   *
   * On fail call [[Deflate#onEnd]] with error code and return false.
   *
   * We strongly recommend to use `Uint8Array` on input for best speed (output
   * array format is detected automatically). Also, don't skip last param and always
   * use the same type in your code (boolean or number). That will improve JS speed.
   *
   * For regular `Array`-s make sure all elements are [0..255].

  /*
     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.

     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.

   * - `raw` (Boolean) - do raw inflate
   * - `to` (String) - if equal to 'string', then result will be converted

   *
   * Decompress `data` with inflate/ungzip and `options`. Autodetect
   * format via wrapper header by default. That's why we don't provide
   * separate `ungzip` method.
   *
   * Supported options are:
   *
   * - windowBits
   *
   * [http://zlib.net/manual.html#Advanced](http://zlib.net/manual.html#Advanced)
   * for more information.
   *
   * Sugar (options):
   *
   * - `raw` (Boolean) - say that we work with raw stream, if you don't wish to specify
   *   negative windowBits implicitly.
   * - `to` (String) - if equal to 'string', then result will be converted
   *   from utf8 to utf16 (javascript) string. When string output requested,
   *   chunk length can differ from `chunkSize`, depending on content.
   *
   *
   * ##### Example:
   *
   * ```javascript
   * var pako = require('pako')
   *   , input = pako.deflate([1,2,3,4,5,6,7,8,9])
   *   , output;
