-/*************************************************************************
-* Name:        lz.c
-* Author:      Marcus Geelnard
-* Description: LZ77 coder/decoder implementation.
-* Reentrant:   Yes
-* $Id$
-*
-* The LZ77 compression scheme is a substitutional compression scheme
-* proposed by Abraham Lempel and Jakob Ziv in 1977. It is very simple in
-* its design, and uses no fancy bit level compression.
-*
-* This is my first attempt at an implementation of a LZ77 code/decoder.
-*
-* The principle of the LZ77 compression algorithm is to store repeated
-* occurrences of strings as references to previous occurrences of the same
-* string. The point is that the reference consumes less space than the
-* string itself, provided that the string is long enough (in this
-* implementation, the string has to be at least 4 bytes long, since the
-* minimum coded reference is 3 bytes long). Also note that the term
-* "string" refers to any kind of byte sequence (it does not have to be
-* an ASCII string, for instance).
-*
-* The coder uses a brute force approach to finding string matches in the
-* history buffer (or "sliding window", if you wish), which is very, very
-* slow. I recon the complexity is somewhere between O(n^2) and O(n^3),
-* depending on the input data.
-*
-* There is also a faster implementation that uses a large working buffer
-* in which a "jump table" is stored, which is used to quickly find
-* possible string matches (see the source code for LZ_CompressFast() for
-* more information). The faster method is an order of magnitude faster,
-* and also does a full string search in the entire input buffer (it does
-* not use a sliding window).
-*
-* The upside is that decompression is very fast, and the compression ratio
-* is often very good.
-*
-* The reference to a string is coded as a (length,offset) pair, where the
-* length indicates the length of the string, and the offset gives the
-* offset from the current data position. To distinguish between string
-* references and literal strings (uncompressed bytes), a string reference
-* is preceded by a marker byte, which is chosen as the least common byte
-* symbol in the input data stream (this marker byte is stored in the
-* output stream as the first byte).
-*
-* Occurrences of the marker byte in the stream are encoded as the marker
-* byte followed by a zero byte, which means that occurrences of the marker
-* byte have to be coded with two bytes.
-*
-* The lengths and offsets are coded in a variable length fashion, allowing
-* values of any magnitude (up to 4294967295 in this implementation).
-*
-* With this compression scheme, the worst case compression result is
-* (257/256)*insize + 1.
