[cp-patches] FYI: New Posix Layer

[Roman Kennke]

I committed the new Posix-Layer that implements a couple of portability
macros and functions for use in our native code. This is meant to
replace the generic layer at some point in the future (maybe 1-2 weeks
before the next release or so). For the time beeing Torsten hacked the
generic layer to redirect to the posix layer if the build-time flag
CP_NEW is set. (Maybe somebody more familiar with the build-machinery
could add a configure switch for this?). Setting this flag does:

- use functions instead of macros for syscalls on Posix-like platforms
(enabling easier debugging)
- shorten macro names

The mapping from the old macro names to the new ones is done in the
generic layer until we decide that the posix layer is nice as it is and
turn it on by default.
