OSProcessPlugin 4.5.1

Use an alternate signal stack to avoid consuming native stack space. This prevents stack usage problems when running on Cog (stack depth exceeded when a signal is being handled). Adapted from VMConstruction-Plugins-OSProcessPlugin.oscog-eem.38 with the following changes:

- Always use sigaltstack if the platform supports it (i.e. do not test for Cog).
- If SQ_ONSTACK is not defined, then assume the platform cannot support signalstack and use the default stack. Use macros to define away unsupportable code.
- Fix some type declarations to address int/pointer comparison
- Use #isDefined:inSmalltalk:comment:ifTrue:ifFalse:
