sysif: fix inappropriate use of w_ convention.

Some functions in utf8.c have w_ prefixes. They are wide
character wrappers for functions that take multi-byte string
inputs.

The prefix is being inappropriately used in the names of a
few sysif functions that should be named _wrap.

* sysif.c (w_stat, w_lstat, w_fstat): Rename to do_stat,
do_lstat and do_fstat, respectively. These are callbacks
used with stat_impl.
(statp, statl, statf): Rename to stat_wrap, lstat_wrap and
fstat_wrap, following existing convention. Additionally,
stat_wrap becomes static since nothing outside this file
calls it.
(sysif_init): Follow renames of statp, statl and statf.

* sysif.h (statp): Declaration removed.
(statf): Renamed to fstat_wrap.

* parser.c (load_rcfile): Follow statf rename.
