This adds an asm/asm-prototypes.h header for ARM to fix the
broken symbol versioning for symbols exported from assembler
files.
In addition to the header, we have to do these other small
changes:
- move the 'extern' declarations out of memset_io/memcpy_io
to make them visible to the symbol version generator
- move the exports from bitops.h to {change,clear,set,...}bit.S
- move the exports from csumpartialgeneric.S into the files
including it
I couldn't find the correct prototypes for the compiler builtins,
so I went with the fake 'void f(void)' prototypes that we had
before.
