The test mode do no longer open a file `/dev/null` nor write anything to output.
This is supposed to be more efficient than writing to `/dev/null`,
and more universal too : the previous method was failing on Windows.
Compiling with clang-8 fails with the following errors:
largeNbDicts.c:562:37: error: implicit conversion turns floating-point
number into integer: 'const double' to 'U64' (aka 'unsigned long')
[-Werror,-Wfloat-conversion]

While fixing the detection of symbolic links on OpenBSD I noticed
inconsistent behaviour:
$ echo hello > hello
$ ln -s hello world
$ zstd hello world
Warning : world is a symbolic link, ignoring
hello :316.67% ( 6 => 19 bytes, hello.zst
$ ls *.zst
hello.zst
$ zstd world
world :316.67% ( 6 => 19 bytes, world.zst)
$ ls *.zst
hello.zst world.zst
The `--no-progress` flag disables zstd's progress bars, but leaves
the summary.
I've added simple tests to `playTests.sh` to make sure the parsing
works.
For OSX and Linux, add a signal handler to SIGABRT, SGIFPE, SIGILL,
SIGSEGV, and SIGBUS. When the program terminates unexpectedly the
handler will print the current stack to the terminal to help determine
the location of the failure.
On OSX the output will look like:
```
Stack trace:
4 zstd 0x000000010927ed96 main + 16886
5 libdyld.dylib 0x00007fff767d1015 start + 1
6 ??? 0x0000000000000001 0x0 + 1
```
On Linux the output will look like:
```
Stack trace:
./zstd() [0x4b8e1b]
./zstd() [0x4b928a]
./zstd() [0x403dc2]
/lib64/libc.so.6(__libc_start_main+0xf5) [0x7f5e0fbb0445]
./zstd() [0x405754]
```
As is, the code does not function on WIN32.
