Nop out the read of the FS register in EMX's syscall interface for now.
...
Eventually, we'll maybe need to set the FS register to be a proper TIB pointer,
but I'm mostly hoping that everything else was well-behaved enough to always
use DosGetInfoBlocks() instead. Yeah, right.

Bunch More Work, mostly cleanup and organization.
...
Wanted to do this now before it gets out of hand.
Ideally, this can be used for a Winelib-like option eventually, too, where you
don't load OS/2 binaries at all but rather compile and link your OS/2-based
source code against this API reimplementation.

Bunch More Work on getting an EMX-based "hello world" to run.
...
It looks like most of the remaining work for that is filling in dozens of
OS/2 APIs that EMX uses at startup just so we can get to our single
printf() call. :)

More fixup fixes. We're now into EMX crt0.s, calling missing doscalls APIs.

Don't load modules that are marked as non-loadable.

(Whatever that means in practice.)

Load all the object pages into memory before fixing them up.

Otherwise, we might fixup a page that isn't loaded yet!

Not there yet, but the framework is pretty close to what I want.

Don't map resource objects.
...
For one, they generally have a base address of 0x0, but also, we're probably
going to load/parse these into a hashtable somewhere in the loader
and use that for resource lookups instead of parsing LX binaries during
DosGetResource(), and that is more of a malloc() thing than an mmap() thing.

(I guess on i386, PROT_READ implies PROT_EXEC anyhow.)
