In preparation for converting to pt_regs syscall wrappers, convert our existing compat wrappers to C. This will allow the pt_regs wrappers to be automatically generated, and will allow for the compat register manipulation to be folded in with the pt_regs accesses. To avoid confusion with the upcoming pt_regs wrappers and existing compat wrappers provided by core code, the C wrappers are renamed to compat_sys_aarch32_<syscall>. With the assembly wrappers gone, we can get rid of entry32.S and the associated boilerplate. Note that these must call the ksys_* syscall entry points, as the usual sys_* entry points will be modified to take a single pt_regs pointer argument.
