Drop the sim-specific unsignedXX types and move to the standard uintXX_t
types that C11 provides.

The defs.h header will take care of including the various config.h
headers. For now, it's just config.h, but we'll add more when we
integrate gnulib in.
This header should be used instead of config.h, and should be the
first include in every .c file. We won't rely on the old behavior
where we expected files to include the port's sim-main.h which then
includes the common sim-basics.h which then includes config.h. We
have a ton of code that includes things before sim-main.h, and it
sometimes needs to be that way. Creating a dedicated header avoids
the ordering mess and implicit inclusion that shows up otherwise.

When compiling we get the following warnings:

Define and wire up unordered floating point comparison operations for cgen
targets. This patch depends on my posted cgen patches[0].
