This package contains the "liblzma" code from the "XZ Utils" package
which is declared to be in the public domain and as usual, this
software is provided "as is", without any warranty.
Below is the original licence information from the XZ Utils package.
----
XZ Utils Licensing
==================
Different licenses apply to different files in this package. Here
is a rough summary of which licenses apply to which parts of this
package (but check the individual files to be sure!):
- liblzma is in the public domain.
- xz, xzdec, and lzmadec command line tools are in the public
domain unless GNU getopt_long had to be compiled and linked
in from the lib directory. The getopt_long code is under
GNU LGPLv2.1+.
- The scripts to grep, diff, and view compressed files have been
adapted from gzip. These scripts and their documentation are
under GNU GPLv2+.
- All the documentation in the doc directory and most of the
XZ Utils specific documentation files in other directories
are in the public domain.
- Translated messages are in the public domain.
- The build system contains public domain files, and files that
are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
in the binaries being built.
- Test files and test code in the tests directory, and debugging
utilities in the debug directory are in the public domain.
- The extra directory may contain public domain files, and files
that are under various free software licenses.
You can do whatever you want with the files that have been put into
the public domain. If you find public domain legally problematic,
take the previous sentence as a license grant. If you still find
the lack of copyright legally problematic, you have too many
lawyers.
As usual, this software is provided "as is", without any warranty.
If you copy significant amounts of public domain code from XZ Utils
into your project, acknowledging this somewhere in your software is
polite (especially if it is proprietary, non-free software), but
naturally it is not legally required. Here is an example of a good
notice to put into "about box" or into documentation:
This software includes code from XZ Utils <http://tukaani.org/xz/>.
The following license texts are included in the following files:
- COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
- COPYING.GPLv2: GNU General Public License version 2
- COPYING.GPLv3: GNU General Public License version 3
Note that the toolchain (compiler, linker etc.) may add some code
pieces that are copyrighted. Thus, it is possible that e.g. liblzma
binary wouldn't actually be in the public domain in its entirety
even though it contains no copyrighted code from the XZ Utils source
package.
If you have questions, don't hesitate to ask the author(s) for more
information.

// Unaligned reads and writes //
////////////////////////////////
// The traditional way of casting e.g. *(const uint16_t *)uint8_pointer
// is bad even if the uint8_pointer is properly aligned because this kind
// of casts break strict aliasing rules and result in undefined behavior.
// With unaligned pointers it's even worse: compilers may emit vector
// instructions that require aligned pointers even if non-vector
// instructions work with unaligned pointers.
//
// Using memcpy() is the standard compliant way to do unaligned access.
// Many modern compilers inline it so there is no function call overhead.
// For those compilers that don't handle the memcpy() method well, the
// old casting method (that violates strict aliasing) can be requested at
// build time. A third method, casting to a packed struct, would also be
// an option but isn't provided to keep things simpler (it's already a mess).
// Hopefully this is flexible enough in practice.

// Aligned reads and writes //
//////////////////////////////
// Separate functions for aligned reads and writes are provided since on
// strict-align archs aligned access is much faster than unaligned access.
//
// Just like in the unaligned case, memcpy() is needed to avoid
// strict aliasing violations. However, on archs that don't support
// unaligned access the compiler cannot know that the pointers given
// to memcpy() are aligned which results in slow code. As of C11 there is
// no standard way to tell the compiler that we know that the address is
// aligned but some compilers have language extensions to do that. With
// such language extensions the memcpy() method gives excellent results.
//
// What to do on a strict-align system when no known language extentensions
// are available? Falling back to byte-by-byte access would be safe but ruin
// optimizations that have been made specifically with aligned access in mind.
// As a compromise, aligned reads will fall back to non-compliant type punning
// but aligned writes will be byte-by-byte, that is, fast reads are preferred
// over fast writes. This obviously isn't great but hopefully it's a working
// compromise for now.

/**
* \file api/lzma.h
* \brief The public API of liblzma data compression library
*
* liblzma is a public domain general-purpose data compression library with
* a zlib-like API. The native file format is .xz, but also the old .lzma
* format and raw (no headers) streams are supported. Multiple compression
* algorithms (filters) are supported. Currently LZMA2 is the primary filter.
*
* liblzma is part of XZ Utils <http://tukaani.org/xz/>. XZ Utils includes
* a gzip-like command line tool named xz and some other tools. XZ Utils
* is developed and maintained by Lasse Collin.
*
* Major parts of liblzma are based on Igor Pavlov's public domain LZMA SDK
* <http://7-zip.org/sdk.html>.
*
* The SHA-256 implementation is based on the public domain code found from
* 7-Zip <http://7-zip.org/>, which has a modified version of the public
* domain SHA-256 code found from Crypto++ <http://www.cryptopp.com/>.
* The SHA-256 code in Crypto++ was written by Kevin Springle and Wei Dai.

