A user who wishes to use default error concealment cannot set the
AV_EF_CRCCHECK flag because not every CRC in every format is a
reliable indicator of bitstream damage. In some formats crcrs
can be nonsensical in absence of any damage. We thus add the
AV_EF_CAREFUL flag in addition to the AV_EF_CRCCHECK flag to
allow a user to enable this reliable CRC check without having to
enable all CRC checks in all formats.

Fix regression introduced in 2b53e69.

Return the whole packet as consumed in this case and not the size the
packet should have had. Move the insufficient data check into the for
condition to fix a ISO C90 error on bigendian.

Thus we can check for 4 being available.
If the next block is skiped we need 4 bits to encode the skip. If the
next block is not skiped then we need 1 bit for the skip code and
at least 3 bits for the block.

This groups the encode/decode parts under single ifdefs and
eliminates the encode_init() function as it merely calls
common_init().  Also fix whitespace in moved code.
