lrint is faster and conveys the intent better here. It is safe as long int has
at least 32 bits.

If it is negative, it can cause the byte position to move backwards in
avio_skip, which in turn makes sm_size negative and thus size larger
than the size of the packet buffer, causing invalid writes in avio_read.
Also fix potential overflow of avio_tell(bc) + value_len.

This is used to check if the input buffer is large enough, so if this
overflows it can cause a false negative leading to a segmentation fault
in bytestream2_get_bufferu.

In the code we keep using logo_x2-1 and logo_y2-1 rather than logo_x2
and logo_y2 themselves. Define them to be what we need instead, to avoid
the repeated subtractions.

This macro unconditionally used out[-1], which causes an out of bounds

More don't fit into the integer output.
Also use get_bits_long, since get_bits only supports reading up to 25
bits, while get_bits_long supports the full integer range.

The type of last_frame_pb_count was chosen to be an int since overflow
is impossible (the spec says the maximum bits per frame is 6144 per
channel and the encoder checks for that).

exp2 is faster.
It may be possible to optimize further; e.g the exponents seem to be
multiples of 0.25. This requires study though.
