub`.

Thanks PryMar56 for quickly pointing out the fix on IRC.

grub.d/xen.cfg: fix default entry when using l10n

When a user uses a locale that results in translating menu item titles
into another language than English, the hardcoded "Debian GNU/Linux,
with Xen hypervisor" would not match anything.

So, use gettext to make it match the right translated entry.
Also see
- https://bugs.launchpad.net/ubuntu/+source/xen/+bug/1321144
- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=865086

Note that (thanks Ian for the info):
* When GRUB_TERMINAL is not empty and set to anything other than
  `gfxterm', grub will not do translation at all, because grub-mkconfig
  thinks that other GRUB_TERMINAL values including `serial' preclude
  non-ASCII characters, and that causes it to set LANG=C. (I have
  GRUB_TERMINAL="serial console", which caused much confusion when
  trying to test all of this).
* Just trying the printf "$(gettext... below is not enough to test if a
  translation shows up. It needs -d grub additionally for gettext, or
  TEXTDOMAIN=grub in the environment, which is probably present when
  this file gets run by update-grub.

shim: Provide separate install-shim target

When building on a 32-bit userland, the user wants to build 32-bit
tools and a 64-bit hypervisor.  This involves setting XEN_TARGET_ARCH
to different values for the tools build and the hypervisor build.

So the user must invoke the tools build and the hypervisor build
separately.

However, although the shim is done by the tools/firmware Makefile, its
bitness needs to be the same as the hypervisor, not the same as the
tools.  When run with XEN_TARGET_ARCH=x86_32, it it skipped, which is
wrong.

So the user must invoke the shim build separately.  This can be done
with
   make -C tools/firmware/xen-dir XEN_TARGET_ARCH=x86_64

However, tools/firmware/xen-dir has no `install' target.  The
installation of all `firmware' is done in tools/firmware/Makefile.  It
might be possible to fix this, but it is not trivial.  For example,
the definitions of INST_DIR and DEBG_DIR would need to be copied, as
would an appropriate $(INSTALL_DIR) call.

For now, provide an `install-shim' target in tools/firmware/Makefile.

This has to be called from `install' of course.  We can't make it
a dependency of `install' because it might be run before `all' has
completed.  We could make it depend on a `shim' target but such
a target is nearly impossible to write because everything is done by
the inflexible subdir-$@ machinery.

The overally result of this patch is that existing make invocations
work as before.  But additionally, the user can say
  make -C tools/firmware install-shim XEN_TARGET_ARCH=x86_64
to install the shim.  The user must have built it already.
Unlike the build rune, this install-rune is properly conditional
so it is OK to call on ARM.

What a mess.

tools/tests/x86_emulator: Pass -no-pie -fno-pic to gcc on x86_32

The current build fails with GCC6 on Debian sid i386 (unstable):

 /tmp/ccqjaueF.s: Assembler messages:
 /tmp/ccqjaueF.s:3713: Error: missing or invalid displacement expression `vmovd_to_reg_len@GOT'

This is due to the combination of GCC6, and Debian's decision to
enable some hardening flags by default (to try to make runtime
addresses less predictable):
  https://wiki.debian.org/Hardening/PIEByDefaultTransition

This is of no benefit for the x86 instruction emulator test, which is
a rebuild of the emulator code for testing purposes only.  So pass
options to disable this.

These options will be no-ops if they are the same as the compiler
default.

On amd64, the -fno-pic breaks the build in a different way.  So do
this only on i386.

debian/: Completely rework the packaging

Abolish the old template system.  Instead, the Xen version is left to
be updated by hand in debian/control and debian/changelog.  Elsewhere
things are templated at package build time.

Everything that is not just `dh $@' now has a comment explaining it.

Do not build the instruction emulator

Signed-off-by: Ian Jackson <ian.jackson@citrix.com>

tools/tests/x86_emulator: Pass -no-pie -fno-pic to gcc on x86_32

The current build fails with GCC6 on Debian sid i386 (unstable):

 /tmp/ccqjaueF.s: Assembler messages:
 /tmp/ccqjaueF.s:3713: Error: missing or invalid displacement expression `vmovd_to_reg_len@GOT'

This is due to the combination of GCC6, and Debian's decision to
enable some hardening flags by default (to try to make runtime
addresses less predictable):
  https://wiki.debian.org/Hardening/PIEByDefaultTransition

This is of no benefit for the x86 instruction emulator test, which is
a rebuild of the emulator code for testing purposes only.  So pass
options to disable this.

These options will be no-ops if they are the same as the compiler
default.

On amd64, the -fno-pic breaks the build in a different way.  So do
this only on i386.
