+ Decode literal, length, and distance codes and write out the resulting

+ When large enough input and output buffers are supplied to inflate(), for

+ inflate execution time is spent in this routine.

+ strm.avail_out >= 258
+ start >= strm.avail_out
+ state.bits < 8
+
+ On return, state.mode is one of:
+
+ LEN -- ran out of enough output space or enough available input
+ TYPE -- reached end of block code, inflate() to interpret next block
+ BAD -- error in block data
+
+ Notes:
+
+ - The maximum input bits used by a length/distance pair is 15 bits for the
+ length code, 5 bits for the length extra, 15 bits for the distance code,
+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm.avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm.avail_out >= 258 for each loop to avoid checking for
+ output space.

+ Process a set of code lengths to create a canonical Huffman code. The

+ are incremented backwards.
+ This routine assumes, but does not check, that all of the entries in
+ lens[] are in the range 0..MAXBITS. The caller must assure this.
+ 1..MAXBITS is interpreted as that code length. zero means that that
+ symbol does not occur in this code.
+ The codes are sorted by computing a count of codes for each length,
+ creating from that a table of starting indices for each length in the
+ sorted table, and then entering the symbols in order in the sorted
+ table. The sorted table is work[], with that space being provided by
+ the caller.
+ The length counts are used for other purposes as well, i.e. finding
