/*
This function inserts bits in the inflate input stream. The intent is
that this function is used to start inflating at a bit position in the
middle of a byte. The provided bits will be used before any bytes are used
from next_in. This function should only be used with raw inflate, and
should be used before the first inflate() call after inflateInit2() or
inflateReset(). bits must be less than or equal to 16, and that many of the
least significant bits of value will be inserted in the input.
If bits is negative, then the input stream bit buffer is emptied. Then
inflatePrime() can be called again to put bits in the buffer. This is used
to clear out bits leftover after feeding inflate a block description prior
to feeding inflate codes.
inflatePrime returns Z_OK if success, or Z_STREAM_ERROR if the source
stream state was inconsistent.

/*
This function returns two values, one in the lower 16 bits of the return
value, and the other in the remaining upper bits, obtained by shifting the
return value down 16 bits. If the upper value is -1 and the lower value is
zero, then inflate() is currently decoding information outside of a block.
If the upper value is -1 and the lower value is non-zero, then inflate is in
the middle of a stored block, with the lower value equaling the number of
bytes from the input remaining to copy. If the upper value is not -1, then
it is the number of bits back from the current bit position in the input of
the code (literal or length/distance pair) currently being processed. In
that case the lower value is the number of bytes already emitted for that
code.
A code is being processed if inflate is waiting for more input to complete
decoding of the code, or if it has completed decoding but is waiting for
more output space to write the literal or match data.
inflateMark() is used to mark locations in the input data for random
access, which may be at bit positions, and to note those cases where the
output of a code may span boundaries of random access blocks. The current
location in the input stream can be determined from avail_in and data_type
as noted in the description for the Z_BLOCK flush parameter for inflate.
inflateMark returns the value noted above, or -65536 if the provided
source stream state was inconsistent.
