Use correct stack size on OpenBSD

On OpenBSD, applications using webkit 2.0.1 get 

** Message: console message: undefined @0: RangeError: Maximum call
stack size exceeded.

on startup with javascript enabled.  It basically causes Javascript not to work.

In StackBounds.cpp, webkit says
// FIXME: remove this! - this code unsafely guesses at stack sizes!
#if OS(WINDOWS) || OS(SOLARIS) || OS(OPENBSD)

Well, on OpenBSD, we don't need to guess.  Attached is a patch that uses stack size returned from pthread_stackseg_np.  The makes things work just fine.  No errors and no crashes.  Been tested by multiple users.

Also, on OpenBSD, hppa/hppa64 grows its stack size up, so add a define to give the hppa archs a chance to work.
