6df01ab8ab sim: switch config.h usage to defs.h
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.

00330cd18a sim: callback: convert time interface to 64-bit
PR sim/27705
Rather than rely on time_t being the right size between the host &
target, have the interface always be 64-bit.  We can figure out if
we need to truncate when actually outputting it to the right target.

df68e12b3b sim: create header namespace
The gdb/callback.h & gdb/remote-sim.h headers have nothing to do with
gdb and are really definitions for the libsim API under the sim/ tree.
While gdb uses those headers as a client, it's not specific to it.  So
create a new sim/ namespace and move the headers there.

These vestiges of the 20 year old emulator are just getting in the way.
Punt all the dead code we either don't compile or don't use.
