overhaul of the thread support. Many things are now probably broken,
but at least with --tool=none, simple and not-so-simple threaded and
non-thread programs work.

- move LDT stuff out of core, into x86-linux specific stuff. Some of it
(VG_(do_useseg)()?) may be really x86-specific, rather than
x86/linux-specific, but that can be fixed later if it's really shared with
another OS.

- added x86-linux/core_platform.h
- factored out getting/setting of system call arguments, put it in
platform-specific part.

- create coregrind/x86-linux/ directory.
- move vg_unistd.h into x86-linux/, because it's platform-dependent. Also
rename it as vki_unistd.h to make clear it's a kernel interface thing.
