zstdmt.

/dev/null permissions were modified when using sudo rights.
This fixes this bug during decompression.
More importantly, this patch adds a test, triggered in TravisCI,
ensuring unaltered /dev/null permissions.
* Fix `ZSTD_FRAMEHEADERSIZE_PREFIX` and `ZSTD_FRAMEHEADERSIZE_MIN` to
take a `format` parameter, so it is impossible to get the wrong size.
* Fix the places that called `ZSTD_FRAMEHEADERSIZE_PREFIX` without
taking the format into account, which is now impossible by design.
* Call `ZSTD_frameHeaderSize_internal()` with `dctx->format`.
* The added tests catch both bugs in `ZSTD_decompressFrame()`.
Fixes#1813.
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.
