Earlier this year we changed our own stderr variable to use the standard name `stderr` (to avoid bugs where someone is using `stderr` instead of the curl-tool specific variable). This solution needed to override the standard `stderr` symbol via the preprocessor. This in turn didn't play well with unity builds and caused curl tool to crash or stay silent due to an uninitialized stderr. This was a hard to find issue, fixed by manually breaking out one file from the unity sources. To avoid two these two tricks, this patch implements a different solution: Restore using our own local variable for our stderr output and leave `stderr` as-is. To avoid using `stderr` by mistake, add a `checksrc` rule (based on logic we already used in lib for `strerror`) that detects any `stderr` use in `src` and points to using our own variable instead: `tool_stderr`.
