97679fa5a1 Google Code Issue 155: lz4 cli should support sparse file
https://code.google.com/p/lz4/issues/detail?id=155

This is experimental implementation. Just a proof of concept.
It works Linux and Windows.

# Build

To build experimental version, define 'LZ4IO_ENABLE_SPARSE_FILE' like the following command :

    make lz4programs 'CFLAGS=-O3 -DLZ4IO_ENABLE_SPARSE_FILE=1'
    ./programs/lz4 -h

You will see "EXPERIMENTAL_SPARSE_FILE" as lz4 revision :

    "*** LZ4 command line interface 64-bits EXPERIMENTAL_SPARSE_FILE, by Yann Collet (...) ***"

# Experiment

This experimental version adds option "-x" for sparse file for decompression.
You can use this option like this :

    ./programs/lz4 -9 -f my-file
    ./programs/lz4 -d -f -x my-file.lz4 my-file.lz4.out
    cmp my-file my-file.lz4.out

69dc85b8ab Large decompression speed improvement for GCC 32-bits. Thanks to Valery Croizier !
LZ4HC : Compression Level is now a programmable parameter (CLI from 4 to 9)
Separated IO routines from command line (lz4io.c)
Version number into lz4.h (suggested by Francesc Alted)
