This mainly changes the way make_kconfig.pl handles config options that
require a newer kernel, as defined by versions.txt. Currently it outputs
a blank config stanza defining the variable and setting it to 'n'. These
show up as mysterious un-named grayed out options in xconfig, or just
don't appear at all in menuconfig.
The new method outputs an extra config stanza to the top of v4l/Kconfig,
VIDEO_KERNEL_VERSION. This boolean variable defaults to 'n', and if
enabled, allows selecting drivers that are listed as needing a newer
kernel. Config options that need a newer kernel still apear in
v4l/Kconfig with their names and help text, but they now have an
additional dependency on VIDEO_KERNEL_VERSION, and an extra bit in the
help text warning that they need a newer kernel. They will appear greyed
out in xconfig, but will still have their proper names and help text. If
the user turns VIDEO_KERNEL_VERSION on, then they can be enabled. The
kernel version in versions.txt tends to be somewhat conservative.
The default v4l/.config file generated by make_kconfig.pl will have these
options set to no, instead of yes/module as it did before.
make_noconfig.pl will no longer look at versions.txt, or deal with kernel
version detection. It will get a list of all config options by reading
v4l/Kconfig, and produce .myconfig by setting all bool/tristate options
to their value from v4l/.config, or 'n' if not listed.
A few bugs have been fixed, and the regexs adjusted. They were making a
few mistakes before, or were otherwise flawed. The scripts do more error
checking that the files they parse conform to the expected syntax.

Some systems use a previous config information to generate
a default config. This seems to cause troubles on some
systems. This patch fixes compilation for AV7110 firmware
inside V4L/DVB tree.

Now, make_kconfig.sh will check for boolean/tristate config
vars and handle it properly.
Also, make allyesconfig/allmodconfig will use make_kconfig.sh
to generate .myconfig instead of conf -m. This way, make all will
not require priviledges at kernel tree.
write access to kernel tree is still required for make menuconfig/
make xconfig/make qconfig.

Without this fix, CONFIG_DVB_AV7110_OSD=y and CONFIG_DVB_AV7110_FIRMWARE=y
were ignored in v4l/Makefile because make_noconfig.pl set them to
"CONFIG_DVB_AV7110_... = m".

make all will do allmodconfig before compiling

Previously, tree building were based on Make.config. This file contained all
compiling stuff. Also, v4l/Makefile contained all drivers that should be
copiled, replicating the rules of all other Makefiles under linux.
Now, make will rely on linux/*/Makefile to compile the modules. This approach
allows usage of Kconfig files, allowing partial compilations.
Newer makefile commands introduced:
make allmodconfig - Selects all stuff to be compiled as module;
make config - Selects packages via text interface;
make xconfig - Selects packages via qt interface;
make gconfig - selects packages via gtk interface.
for config, xconfig and gconfig to be used, those scripts needs to be previously
compiled at kernel. So, user needs to use those commands previously at kernel tree.
