Loading ELF binaries based on the section table is totally wrong.  This
still leaves the other fat bug of referencing symbols in an executable
unfixed, so people better don't run strip on their binaries ...

As added bonus the new loader is also 23 lines shorter.

Replaces the deprecated __attribute_used__ with __used.  Also makes some
style adjustments to abide by the kernel coding conventions.

C0_status doesn't need to be initialized at this point anyway; the register
will be initialized later.

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

XTC can only be set if VPA is clear, which it may not be. There is
also the possibility of a back to back c0 register access hazard to
take care of.
