disabled. Explicitly re-enable some that we want to use, namely:

* strcpy() -> __builtin_strcpy()
* strcmp() -> __builtin_strcmp()
* strlen() -> __builtin_strlen()
We might also consider some others for GCC 3.x.

Tidy up some memory copying cruft:
...
bcopy.S is no longer needed
memmove and memcpy were both stacking r0 and unstacking it to keep the return value, so push this down into _memcpy.
rename _memcpy.S to memcpy.S.
memmove.S is now just a placeholder otherwise the make system automagically adds a memmove.c file to libkern.
memmove is just another entry point for memcpy.

intended to be used by host tools which may use libsa routines (such
as loadfile()) which need to use explicit byte-ordering.

Make sure that each va_start has one and only one matching va_end,

If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).

When loading ELF, zero out:
...
The e_shstrndx field in the ELF header, since we don't load .shstrtab.
The sh_name field in each section header, for the same reason.
The sh_offset field for any section we don't load.
This means the kernel has some chance of knowing what it's being given. It
also means that the behaviour of old kernels with new loaders should be
deterministic (if not terribly useful: they still can't find the symbol
table).
