Default branch: MAIN

- Introduce the variable "readers" to "struct dvbdev". Some devices
might be opened read-only or read-write (even multiple times) and therefore
we need to keep track of the open count for "readers" and "writers"
separately.
- Follow this change in the generic_open() and close() functions for dvbdev
- Make the av7110 video device aware of RD_ONLY opens. If the device is
opened RD_ONLY, only poll() for events and the GET_...() IOCTLs can be called.

- add name field to struct dvb_adapter
- make it a const char* pointer

backport of 2.5 driver changes

C99 patches by <aschultz@apophis.eastlink.de>

the new HEAD

make room for the new HEAD trunk

compatibility crap for kernels from the stone age

less verbosity, switch to debug mode using module parameter dvbdev_debug=1

linux-2.4.6 compatibility cruft

use down_interruptible where possible to fix driver unloading problems

more restrictive mutex locking

 - link related object files together in order to get less kernel modules
 - link related object files together in order to get less kernel modules
 - configurable IR keymaps using /proc/av7110_ir
 - make frontend code a little less verbose
 - removed some old/unused stuff

some license string cleanups

tuning support for NOVA-CI (not tested)

 - put card identification into saa_core.c, pass a device string to
    dvb_register_adapter().
    (we still miss 2 vendor/device name pairs...)

 - use the priv field in struct videodev to store the av7110 pointer

 - use only a single instance of card number, only in struct dvb_adapter

 - use generic_usercopy() in dvb_generic_ioctl(), this saves some code

 - identify devices by adap_num, type, id triplets instead of minor id's,
    this removes any hardcoded limit for devfs systems.

 - devfs-only support can be enabled by defining CONFIG_DVB_DEVFS_ONLY

now we can use the private_data fields again, the device list has to be searched only once for no-devfs-systems, for devfs systems never

- 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.

- some more re-formatting wich crossed paths with Holgers changes

- fixed missing spinlock init in dvb_demux.c (same as in main branch)

- Nova "broken packets" fix (also see main branch)


bugs remaining from Holgers checkin:

- no cable cards

- Rev. 2.1 cards unusable
  old bug with active video PID during channel switching re-introduced

 - 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...
