Fix decoding of LZMA2 streams having no uncompressed data.
No .xz encoder creates files with empty LZMA2 streams,
but such files would still be valid and decompressors
must accept them.
Note that empty .xz files are a different thing than
empty LZMA2 streams. This bug didn't affect typical .xz
files that had no uncompressed data.

Fix coding style for real.
I clearly wasn't fully awake with the commit ac313d.
Thanks to Andrew Morton.

Get rid of XZ_FUNC.
In Linux 2.6.31 (or so) and earlier, the initramfs
decompression had its own compiled copy of the
decompression code that got thrown away after the
kernel had booted. It required that all functions were
marked with __init when built for initramfs decompression.
Nowadays zlib and LZO have a wrapper that requires that
the respective decompressor code has been been enabled (=y)
in the kernel config. Only the wrapper is marked with
__init. This patch helps doing the same with the XZ
decompressor.

Reduce code size on x86 (32-bit and 64-bit).
The variables in structures in xz_dec_lzma2.c were reordered
so that the variables that the code references most are near
the beginning of the structure within 128 bytes. This allows
three bytes smaller instructions to access the variables, and
saves around 700-900 bytes in code size.

Add support for allocating the LZMA2 dictionary dynamically.
Previously the dictionary was preallocated at initialization
time, which is useful since the decoder cannot then later run
out of memory, but in several cases it is just an annoying
limitation.
It is now possible to enable only the needed operation mode(s)
at build time, which saves a few bytes in code size if only
one or two modes are actually needed. Bigger savings would be
possible especially in single-call mode, but I'll think about
that later.
This commit changes the API by adding the mode argument to
xz_dec_init(). A new return value (XZ_MEM_ERROR) was also added,
but it is used only in the new XZ_DYNALLOC operation mode.

Avoid integer division, since it's not necessarily available
in early boot code in the Linux kernel. Thanks to Alain Knaff
for pointing this out.
It's possible that the compiler already avoided divide
instructions, but since there wasn't much to change,
it was simplest to change the code to be sure.

Add XZ_EXTERN macro and use it to mark all functions with
external linkage. This is needed to support marking those
functions as static in some situations in the Linux kernel.
XZ_EXTERN may be used for dllimport/dllexport too on some
other operating systems.
