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.

From: Trent Piepho <xyzzy@speakeasy.org>
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.

This fixes the patch failure when using the "make kernel-links" build method.
We no longer have to patch videodev.h to include compat.h for the in-kernel
build using the v4l-dvb development repository, as the individual card drivers
that need compat.h are already including it.

Instead of reading linux/config.h, read linux/autoconf.h to get the
kernel's configuration. The former file has been obsoleted.
In Kconfig 'select' lines, ignore the 'if' clause if one exists. This is
not a permanent solution to correctly parse and evaluate Kconfig files.
That is much harder, this will get building working again now.

The code to compare kernel versions was wrong, it would think 2.7.1 was
older than 2.6.10 because 1 < 10. Fixed.
Changed code to not require all options to be defined in versions.txt.
It was necessary before only because of the way make_myconfig.pl worked,
but that script has changed. Driver sub-options can be omitted from
versions.txt, unless they somehow need a newer kernel than the driver
itself.
In fact, most of the drivers themselves could be removed from
versions.txt, and only put in if there is an actual reason.

When the make commit checks for whitespace errors, it will save a copy of
the changes it makes to $(TMP)/v4l_hg_whitespace. The prep_commit_msg.pl
script will look for this file and include a note in the prepared commit
message with diffstat output.
The changes that scripts/cardlist might make are not included, but that
can be added later.
The prep_commit_msg.pl script is effectively totally re-written. This one
will try some extra stuff to some up with the user's e-mail, such as
looking in the ~/.hgrc file.
The Makefile is changed so that temporary files created by make commit
and make whitespace will honor the $TMP environment variable, if set.

Most V4L/DVB hg tree users are just compiling using kernel headers.
This is bad, due to:
1) the lack of support for make *config
2) the kernel itself have unknown patches from the distros
Anyway, it is useful to provide they some support.
This patch provides a "hack" for such users, by checking if the
sound/oss/aci.h file is present under kernel tree. If not, it will
disable miropcm20 and print a warning about the usage of a kernel-headers
only package.

Faster script that doesn't use any temporary files. The old one
would also miss cleaning four spaces in a row in places where
it would clean one to eight spaces. Has two options:
fast
Only clean whitespace in files Hg thinks are modified or added. Used by
make whitespace and much (about 100x) faster.
manifest
Clean all files controlled by Hg, using "hg manifest"
The default with no options is the old behaviour, clean all files under
the linux directory, except CVS files.

rmmod.pl is a "smart" script: it does:
1) Check, for each found module on v4l, the correct order for each
module;
2) Check any dependencies for out-of-tree modules;
3) rmmod/insmod at the correct order;

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.
