If this does not break the Unix system somehow, I'll be amazed. This should get most of it out, apologies for any errors this may cause on non-Windows ends which I cannot test atm.
Fix function names prefix
Use Unicode version of GetFinalPathNameByHandle
Use EG(windows_version_info) instead of RtlGetVersion
Use the specified handle_id instead of STD_OUTPUT_HANDLE
Switch from stream name to stream resource
Allow running tests capturing only stdout and/or stderr
Add tests for stream_vt100_support function
Export Win32 console functions
Fix x64 build
Use zend_long instead of long long, use GetConsole instead of GetFinalPathNameByHandleW to check if a handle is a valid console stream
Always use zend_long on any platform
Use _get_osfhandle to determine the standard handle
Accept stream names
Raise warnings in case of invalid stream parameter
Return true if disabling VT100 support on a not-console/redirected stream or on old Windows versions
Remove php_win32_console_os_supports_vt100
Differentiate stdin vs stdout/stderr
Simplify setting flag
Allow avoid piping STDIN
Let stream_vt100_support accept only resources
Fix run-tests
Revert console flags in case of failure
Simplify logic of stream_vt100_support when setting the flag
Return true if succeeded, false otherwise
Drop support for STDIN
More comprehensive tests for stream_vt100_support
Remove old tests
Fix name of included file and use absolute paths
Enable ENABLE_VIRTUAL_TERMINAL_PROCESSING on Windows by default
Remove tests for stream_vt100_support
Split stream_vt100_support into stream_isatty+sapi_windows_vt100_support
Add tests for stream_isatty
Add tests for sapi_windows_vt100_support
Return null from stream_isatty is neither Windows nor Posix
Fallback to S_ISCHR if neither Windows nor Posix
Avoid defining argc since it's only used once
Better comment about php_win32_console_fileno_is_console
Use events instead of cNumberOfEvents
Do not restore previous console mode
We need to restore previous console mode on failing SetConsole calls only for STDIN
Don't configure STDOUT/STDERR on Windows with PHP_CLI_WIN32_NO_CONSOLE
