Major cleanup: the goal is to get rid of the budget card <=> saa7146.o <=> videodev.o dependency,

so we can later split up the av7110 driver into a av7110 and budget card driver.

I tested this on 2.4.18-3 (original RedHat 7.3 kernel) and 2.5.53.

Changes in detail:

saa7146:
- fixed the unitialised timer warnings
- split saa7146.o into saa7146.o and saa7146_vv.o:
  all videodev (ie. v4l) related stuff is now encapsulated in saa7146_vv.o.
  the extension (ie. mxb or dvb-ttpci) now has to make sure to register the v4l
  devices via helper functions provided by saa7146_vv

mxb:
- changes to make the driver compile with the new saa7146 and saa7146_vv parts
- fix the vbi bypass issue for MXBs with saa7146, rev. 1 card

av7110:
- changes to make the driver compile with the new saa7146 and saa7146_vv parts
- some changes related to the upcoming av7110 <=> budget splitup, but they are
  commented out
- changed the saa7146 PAL values to experimental values that look good to me, but
  kept the old values as a comment. where are the original values from? there is
  a big black border on most channels on the left side which annoyed me...
- changed from video/generic_usercopy() to dvb_usercopy() and put this into the
  source code, not into compat.c
- moved the crc_32* stuff from compat.c to the source file where it is used
- now compat.[ch] was removed completely, all references were deleted from
  all other files.

other:
- updated the README and TODO files
- changed "makelinks" to remove alps_bsru6 stuff from kernel when making the symlinks
- fixed the build files in "build-2.4"
- fixed all other files needed for 2.5.x kernel build
