1621 5389d 04h fabio /shark/branches/xen/ Move all the low level libc related headers from the OSLib to libc/.

Move the headers used to define the libc interface exported by Shark from
the OSLib to libc/arch/$(ARCH) (remember, by now ARCH can be only x86,) and
change their users to reflect the movement. There are still a couple of
problems to solve, that are how to deal with the libc code used inside the
kernel, and how to handle things that are on the boundary, e.g., some type
definitions and so on. Btw this had to be started from somewhere.
 
1619 5389d 09h fabio /shark/branches/xen/ Move the OSLib libc/libm code into libc/arch.

Isolate the libc/libm code inside the OSLib and move it to libc/ with
the long term goal of isolating and cleaning up the interfaces between
the system components. The ARCH configuration variable will choose
the architecture Shark is being compiled for.

Now the architecture specific part of the libc is in libc/arch/$(ARCH),
but the include/makefile support is far from being generic enough.
 
1618 5389d 23h fabio /shark/branches/xen/ Started a new xen/ branch.

The plan is to support xen (without HVM) as an execution platform, and,
in the process, to decouple the generic kernel from the OSLib, trying to
make it easier to port Shark to new architectures.
