d7e10a774a added constant ZSTD_WINDOWLOG_LIMIT_DEFAULT 
answering #1407.

Also : removed obsolete function ZSTD_setDStreamParameter()
which could only be used with one parameter (DStream_p_maxWindowSize).
Now replaced by ZSTD_DCtx_setWindowSize() (which exists since a few revisions)

f181799082 fix decodecorpus incorrect frame generation 
fix #1379
decodecorpus was generating one extraneous byte when `nbSeq==0`.
This is disallowed by the specification.

The reference decoder was just skipping the extraneous byte.
It is now stricter, and flag such situation as an error.

433059bbb2 fixed minor gcc warning 
gcc-8 on Linux doesn't like usage of strncat :
`warning: ‘strncat’ output truncated before terminating nul copying as many bytes from a string as its length`.

Not sure what was wrong, it might be a false positive,
but the logic is simple enough to replaced by a simple `memcpy()`,
thus avoiding the shenanigans of null-terminated strings.

following #1356,

Also, disable backtrace by default from "release" compilation,
so that less platforms get impacted by the new requirements.
Can be manually enabled/disabled using BACKTRACE=1/0.

549c19b42e portability macro flags updates, for Haiku 
some non-trivial changes to platform.h and util.h,
initially related to compilation for Haiku,
but I used this opportunity to make them cleaner
and add some documentation.

Noticed several tests that could be improved
(too harsh conditions, useless exception, etc.)
but I did not dare modifying too many tests just before release.

3ca6261223 fixed static analyzer warnings 
note : for some reason,
scan-build version on my laptop found problems within fastcover.c
that scan-build on travisCI does not flag.

They are, as usual, false positive :
the analyzer does not understand that a table (`offset`) is correctly filled before usage.

d98733b37e restored backtrace on failure 
for Linux and Mac OS-X.

Note : the backtraces fires up through a trap
before the sanitizer get a chance to report.
There are situations where the sanitizer report is actually preferable.

It might be good to consider a kind of build macro
which can disable backtrace
when sanitizer is enabled.

a06574fc97
Print a stack trace on unexpected term signal (e.g. SIGABRT) 
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.

Merge pull request #1290 from edenzik/ezik/1119-safe-strcpy-in-fileio 
Fixed unsafe string copy and concat in `fileio.c`.

78af534f82 Fixed unsafe string copy and concat in fileio.c. 
Per warnings from flawfinder: "Does not check for buffer overflows when
copying to destination [MS-banned] (CWE-120). Consider using snprintf,
strcpy_s, or strlcpy (warning: strncpy easily misused).".

Replaced called to strcpy and strcat in `fileio.c` to calls with a
specified size (`strncpy` and `strncat`).

Tested the changes on OSX, Linux, Windows.
On OSX + Linux, changes were tested with ASAN. The following flags were
used: 'check_initialization_order=1:strict_init_order=1:detect_odr_violation=1:detect_stack_use_after_return=1'

To reproduce warning:
./flawfinder.py ./programs/fileio.c

only works with multi-threading for the time being.
