Do a sweep and remove most WARNS=6 settings

2020-10-01T01:10:51Z

Repeating the default WARNS here makes it slightly more difficult to experiment with default WARNS changes, e.g. if we did something absolutely bananas and introduced a WARNS=7 and wanted to try lifting the default to that. Drop most of them; there is one in the blake2 kernel module, but I suspect it should be dropped -- the default WARNS in the rest of the build doesn't currently apply to kernel modules, and I haven't put too much thought into whether it makes sense to make it so.

Avoid hard-coding pipe buffer sizes in the pipe and fifo kqueue tests.

FreeBSD's mkstemp sets the temporary file's permissions to 600, and has ever since mkstemp was added in 1987. Coverity's warning is still relevant for portable programs since OpenGroup does not require that behavior, and POSIX didn't until 2008. But none of these programs are portable.

Fix Coverity warnings about mkstemp in tests

2018-08-16T21:36:19Z

umask(2) should always be used prior to mkstemp(3) so the temporary file won't be created with insecure permissions. Reported by: Coverity CID: 1331605 1347173 1375366 1339800 1331604 1296056 1296060 CID: 1296057 1296062 MFC after: 2 weeks
