Windows,JNI: graceful error-handling
CreateJunction and DeletePath are now more
resilient to errors:
- CreateJunction opens the junction path to check
its target requesting fewer rights and with
greater sharing permission. This way it can
check junction targets even if the junction name
is opened by another process with no sharing.
- DeletePath attempts to call FindFirstFileW if
GetFileAttributesW fails with
ERROR_ACCESS_DENIED. There's hardly any info
about this error mode online, except for a code
comment in the .NET CoreFX library. (See new
code comments in this commit.)
Also:
- Change the error codes for DeletePath.
- Wrap the DeletPath error codes in a struct for
better readability.
