code review and simplification

backport of 2.5 driver changes

the new HEAD

compatibility crap for kernels from the stone age

- use list_for_each_safe() again when modifying the lists -- this caused
   segfaults on 2.4.10 kernels

- add MODULE_XXX() macros to dvb_demux to suppress warnings at module load time

- handle av7110_irq in tasklet. The spinlock there might be a bit paranoid,
   we can check and beautify this later.

- wait_for_debi_done_irq() is obsolete now, use wait_for_debi_done() everywhere

- suppress av7110_ir debug messages by default

use down_interruptible where possible to fix driver unloading problems

more restrictive mutex locking

- removed the static device table from dvbdev.c, replaced by a list, we don't
   have any limit for the number of devices now.

   Since the Nokia API specifies that each open() call for a demux device
   allocates a new filter we can't use the file->private_data pointer to
   save the dvbdev struct, but have to search our device list linearly for
   each open/ioctl/release call. Should not be a real problem since we will
   rarely have more than a few DVB devices, but anyway - the code is ugly.

   Did I ever told you that the Nokia API sucks?

- put all EXPORT_SYMBOL() macros in dvb_ksyms.c and av7110_ksyms.c,
   now we don't have to build the whole driver from scratch when we touch
   a file exporting symbols...

the not yet working cable frontend are not a bug but a missing feature.
That rev2.1 support is broken is just not true, I have a rev2.1 card with
Alps BSRU6 tuner here, it's just working fine. What card exactly is not
working? (what frontend?)

For the disable-demux-before-tuning/enable-again-whe-TS-is-in-sync we have
a clean framework using the frontend notifiers now, the AV7110 just has to
call the register functions...

I'll care about these issues next week.

 - av7110: introduced something like a av7110/saa7146 namespace

 - ported saa7146 i2c driver to the new internal driver API, fixed
    problems with concatenated messages

 - tested and fixed Alps BSRU6, BSRV2, Grundig 29504-401 frontend code

 - initialize dvb device directory when initializing the DVB bridge

 - ported DiSEqC, 13/18V and 22kHz stuff to the new frontend API

 - ported szap and tzap

 - some new tiny test utilities (setpid, set22k, setvoltage, diseqc)

 - DMX_SATELLITE_FE, DMX_CABLE_FE and DMX_TERRESTRIAL_FE in demux.h are gone,
    defined DMX_FRONTEND_0, DMX_FRONTEND_1, DMX_FRONTEND_2 and DMX_FRONTEND_3

there are still a lot of FIXME's and debug messages, but the stuff is basically
working...

DiSEqC 2.0 related frontend API changes + some files that got lost in my last commit

new fronten stuff by Holger Waechtler
user interface not tested, probably does not
work as it is right now

use dvb_frontend_old.* for old interface

file dvb_i2c.c was initially added on branch NEWSTRUCT.
