Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

Creating a Debian package without CONFIG_DEBUG_INFO produces
a warning that no debug package was created.

This patch excludes the debug package from the control file,
if no debug package is created by this configuration.

Cross compiling the x86 kernel on a non-x86 build machine produces
the following error when CONFIG_UNWINDER_ORC is enabled, regardless
of whether libelf-dev is installed or not.

  dpkg-checkbuilddeps: error: Unmet build dependencies: libelf-dev
  dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
  dpkg-buildpackage: warning: (Use -d flag to override.)

Since this is a build time dependency for a build tool, we need to
depend on the native version of libelf-dev so add the appropriate
annotation.

We've missed the dependency to rsync, so build fails on
minimal containers.

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).

  Thus it would be more foolproof to explicitly use 1.0 (as we always
  did) than to rely on dpkg-source's defaults.

* In a similar vein, debian/rules is not made executable by mkdebian,
  and dpkg-source warns about that but still silently fixes the file.
  Let's be explicit once again.

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.

This might be a kind of bike-shed, but I personally prefer grep'able
code.

I often do 'git grep CONFIG_FOO' instead of 'git grep FOO' when I
want to know where that CONFIG option is used.

This makes code longer, but I hope this is acceptable level.

bison/flex is now needed always for building for kconfig. Some build
dependencies depend on kernel configuration, enable them as needed:

- libelf-dev when UNWINDER_ORC is set
- libssl-dev for SYSTEM_TRUSTED_KEYRING

Since the libssl-dev is needed for extract_cert binary, denote with
:native to install the libssl-dev for the build machines architecture,
rather than for the architecture of the kernel being built.

'$(MAKE) KBUILD_SRC=' changes the working directory back and forth
between objtree and srctree.

It is better to recurse to the top-level Makefile directly.
