Remove the incorrect register shuffle - we pass SYS___syscall as the
syscall number in v0 and pass all the original __syscall() args in their
original slots/regs.

Sync with HEAD

Rename "syscall" to "_syscall" and provide "syscall" as a weak alias.

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Since N32/N64 pass the first 8 arguments in registers, we can load all
the arguments into those registers before invoking the syscall having
the kernel syscall handler from having to do that.

Another bare minimum __syscall.
