Use just one ( ... ) for creating debian/hdrsrcfiles.

The temporary directory names, debian/hdrtmp (linux-headers package)
vs debian/headertmp (linux-libc-dev package), are confusing.
Matching the directory name to the package name is clearer, IMHO.

- We do not need tools/objtool/fixdep or tools/objtool/sync-check.sh
for building external modules. Including tools/objtool/objtool is
enough.
- gcc-common.h is a check-in file. I do not see any point to search
for it in objtree.

Select deb compression using KDEB_COMPRESS make variable. This allows to
use gzip compression for local or test builds, and that's way faster
than now-default xz compression.

Remove a bunch of files not used during external module builds:
- foreign architecture headers
- subtree Makefiles
- Kconfig files
- perl scripts
On amd64 system this looses a third of the resulting .deb size.

Debian-based distributions place libc header files in a machine
specific directory (/usr/include/<libc-machine>) instead of
/usr/include/asm to support installation of the linux-libc-dev
package from multiple architectures. Move headers installed by
"make headers_install" accordingly using Debian's tuple from
dpkg-architecture (stored in debian/arch).

It is absolutely fine to add extra sanity checks in package scripts,
but it is not necessary to do so.
This is already covered by the daily compile-testing (0day bot etc.)
because headers_check is run as a part of the normal build process
when CONFIG_HEADERS_CHECK=y.
Replace it with the newly-added "make headers".

This will be a little more efficient since unset CONFIG options are
stripped away from auto.conf, and we can hard-code the path to auto.conf
since it is never overridden.
include/config/kernel.release is generated before %pkg is run.
So, it is guaranteed auto.conf is up-to-date.

I think is_enabled() and if_enable_echo() in scripts/package/mkdebian
are useful.
builddeb also has many repetitive greps over the kernel config, so I
borrowed the idea to clean it up.

Commit 37c8a5fafa ("kbuild: consolidate Devicetree dtb build rules")
moved the location of 'dtbs_install' target which caused dtbs to not be
installed when building debian package with 'bindeb-pkg' target. Update
the builddeb script to use the same logic that determines if there's a
'dtbs_install' target which is presence of the arch dts directory. Also,
use CONFIG_OF_EARLY_FLATTREE instead of CONFIG_OF as that's a better
indication of whether we are building dtbs.
This commit will also have the side effect of installing dtbs on any
arch that has dts files. Previously, it was dependent on whether the
arch defined 'dtbs_install'.

Prior to commit 80463f1b7b ("kbuild: add --include-dir flag only
for out-of-tree build"), both srctree and objtree were added to
--include-dir redundantly, and the wrong code '$MAKE image_name'
was working by relying on that. Now, the potential issue that had
previously been hidden just showed up.
'$MAKE image_name' recurses to the generated $(objtree)/Makefile and
ends up with running in srctree, which is incorrect. It should be
invoked with '-f $srctree/Makefile' (or KBUILD_SRC=) to be executed
in objtree.

Move debian/ directory generation out of builddeb to a new script,
mkdebian. The package build commands are kept in builddeb, which
is now an internal command called from debian/rules.
With these changes in place, we can now use dpkg-buildpackage from
deb-pkg and bindeb-pkg removing need for handrolled source/changes
generation.
This patch is based on the criticism of the current state of builddeb
discussed on:

At the end of "make bindeb-pkg" I noticed the following warning:
dpkg-genchanges: warning: unknown substitution variable ${kernel:debarch}
It turns out that since dpkg version 1.19.0 dpkg-genchanges honors
substitution variables in the Description field, while earlier
versions silently left them alone, see https://bugs.debian.org/856547.
The result is an incomplete description of the linux-headers package
in the generated .changes file. Fix it by passing the kernel:debarch
substitution variable to dpkg-genchanges.

The builddeb script has some hardcoded references to Linux version 2.6
which is ancient. Drop Provides as the virtual packages provided are not
useful anymore. Leave the Provides for linux-kernel-headers, as someone
might still be referring to it.
While at it, updated copyright date and drop Standards-Version: since
the package isn't Debian Standards compliant anyways.
