Commit 80f722e97cf7 ("Cygwin: opendir(3): move ENOTDIR check into main

assertion that path_conv::check() already calls exists() and sets

on a fhandler_virtual object created for just this code snippet.  The
side effect of this is that the fileid member in the calling
fhandler_virtual object is not set after path_conv::check().

Move the fhandler_virtual::fileid member to path_conv::_virt_fileid
and create matching path_conv::virt_fileid() and fhandler_virtual::fileid()
methods.

Let path_conv::check() propagate the fileid set in the local

Cygwin: Do not show Error dialogs by default

...in a non-Cygwin child process.  Backported from MSYS2.
Downstream commit message follows.

In https://github.com/msys2/msys2-runtime/pull/18, we discussed a change
that would allow default Windows error handling of spawned processes to
kick in (such as registered JIT debuggers). We even agreed that it would
make sense to hide this functionality behind a flag, `winjitdebug`.

However, when this got upstreamed as 21ec498d7f (cygwin: use
CREATE_DEFAULT_ERROR_MODE in spawn, 2020-12-09), that flag was deemed
unnecessary.

But it would appear that it _is_ necessary: As reported in
https://github.com/msys2/MSYS2-packages/pull/2414#issuecomment-810841296
this new behavior is pretty disruptive e.g. in CI scenarios.

So let's introduce that `winjitdebug` flag (settable via the environment
variable `MSYS`) at long last.
