package/lzma-alone: new package

Browse Source 
This new package provides "lzma_alone" host binary based on the original
LZMA SDK. It provides few extra options when compared to the LZMA Utils
/ XZ Utils project "lzma" binary (already packaged as the "lzma").

This packaging schema (LZMA SDK with lzma -> lzma_alone rename) follows
Debian's solution. Please note that Debian also uses LZMA SDK for the
base "lzma" tool which may be considered for Buildroot too - as an
independent change. Similar packaging is also used by Ubuntu & Arch.

lzma_alone is a requirement for preparing firmware images for some
Broadcom based home routers with a picky CFE bootloader. It has limited
LZMA support and building compatible images requires specifying
dictionary size and lc/lp/pb LZMA values manually.

Version 9.22 is used as it's the last release using .tar.bz2 format. The
same version is used by Debian.

help
LZMA has two well-known command-line tools:
1. lzma from LZMA SDK
2. lzma from XZ Utils (previously LZMA Utils)
This package provides the former one which:
1. Gives more control over compression parameters
2. Gets named lzma_alone to allow coexistence
This tool may be used to prepare firmwares for bootloaders
with limited LZMA support.
E.g. Broadcom's CFE bootloader for MIPS BCM47xx devices is
known to fail to boot images using LZMA compression with
dictionary.
