Anatol Belski f3f6cd24e9 Modernize realpath and integrate quick variant into virtual_file_ex
The slower I/O as a traditional bottleneck on Windows which is
the target of this patch. The recursive path resolution, while being
an allround solution, is expensive when it comes to the common case.
Files with proper ACLs set can be resolved in one go by usage of specific
API. Those are available since Vista, so actually can be called old. Those
simpler api is used for the cases where no CWD_EXPAND is requested. For
the cases where ACLs are improper, the existing solution based on
FindFirstFile still does good job also partially providing quirks. Cases
involing reparse tags and other non local filesystems are also partially
server by new APIs.

The approach uses both APIs - the quick one for the common case still
integrating realpath cache, and the existing one as a fallback. The tests
show the I/O load drop on the realpath resolution part due to less
system calls for the sub part resolution of paths. In most case it is
justified, as the sub parts were otherwise cached or unused as well. The
realpath() implementation in ioutil is also closer to the POSIX.
