e718fb324b fix race conditions, tests and some invalid return values 
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()

72f13aeacb CreateProcess: add stdin/out/err redirection 
When launching a new process stdin/stdout/stderr can be redirected by
passing the corresponding HANDLEs in the passed lpStartupInfo structure.
This is required for example if a pipe should be used as stdin/stdout.

If set in lpStartupInfo the file descriptor of the passed handle is
now used. The test was updated accordingly.

68e8569110 winpr/synch: remove the dependency on winsock.h 
winsock.h pulls in a lot of defines and dependencies that are not
required and partially unwanted in winpr's core (for parts that are not
related to network). In order to get rid of this dependency and have an
independent defines for extended winpr functions the WINPR_FD_* defines
are used internally (and for exposed functions). Where required, like in
WSAEventSelect, the FD_* is mapped to WINPR_FD_*.

c84e90bf06 winpr: fix CreateProcess signal handler issues 
The calling thread of CreateProcess can be in any library and
can have arbitrary signal masks and handlers.

We now save the caller's mask and  block all signals before forking.
After fork:
- child resets the handlers and unblocks all signals.
- parent restores the caller's original signal mask.

582856d142 winpr/process: handle pids <= 0 
TerminateProcess shouldn't call kill if the PID is <=0 because this has
unwanted effects (and is not what TerminateProcess should do):

* with PID == 0 any process in the same process group gets the signal
  sent
* with PID == -1 *every* processes that the running users has
  permissions to gets the signal sent
* with PID < -1 the process within the same process group and -PID gets
  the signal send

For more details see kill(2).

44904ad5d2 Fixed a race condition at thread creation 
The thread structure was incorrectly updated after the thread
function was already running. This caused a race condition with
thread exiting. When the thread function returned before the structure
was correctly updated, the exit routine cleaned up the handle as
it was incorrectly marked not started.
