fflush: correct buffer handling in __sflush
This fixes CVE-2014-8611 correctly.
The commit that purported to fix CVE-2014-8611 (805288c2f062) only hid it behind another bug. Two later commits, 86a16ada1ea6 and 44cf1e5eb470, attempted to address this new bug but mostly just confused the issue. This commit rolls back the three previous changes and fixes CVE-2014-8611 correctly.
The key to understanding the bug (and the fix) is that `_w` has different meanings for different stream modes. If the stream is unbuffered, it is always zero. If the stream is fully buffered, it is the amount of space remaining in the buffer (equal to the buffer size when the buffer is empty and zero when the buffer is full). If the stream is line-buffered, it is a negative number reflecting the amount of data in the buffer (zero when the buffer is empty and negative buffer size when the buffer is full).
At the heart of `fflush()`, we call the stream's write function in a loop, where `t` represents the return value from the last call and `n` the amount of data that remains to be written. When the write function fails, we need to move the unwritten data to the top of the buffer (unless nothing was written) and adjust `_p` (which points to the next free location in the buffer) and `_w` accordingly. These variables have already been set to the values they should have after a successful flush, so instead of adjusting them down to reflect what was written, we're adjusting them up to reflect what remains.
The bug was that while `_p` was always adjusted, we only adjusted `_w` if the stream was fully buffered. The fix is to also adjust `_w` for line-buffered streams. Everything else is just noise.

General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.
