Added the debug directory and the first debug tool

(sync_flush). These tools are not built unless the
user runs "make" in the debug directory.

Fix LZMA_SYNC_FLUSH handling in LZ and LZMA encoders.

That code is now almost completely in LZ coder, where
it can be shared with other LZ77-based algorithms in
future.

Set stdin and stdout to binary mode on Windows. This patch is

a forward port of b7b22fcb979a16d3a47c8001f058c9f7d4416068
from lzma-utils-legacy.git. I don't know if the new code base
builds on Windows, but this is a start.

This new set of tests compress and decompress several
test files with many different compression options.
This set of tests will be extended later.

Subblock decoder: Don't exit the main loop in decode_buffer()
...
too early if we hit End of Input while decoding a Subblock of
type Repeating Data. To keep the loop termination condition
elegant, the order of enumerations in coder->sequence were
changed.
To keep the case-labels in roughly the same order as the
enumerations in coder->sequence, large chunks of code was
moved around. This made the diff big and ugly compared to
the amount of the actual changes made.

Fix wrong too small size of argument unfiltered_max
...
in ia64_coder_init(). It triggered assert() in
simple_coder.c, and could have caused a buffer overflow.
This error was probably a copypaste mistake, since most
of the simple filters use unfiltered_max = 4.

Revised the fastpos code. It now uses the slightly faster
...
table-based version from LZMA SDK 4.57. This should be
fast on most systems.
A simpler and smaller alternative version is also provided.
On some CPUs this can be even a little faster than the
default table-based version (see comments in fastpos.h),
but on most systems the table-based code is faster.
