Andrew Kelley debf307594 update all incremental tests to new std API 
they're still not passing on windows for some reason though

Andrew Kelley 77d2ad8c92 std: consolidate all instances of std.Io.Threaded into a singleton 
It's better to avoid references to this global variable, but, in the
cases where it's needed, such as in std.debug.print and collecting stack
traces, better to share the same instance.

Andrew Kelley e41342af83 std.Io.Threaded: reinstate fchmodat fallback 
Stephen Gregoratto (original author of the fallback) says:

I read through both libcs again to compare:

Musl:
- `stat` path. Check error.
- If path is a symlink, return `OPNOTSUPP`.
- `openat` path as `O_PATH|O_NOFOLLOW|O_CLOEXEC`. Return `OPNOTSUPP` if we got `ELOOP`.
- Build procfs filename.
- `stat` procfs file.
- If procfs file is a symlink, return `OPNOTSUPP`.
- close path fd.

Glibc:
- open path as `O_PATH|O_NOFOLLOW|O_CLOEXEC`.
- fstatat path fd.
- If path is a symlink, return `OPNOTSUPP`.
- Build procfs filename.
- chmod procfs filename. Return `OPNOTSUPP` if we got `ENOENT`.
- close path fd.

I prefer glibc since you open the path first, which avoids a possible
TOCTOU race.

Andrew Kelley 64de4a7371 std.Io.Threaded: remove handling of ECANCELED 
The only known situation in which this occurs is when using musl with
the undocumented extension PTHREAD_CANCEL_MASKED, causing the next
syscall to return ECANCELED.

However zig std lib does not use this mechanism, even when targeting
musl libc because it would require each async task to be on a fresh
pthread.

For the same reason, if third party code were to cause ECANCELED to be
returned from any of these syscalls, it would cause subsequent tasks to
be incorrectly canceled since they cannot be rearmed.

Thus, this Io implementation cannot handle this error code correctly,
expecting never to receive it.

Ryan Liptak 1136d36362 windows: Remove BadPathName from error set of GetFinalPathNameByHandle 
These validations are really only checking for kernel/mount manager
bugs, so an assert seems more appropriate.

Andrew Kelley 2f30b0f44d std.Progress.start: handle cancelation from isTty 
It's important not to swallow error.Canceled. We don't have recancel()
yet but that will be a way to "rearm" cancelation after handling it so
that it is not ignored.

Andrew Kelley f27bd87ade std.Io.Threaded: allow length-0 file writes 
At first I thought about keeping this as an assertion but I can see this
being useful if you already know how many bytes to read and you are
filling the end of the buffer.

This also more closely mirrors POSIX APIs.
