replaced declaration of EA from u32 to unsigned long - this beast is
used only to cast it to (userland) pointer and proper integer type for
that is unsigned long.

On ppc, we emulate instructions that cause alignment exceptions. If we are
single-stepping an instruction and it causes an alignment exception, we
will currently do the next instruction as well before taking the
single-step exception. This patch fixes that, so we take the single-step
exception after emulating the instruction.

If we should happen to get an altivec assist exception while executing in
the kernel, we will currently try to handle it and fail, and end up oopsing
with (apparently) a segfault. (An altivec assist exception occurs for
floating-point altivec instructions with denormalized inputs or outputs if
the altivec unit is in java mode.)
This patch checks explicitly if we are in user mode and prints a useful
message if not.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
