bd18095edc blindfix for Visual : minor casting issue 
should not happen since SIGIGN is provided by <signal.h>,
so it should work "ouf of the box"

00fc1ba8dd cli: add Ctrl-C support, requested by @mike155 in #854 
Now, pressing Ctrl-C during compression or decompression
will erase operation artefact (unfinished destination file)
before leaving execution.

8afcc80e07 decode more data before triggering error 
fixes #874 :
when a frame is not properly terminated by a "last block" signal,
zstd -d used to detect it immediately and error out.
This version will decode and flush the last block, and only then issue an error.

c233bdbaee Increase maximum window size 
* Maximum window size in 32-bit mode is 1GB, since allocations for 2GB fail
  on my Mac.
* Maximum window size in 64-bit mode is 2GB, since that is the largest
  power of 2 that works with the overflow prevention.
* Allow `--long=windowLog` to set the window log, along with
  `--zstd=wlog=#`. These options also set the window size during
  decompression, but don't override `--memory=#` if it is set.
* Present a helpful error message when the window size is too large during
  decompression.
* The long range matcher defaults to a hash log 7 less than the window log,
  which keeps it at 20 for window log 27.
* Keep the default long range matcher window size and the default maximum
  window size at 27 for the API and CLI.
* Add tests that use the maximum window size and hash size for compression
  and decompression.

360238733a Adds LZ4 support by default if LZ4 is available 
Simple makefile change + quick typename change

Test:

  make clean
  make
  # successfully produces binary without lz4 support

  make clean
  # with flags to pick up my lz4 build
  make MOREFLAGS="-L/home/felixh/prog/lz4/lib -I/home/felixh/prog/lz4/lib"
  # successfully produces binary with lz4 support

  echo "TEST TEST TEST THIS IS A TEST STRING PLEASE TEST THIS PLEASE OK THANK YOU" | \
    ./lz4/lz4 | \
    LD_LIBRARY_PATH=/home/felixh/prog/lz4/lib ./zstd/zstd -d
  # successfully prints TEST TEST TEST THIS IS A TEST STRING PLEASE TEST THIS PLEASE OK THANK YOU
