Conrad Meyer 852c303b61 copystr(9): Move to deprecate (attempt #2)
This reapplies logical r360944 and r360946 (reverting r360955), with fixed
copystr() stand-in replacement macro.  Eventually the goal is to convert
consumers and kill the macro, but for a first step it helps if the macro is
correct.

Prior commit message:

Unlike the other copy*() functions, it does not serve to copy from one
address space to another or protect against potential faults.  It's just
an older incarnation of the now-more-common strlcpy().

Add a coccinelle script to tools/ which can be used to mechanically
convert existing instances where replacement with strlcpy is trivial.
In the two cases which matched, fuse_vfsops.c and union_vfsops.c, the
code was further refactored manually to simplify.

Replace the declaration of copystr() in systm.h with a small macro
wrapper around strlcpy (with correction from brooks@ -- thanks).

Remove N redundant MI implementations of copystr.  For MIPS, this
entailed inlining the assembler copystr into the only consumer,
copyinstr, and making the latter a leaf function.
