Subtracting a (positive) value from the address of an array violates
C99 section 6.5.6:

  If both the pointer operand and the result point to elements of the
  same array object, or one past the last element of the array object,
  the evaluation shall not produce an overflow; otherwise, the
  behavior is undefined.

necessarily int.

HAVE_THREADS is set in config.h if pthreads or w32threads is
available, which presumably the proper condition here.

Also fixes undefined behaviour in preprocessor directives.

This makes sure the previously always installed public header
lzo.h is installed if the LZO functionality is enabled.

This was previously implicitly done in ff_raw_read_header().
Fixes fate tests with pcm input.

avio_size() reports the filesize which returns 0 for /dev/null.
avio_tell() reports the current position.

Also handle errors from avio_tell().

Fixes CID700635, CID700636 and CID732274.

It is not used anymore and is a kludge.

The code shared is not actually shared with anything else.

ff_raw_read_header is used only for this demuxer for video.

The function is used elsewhere and does not belong with the LZO code.

Avoids memleaks with audio when extended_data is nontrivial and the user
doesn't reset the frame.
Shouldn't have any effect for video for now, but might be useful in the
future.
