Since the current winpr implementation for overlapped operations is
incomplete and buggy, all affected functions will now fail if they are
called with a set FILE_FLAG_OVERLAPPED flag or a non-null pointer to
a OVERLAPPED structure.
winpr/nt:
- use proper one-time initialization on win32
- fix TestNtCreateFile
- fix broken/incomplete _RtlAnsiStringToUnicodeString
- unimplemented functions return appropriate error codes
winpr/pipe:
- improved TestPipeCreateNamedPipe
- rewrite the completely broken TestPipeCreateNamedPipeOverlapped test
rdtk:
- improve test and don't blindly return success
winpr/synch:
- fix race condition in TestSynchTimerQueue
winpr/ssspi:
- fix TestEnumerateSecurityPackages printf output
- fix TestQuerySecurityPackageInfo printf output
winpr/environment:
- fix GetEnvironmentStrings printf output
winpr/comm:
- unimplemented functions return appropriate error codes
winpr/io:
- unimplemented functions return appropriate error codes
winpr/thread:
- implement SwitchToThread() via sched_yield()
The used method for initalizing and registering the handle creators
had certain disadvantages like that it was necessary to have the creators
initialized before the first call to CreateFile. In case of comm it
wouldn't have been possible to open an comm port without calling any
other call related function first.
Now the handle creators are initialized the first time CreateFile is
called. This way it is also possible to ensure a certain order of the
handler invocations.
This commit also splits out the client side named pipe code from
the generic file handling (now called generic.c instead of file.c) and
uses the new handle creator infrastructure to register.
