for implementing the TerrestrialDeliverySystemDescriptor in libdtv
for fixing setting the locking pid after a timed wait
for changing thread handling to make it work with NPTL ("Native Posix Thread Library")
for his 'autopid' patch which was helpful when implementing automatic
channel data gathering

instead of explicit 'dsyslog()' calls inside their Action() function in order
to support logging the thread ids.
- Added "Slovak Link" and "Czech Link" to 'ca.conf' (thanks to Emil Petersky).
However, 'ca.conf' is now pretty much obsolete due to the automatic CA handling.
- Mutexes are now created with PTHREAD_MUTEX_ERRORCHECK_NP, which makes the
'lockingTid' stuff obsolete (thanks to Stefan Huelswitt).
- Changed font handling to allow language specific character sets.

- Replaced 'libdtv' with 'libsi' (thanks to Marcel Wiesweg), which is thread
safe and can be used by multiple section filters simultaneously.

- Added 'cRwLock' to 'thread.[hc]'. Note that all plugin Makefiles need to
define _GNU_SOURCE for this to work (see the example plugin Makefiles and

sections, depending on where they are found in the PMT (thanks to Hans-Peter
Raschke for reporting this one). This should make SkyCrypt CAMs work.
- Now using the 'version number' of EPG events to avoid unnecessary work.
- Channel data is now automatically derived from the DVB data stream (inspired
by the 'autopid' patch from Andreas Schultz).
- The current channel is now automatically re-tuned if the PIDs or other settings
change. If a recording is going on on a channel that has a change in its
settings, the recording will be stopped and immediately restarted to use the
new channel settings.
- EPG events now use the complete channel ID with NID, TID and SID.
- Channel names in 'channels.conf' can now have a short form, as provided
by some tv stations (see man vdr(5)). Currently channels that provide short
names in addition to long ones are listed in the OSD as "short,long name",
as in "RTL,RTL Television". The short names will be used explicitly later.
- The Ca parameter in 'channels.conf' has been extended and now contains all the
CA system ids for the given channel. When switching to a channel VDR now tests
for a device that provides one of these CA system ids. The devices automatically
get their supported ids from the CI handler.
- The values in 'ca.conf' are currently without any real meaning. Whether or not
a channel with conditional access can be received is now determined automatically
by evaluating its CA descriptors and comparing them to the CA system ids
provided by the installed CAM. Only the special values 1-16 are used to assign
a channel to a particular device.
