Refactored some platform dependent code into a new library, 

lib/arch.  This should make porting easier.  Will probably
continue to refactor a little more, moving platform dependent
event handling stuff into lib/platform.

Inheriting implementation from multiple classes can have unpleasant
consequences in C++ due to it's limited capabilities. Classes can
inherit from any number of interface classes. An interface class
provides only pure virtual methods.
Synergy breaks this rule in two places. First is that IInterface
implements the virtual destructor. However, it's just an empty
method so it doesn't really count. Second is MXErrno which provides
implementation for exceptions that use the global errno variable.

Portability
-----------
FIXME -- information about porting to new platforms
Porting synergy to a new platform requires the following steps:
- Setting up the build
- Adjusting lib/common/common.h
- Implementing lib/arch
- Implementing lib/platform
- Implementing primary and secondary screens for the platform
- Tweaking synergyc and synergys
Setting up the build:
The first phase is simply to create the files necessary to build the
other files. On Unix, synergy uses autoconf/automake which produces
a `configure' script that generates makefiles. On Windows, synergy
uses Visual C++ workspace and project files. If you're porting to
another Unix variant, you may need to adjust `configure.in',
`acinclude.m4', and Unix flavor dependent code in lib/arch.
Adjusting lib/common/common.h:
The lib/common/common.h header file is included directly or indirectly
by every other file. It prepares some platform dependent macros for
integer sizes and defines a macro for conveniently testing which
platform we're building on. That macro is named *_LIKE (e.g. UNIX_LIKE)
and has the value `1'. Exactly one *_LIKE macro must be defined by
common.h.
Implementing lib/arch:
Most platform dependent code lives in lib/arch. There are several
interface classes there and they must all be implemented for each
platform. See the interface header files for more information.
Implementing lib/platform:
Most of the remaining platform dependent code lives in lib/platform.
The code there implements platform dependent window, clipboard, and
screen saver handling. The following interfaces must be implemented:
