   sometimes blocks on read() after returning from select().

(da big courmischage)

long delay because we only receive PAT at the start), but we increase each time we read
data until 20. This decrease the load (more than 50% for me) while kepping low start up delay.

  Reconfigure the frontend if no lock is acquired in 10s.

  - Rewrote QPSK frontend tuning functions, after reading the doc - it
    should hopefully fix the infamous "Operation not permitted" problem.
  - Permanently monitor the frontend status, and reinit it if it crashes.
  - New --dvb-high-voltage option for very long cables.
  - Moved all EN 50 221-related code from ts.c to en50221.c. We no longer
    need the --ts-capmt-sysid option because the sysid is determined
    automatically from the CAM.
  - Also changed the way we send the CAPMTs to the CAM, hoping to fix a bug
    with Aston professional CAMs which all of sudden stop descrambling
    a program after a few days.

* Each module can declare a "human-readable short name" with set_name
* Modules are sorted by category (set_category, set_subcategory).
  Modules configs can be separated by set_section()
* Separated audio-filter and audio-visual
* Separated extraintf and control
* New command and widget : add_module_list() for comma-separated modules
* Vfilters now use "," as separator

   native support for CAM modules (without using an external program).
   When used in conjunction with --programs, it also allows to descramble
   several services with one professional CAM.

  of linuxtv drivers. We currently only descramble one channel (this will
  change in the near future). Also fixed a few demux-related bugs.

* Add ACCESS_SET_PRIVATE_ID_STATE to the list of every access plugin
* msg_Err -> msg_Warn for unimplemented Control queries

mode (else I still need to hack ts demuxer).

I haven't tried :)

* include/modules_inner.h, include/modules.h: added a shortname field to the module declaration section.
* modules/access/*: added a shortname to a few modules.

  of atoi, because atoi assumes base 10.
* modules/access/dvb/access.c: New --dvb-caching option.
* modules/mux/mpeg/ts.c: Cosmetics.

             - fix small memory leak on closing of dvb plugin.
dvb/linux-dvb.c - remove astray spaces
                - always empty the event queue before FE_SET_FRONTEND and FrontendCheck(). 
                  dvbstream does the same for OFDM and QAM. 

Summary: 
   DVB-C is working (did a few tests) 
   DVB-T not tested. 
   Using polarization=A doesn't work anymore INVERSION_AUTO is not honered for tuning. 
   SEC_VOLTAGE_OFF is missing when using latest code DVB-1.1.7 from http://www.metzlerbros.org/dvb/index.html. While include/linux/dvb/version.h is not updated and still reflects this API version: #define DVB_API_VERSION 3

* modules/access/dvb/access.c: Removed the temporary --dvb-program hack
* modules/demux/ts.c: New --ts-silent option to avoid complaints about
  encrypted packets (especially useful with --sout-all for streaming a part
  of a transponder).

  - new options (now prepended with --dvb) :
     --dvb-program : to work around the non-working --program
     --dvb-inversion : to (optionally) specify the inversion, which is not
                       the same as polarization
     --dvb-budget-mode : if you have a budget card this will set a filter
                         on 0x2000, meaning all PIDs will be returned by
                         the driver. The budget-mode is compatible with demux2.
     --dvb-satno : to specify a sat number in the diseqc system
     --dvb-voltage : to specify the voltage of the LNB (0 is a permitted
                     value in special configurations)
     --dvb-tone : to enable/disable the 22kHz tone (by default it is sent
                  if frequency >= lnb-slof)
  - fixed a handful of QPSK tuning bugs, especially the diseqc was not
    working and frequencies above 11700 couldn't be tuned to.
  - the modules now uses the inherited object variables for its
    configuration.
  - symbol-rate= url option is now srate= for consistency with the
    configuration variable.
  - all linux-dvb specific code is now in linux_dvb.c. access.c contains
    only code which could be reused on other platforms.
  - better keep track of demux file descriptors (especially useful on
    limited boards).
  - do not block in read() when no data is available.
  - fixed msleep() calls (reminder : mtime_t is in _microseconds_).

I didn't test the QAM and OFDM variants, so please report.

		better debug information
dvb/dvb.c	debug message beautifying
dvb/qpsk.c	textual changes

- Make sure that lnb-lof1 and lnb-lof2 can be overriden by the commandline syntax frequency=xx:lnb-lof1=xx:lnb-lof2=xx
- Added value {A,a} to polarization=xx to force INVERSION_AUTO
- Sanatized a few error messages

- cleanup of messages
- adding status events messages from frontend
- separated tuning for DVB-S, DVB-T and DVB-C into seperate functions.

Fix bug for DVB-T tuning. The code always used default upper and lower frequencies from DVB-S for DVB-T, but for DVB-T they could very well be different. Now using --lnb-lof1, --lnb-lof2 and --lnb-slof values are used by default instead. This make it overrideable on the commandline.
