88d80cb97528d52dac3178cf5393d6095eca6200 changed the type of PutBitContext.BitBuf to uint64_t; it used to be an uint32_t. While said structure is not public, it is nevertheless used by certain avpriv functions and therefore crosses library boundaries: avpriv_align_put_bits and avpriv_copy_bits were used in other libraries in release 4.3 (and at the time of 88d80cb9) and so this commit broke ABI. This commit mitigates the trouble caused by this by using an uint32_t again, but only for the 4.4 release branch and not the master branch, as doing so for master, would break the ABI of master again, although it is very unlikely that anyone would be helped by this (there don't seem to be any users that combine libavcodec built from master and libavformat from an old release: otherwise we would have received bug reports about said ABI break).
