/*
   Decode literal, length, and distance codes and write out the resulting
   literal and match bytes until either not enough input or output is
   available, an end-of-block is encountered, or a data error is encountered.
   When large enough input and output buffers are supplied to inflate(), for
   example, a 16K input buffer and a 64K output buffer, more than 95% of the
   inflate execution time is spent in this routine.

   Entry assumptions:

        state.mode === LEN
        strm.avail_in >= 6
        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.

 when a window is already in use, or when output has been written during this

 It is also called to create a window for dictionary data when a dictionary

 Providing output buffers larger than 32K to inflate() should provide a speed
 advantage, since only the last 32K of output is copied to the sliding window
 upon return from inflate(), and since all distances after the first 32K of
 output will fall in the output data, making match copies simpler and faster.
 The advantage may be dependent on the size of the processor's data caches.

   Process a set of code lengths to create a canonical Huffman code.  The
   code lengths are lens[0..codes-1].  Each length corresponds to the
   symbols 0..codes-1.  The Huffman code is generated by first sorting the
   symbols by length from short to long, and retaining the symbol order
   for codes with equal lengths.  Then the code starts with all zero bits
   for the first code of the shortest length, and the codes are integer
   increments for the same length, and zeros are appended as the length
   increases.  For the deflate format, these bits are stored backwards
   from their more natural integer increment ordering, and so when the
   decoding tables are built in the large loop below, the integer codes
   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
   the minimum and maximum length codes, determining if there are any
   codes at all, checking for a valid set of lengths, and looking ahead
   at length counts to determine sub-table sizes when building the
   decoding tables.

   Create and fill in decoding tables.  In this loop, the table being
   filled is at next and has curr index bits.  The code being used is huff
   with length len.  That code is converted to an index by dropping drop
   bits off of the bottom.  For codes where len is less than drop + curr,
   those top drop + curr - len bits are incremented through all values to
   fill the table with replicated entries.

   root is the number of index bits for the root table.  When len exceeds
   root, sub-tables are created pointed to by the root entry with an index
   of the low root bits of huff.  This is saved in low to check for when a
   new sub-table should be started.  drop is zero when the root table is
   being filled, and drop is root when sub-tables are being filled.

   When a new sub-table is needed, it is necessary to look ahead in the
   code lengths to determine what size sub-table is needed.  The length
   counts are used for this, and so count[] is decremented as codes are
   entered in the tables.

   used keeps track of how many table entries have been allocated from the
   provided *table space.  It is checked for LENS and DIST tables against
   the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
   the initial root table size constants.  See the comments in inftrees.h
   for more information.

   sym increments through all symbols, and the loop terminates when
   all codes of length max, i.e. all codes, have been processed.  This
   routine permits incomplete codes, so another loop after this one fills
   in the rest of the decoding tables with invalid code markers.

// a transform stream is a readable/writable stream where you do
// something with the data.  Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored.  (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation.  For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes.  When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up.  When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer.  When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks.  If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk.  However,
// a pathological inflate type of transform can cause excessive buffering
// here.  For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output.  In this case, you could write a very small
// amount of input, and end up with a very large amount of output.  In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform.  A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.