/*****************************
* Required standard headers *
*****************************/
/*
* liblzma API headers need some standard types and macros. To allow
* including lzma.h without requiring the application to include other
* headers first, lzma.h includes the required standard headers unless
* they already seem to be included already or if LZMA_MANUAL_HEADERS
* has been defined.
*
* Here's what types and macros are needed and from which headers:
* - stddef.h: size_t, NULL
* - stdint.h: uint8_t, uint32_t, uint64_t, UINT32_C(n), uint64_C(n),
* UINT32_MAX, UINT64_MAX
*
* However, inttypes.h is a little more portable than stdint.h, although
* inttypes.h declares some unneeded things compared to plain stdint.h.
*
* The hacks below aren't perfect, specifically they assume that inttypes.h
* exists and that it typedefs at least uint8_t, uint32_t, and uint64_t,
* and that, in case of incomplete inttypes.h, unsigned int is 32-bit.
* If the application already takes care of setting up all the types and
* macros properly (for example by using gnulib's stdint.h or inttypes.h),
* we try to detect that the macros are already defined and don't include
* inttypes.h here again. However, you may define LZMA_MANUAL_HEADERS to
* force this file to never include any system headers.
*
* Some could argue that liblzma API should provide all the required types,
* for example lzma_uint64, LZMA_UINT64_C(n), and LZMA_UINT64_MAX. This was
* seen as an unnecessary mess, since most systems already provide all the
* necessary types and macros in the standard headers.
*
* Note that liblzma API still has lzma_bool, because using stdbool.h would
* break C89 and C++ programs on many systems. sizeof(bool) in C99 isn't
* necessarily the same as sizeof(bool) in C++.

*
* Typical usage:
*
* - After allocating lzma_stream (on stack or with malloc()), it must be
* initialized to LZMA_STREAM_INIT (see LZMA_STREAM_INIT for details).
*
* - Initialize a coder to the lzma_stream, for example by using
* lzma_easy_encoder() or lzma_auto_decoder(). Some notes:
* - In contrast to zlib, strm->next_in and strm->next_out are
* ignored by all initialization functions, thus it is safe
* to not initialize them yet.
* - The initialization functions always set strm->total_in and
* strm->total_out to zero.
* - If the initialization function fails, no memory is left allocated
* that would require freeing with lzma_end() even if some memory was
* associated with the lzma_stream structure when the initialization
* function was called.
*
* - Use lzma_code() to do the actual work.
*
* - Once the coding has been finished, the existing lzma_stream can be
* reused. It is OK to reuse lzma_stream with different initialization
* function without calling lzma_end() first. Old allocations are
* automatically freed.

* - Finally, use lzma_end() to free the allocated memory. lzma_end() never
* frees the lzma_stream structure itself.

/**
* \file lzma/vli.h
* \brief Variable-length integer handling
*
* In the .xz format, most integers are encoded in a variable-length
* representation, which is sometimes called little endian base-128 encoding.
* This saves space when smaller values are more likely than bigger values.
*
* The encoding scheme encodes seven bits to every byte, using minimum
* number of bytes required to represent the given value. Encodings that use
* non-minimum number of bytes are invalid, thus every integer has exactly
* one encoded representation. The maximum number of bits in a VLI is 63,
* thus the vli argument must be less than or equal to UINT64_MAX / 2. You
* should use LZMA_VLI_MAX for clarity.

* Speed-optimized CRC32 using slicing-by-eight algorithm
*
* This uses only i386 instructions, but it is optimized for i686 and later
* (including e.g. Pentium II/III/IV, Athlon XP, and Core 2). For i586
* (e.g. Pentium), slicing-by-four would be better, and even the C version
* of slicing-by-eight built with gcc -march=i586 tends to be a little bit
* better than this. Very few probably run this code on i586 or older x86
* so this shouldn't be a problem in practice.
*
* Authors: Igor Pavlov (original version)
* Lasse Collin (AT&T syntax, PIC support, better portability)
*
* This file has been put into the public domain.
* You can do whatever you want with this file.
*
* This code needs lzma_crc32_table, which can be created using the
* following C code:
