puffin: restructure the gyp file.

This fixes an asan test failure around some c++ objects being defined multiple
times. But it does more than that. It restructures the gyp files to mostly work
with static_libraries and only create shared libraries for export use.

TODO(ahassani): Describe the directory structure and how-tos.

Glossary

  • Alphabet A value that occurs in the input stream. It can be either a literal:[0..255], and end of block sign [256], a length[257..285], or a distance [0..29].

  • Huffman code A variable length code representing the Huffman encoded of an alphabet. Huffman codes can be created uniquely using Huffman code length array.

  • Huffman code array An array which an array index identifies a Huffman code and the array element in that index represents the corresponding alphabet. Throughout the code, Huffman code arrays are identified by vectors with postfix hcodes_.

  • Huffman reverse code array An array which an array index identifies an alphabet and the array element in that index contains the Huffman code of the alphabet. Throughout the code, The Huffman reverse code arrays are identified by vectors with postfix rcodes_.

  • Huffman code length The number of bits in a Huffman code.

  • Huffman code length array An array of Huffman code lengths with the array index as the alphabet. Throughout the code, Huffman code length arrays are identified by vectors with postfix lens_.
