Fix compilation of utf8proc.c/h with Visual Studio 2015, which
cleans up a lot of standard system headers (and includes several new
headers).

Apr doesn't detect these headers yet, so we can't use its detection.
(These headers are really part of the compiler; not the SDK)

* libsvn_subr/utf8proc/utf8proc.h
  (defines): Use stdbool.h and stdint.h instead of local redefines that
    now conflict with those in other headers, such as those included by apr.
