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.
This patch however does not drop support for the BeOS compatible variant, Haiku, see Github PR #2697 which is currently a WiP
I intentionally left out some fragments for BeOS in the build system for that seems to be bundles
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.
The issue here is that winsock2 defines IP protocols as an enum,
so the preprocessor won't catch it. However all the items related
are available as of winxp (see ws2def.h), so it's safe just to have.

Use the new 'ZSTR' macros in the rest of the code.
Does not change anything to the generated code (thanks to compat macros) but cleaner.

Improve zend_string API
Add missing methods
I'm assuming that we want to have 64bit zend_longs on x32 here.
This fixes two typos in __x86_64__ macros and adds sign-extension
when assigning STREAM_COPY_ALL to zend_long.
