- Added a global var WErrorCode similar to errno or RErrorCode.

- New function wsyserrorwithcode(), like wsyserror() for prints the message
  for the specified error code, instead of errno. This is for cases where
  you can't call wsyserror() immediately after the error, but save errno
  code for a later use.
