// Initialize a .xz decoder. The decoder supports a memory usage limit
// and a set of flags.
//
// The memory usage of the decompressor depends on the settings used
// to compress a .xz file. It can vary from less than a megabyte to
// a few gigabytes, but in practice (at least for now) it rarely
// exceeds 65 MiB because that's how much memory is required to
// decompress files created with "xz -9". Settings requiring more
// memory take extra effort to use and don't (at least for now)
// provide significantly better compression in most cases.
//
// Memory usage limit is useful if it is important that the
// decompressor won't consume gigabytes of memory. The need
// for limiting depends on the application. In this example,
// no memory usage limiting is used. This is done by setting
// the limit to UINT64_MAX.
//
// The .xz format allows concatenating compressed files as is:
//
// echo foo | xz > foobar.xz
// echo bar | xz >> foobar.xz
//
// When decompressing normal standalone .xz files, LZMA_CONCATENATED
// should always be used to support decompression of concatenated
// .xz files. If LZMA_CONCATENATED isn't used, the decoder will stop
// after the first .xz stream. This can be useful when .xz data has
// been embedded inside another file format.
//
// Flags other than LZMA_CONCATENATED are supported too, and can
// be combined with bitwise-or. See lzma/container.h
// (src/liblzma/api/lzma/container.h in the source package or e.g.
// /usr/include/lzma/container.h depending on the install prefix)
