- Updated wait_for_multiple_objects_enhanced() to handle a no-event request while alterable.
- Simplified wait_for_any_event() to by taking advantage of no-event alterable request in wait_for_multiple_objects_enhanced().
- Updated wait_for_any_event() to use MAX_CHILDREN limit instead of MAXIMUM_WAIT_OBJECTS limit.
- Removed unnecessary ZeroMemory() call.
- Created distinct definition MAXIMUM_WAIT_OBJECTS_ENHANCED
and modified functions to use it.
- Upped w32_select() event limit.
- Modified wait_for_multiple_objects_enhanced() to allow for 0 millisecond wait.
- Added wait_for_multiple_objects_enhanced() function that can logically handle wait-any on many children (system resources permitting).
- Added unit tests for wait_for_multiple_objects_enhanced().
- Incorporated use of wait_for_multiple_objects_enhanced() into main signal handler.
- Upped max child processes to 500.
OpenSSh privilege separation model - http://www.citi.umich.edu/u/provos/ssh/privsep.html
Posix_spawn is implemented in POSIX adapter as an alternative to fork() that is heavily used in Privilege separation.
Additional state info is added to sshd to accommodate distinguishing the various modes (privileged monitor, unprivileged child, authenticated child).
Required service state (like config and host keys) is transmitted over pipes from monitor to child processes.
Changes to installation scripts and tests to accomodate new architectural changes

1.If there are no sufficient permissions to open a file then _wstat64() is returning file not present but it should return the accessed denied.Fixed this.
2.Code cleanup in the posix compat files to align with the openbsd coding standard.
