3b838abf97 ZSTD_CCtx_setParameter : value argument is now int

46d470c20c Fix feature detection with multiple -arch flags 
When multiple -arch flags are used, the compiler invokes itself once for
each architecture. Apparently, input on stdin is consumed by the
compilation of the first arch and is no longer available to the
compilation of the second arch, which results in a build failure and the
potentially incorrect determination that a feature is not available. So
write the feature detection source to a file instead of using stdin.

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)

b83d1e7714 removed some static const variables 
and replaced by traditional macro constants.

Unfortunately, C doesn't consider `static const` to mean "constant"

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.

f17c1df1ac backtrace support compiled with more conditions 
following #1356,
only enable backtrace compilation on linux+glibc.

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.

don't assume __linux__ means __GLIBC__ on BACKTRACES_ENABLE 
check for __GLIBC__ instead of __linux__ as musl libc doesn't provide
execinfo.h

fixes compilation on Alpine Linux and Void Linux musl arches.

efbc3e823d fixed paramgrill wrong assert() conditions 
and slightly refactored affected function.

Honestly, the formula calculating variance should get a second reviewing round,
it's not clear if it's correct.

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.
