Since Kconfig.sound is processed by make_kconfig.pl like all the other
Kconfig files, it was getting put into v4l/Kconfig twice. Once from a
source directive v4l/Kconfig and again when it was processed by the
script.

Create a symlink, v4l/oss, that points back to the v4l directory. This
way code that includes "oss/something.h" will find the header files it
wants (which has been linked to from v4l). The link will be created only
if it doesn't exist and deleted by distclean.

A subtle bug in the code that changed Kconfig depends expressions into
Perl expressions would keep changes to Kconfig variables from
propagating. The subroutine was supposed to change a _copy_ of the
expression from Kconfig to Perl syntax, but was changing the expression
itself.

The VIDIOC_G_SLICED_VBI_CAP needs to receive the v4l2_buf_type field before
it can return a result. Hence this ioctl must be IOWR, not IOR. Since this
ioctl is still marked experimental we can make this change.

VIDIOC_S/G_CROP is now handled by v4l2-ctl. The v4l2_buf_type is now filled in
in VIDIOC_G_SLICED_VBI_CAP. Several test tools now compile when v4l1 API is
disabled.

Both .config and Kconfig are created at the same time by the same
program, make_kconfig.pl. make does not understand the concept of
a program which creates two targets and cannot handle this properly.
Everything works with this patch, but in some cases make -j will run
make_kconfig.pl twice at the same time. This works, one script will just
overwrite the output of the other, but it looks bad. Without make -j,
everything works as it should and make_kconfig.pl isn't run more than it
needs to be.

Restructure make_kconfig.pl and clean the code up some more.
The dependency tracking code is rewritten. This version converts the
"depends on" and "select X if" lines into Perl expressions, which are
then evaluated. This way all complex expressions are handled correctly.
Dependencies are tracked recursively until all are found. "select" lines
with an "if" clause are handled correctly; the selected variable is only
required when the "if" clause is true.
Another improvement is that hex/string/int variables that don't have
their dependencies met will not appear in the .config file. They aren't
supposed to.
make_kconfig will fail with an error message if MODULES is turned off in
the Kernel's config, as building out of tree makes no sense in that
situation.

The script which combines the individual Makefils into Makefile.media
would include a Makefile each time it was referenced. This caused some
Makefiles to get included multiple times.
Also print comments in Makefile.media with the names of the Makefiles that
are being included.

links is a phony target, so it is always remade. The config targets
don't need the source links, so there is no need for them to have links
as a depenedency.

The make_makefile.pl script is re-written. The old one was nasty. This
one will correctly handle Makefile lines that are continued with a
backslash. It will also generate a dependency list of the Makefile used
to create Makefile.media. This way if any change, Makefile.media will be
automatically re-made by make.
The whole business where make_makefile.pl would call make_kconfig.pl is
removed.
The underlying logic of the main Makefile is completely changed. Make
has a feature where it will make sure any included files are up-to-date,
and then restart itself if any were updated. We now take advantage of
this feature.
Detect when make is building only targets which do not need include files
like .myconfig or Makefile.media, and don't include them in those cases.

Add the ability to the make_kconfig.pl script to create a file
named ".kconfig.dep" which can be included in a Makefile and defines the
dependencies of the v4l/Kconfig file. That is, all the individual
Kconfig files that were used to make it.
Added a rule to v4l/Makefile to remake Kconfig when needed, and include
.kconfig.deps to get Kconfig's dependencies. Adjust the config targets
so that they depend on Kconfig, rather than including the commands to
create Kconfig in the config targets' scripts. The config targets no
longer depend on .version, as they don't need it themselves. Rather,
it's Kconfig that needs .version, so it's made one of Kconfig's
dependencies.
Add Kconfig as a dependency to .myconfig, it should be there since the
make_myconfig.pl script uses Kconfig.
Now if you change any of the Kconfig files, the v4l/Kconfig file will
automatically get remade. This will in turn cause .myconfig to be
re-made, and any new options will appear in .myconfig (turned off).
Ideally this should trigger some kind of oldconfig system to update
.config.
Fix the .version rule so that instead of re-creating .version every time,
it is only created when it didn't already exist. Since Kconfig depends
on .version, it was getting re-created every time too. If .version
existed, it would just get re-created to the same thing anyway.
Stop echoing the echo srcdir command itself and don't echo anything if
SRCDIR is blank.

New code to read the Kernel's (or v4l-dvb's) '.config' file. This
replaces the code that used to read the config.h/autoconf.h file. In
2.6.18 the autoconf.h file no longer mentions options set to 'n' at all,
while .config has a comment line for each disabled option. Reading
.config is easier and gives us a list of the disabled options.
Restructure the code for reading '.version' too.

This script will read a Linux Kernel style Makefile tree and produce an
overview of the build process.
It produces three lists which show to associations of:
1. Kconfig variables to kernel module(s) built
2. Kernel modules to source file(s) that make them
3. Kconfig variables to source file(s) built
It can also check the Makefiles for various errors and warnings.

On SAA711x datasheets, registers are referenced by its numbers.
So, it is better to keep the number at register name. This way, it is
easier to seek that register at datasheet. Also, the alias helps to identify
what the meaning for each register.

Put static inline usb_to_input_id() inside compat.h for pre 2.6.13. This
needs linux/usb.h to be included first! Drivers that need
linux/usb_input.h compatibility must include linux/usb.h before they
include compat.h. There is just no way around it. linux/usb.h cannot be
unconditionally included in compat.h because that will break other,
non-usb, drivers.

Adjust temporal filter if necessary. The problem with the temporal
filter is that it works well with full resolution capturing, but
not when the capture window is scaled (the filter introduces
a ghosting effect). So if the capture window changed, and there is
no updated filter value, then the filter is set depending on whether
the new window is full resolution or not.
For full resolution a setting of 8 really improves the video
quality, especially if the original video quality is suboptimal.
Also report VBI Format in VIDIOC_LOG_STATUS, it was missing.
