(cherry picked from commit 0a40ad27)

Signed-off-by: Jean-Paul Saman <jpsaman@videolan.org>

Using --enable-debug makes libdvbpsi too verbose. Instead use
RPM_BUILD_OPTS="-g -gdb3" rpmbuld -ta libdvbpsi-0.2.0.tar.gz to generate
a bujld with more debugging information.

- Added --libdir=%{_libdir} to configure
- Added --enable-debug to compile with debug symbols

Packagers and application developers should anticipate the following changes for libdvbpsi version 1.0.0:
- removal of struct dvbpsi_handle
- new struct dvbpsi_t (iso dvbpsi_handle)
- structure size changes, decoders share common members
- removal of printfs in libdvbpsi code
- adding message callback for error, warning and debugging messages

The API changes are needed to remove printfs from the library and to make the libdvbpsi API more consistent.

Update documentation information and fix structure somewhat.

Raise warnings to error level and break compilation.

Replace

  unsigned int i;
  for(i = 0; ...)

with

  for(unsigned int i=; ...)

Fixed compiler warning in function TSHandle(), which passed a 'const uint8_t *' into
dvbpsi_PushPacket() that expected a 'uint8_t *'.
