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

+      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()

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