Ensure that libsvn_ra_dav converts the encoding of Neon error messages to
UTF-8.

* libsvn_ra_dav/ra_dav.h, libsvn_ra_dav/util.c, libsvn_ra_dav/commit.c,
  libsvn_ra_dav/fetch.c (svn_ra_dav__convert_error): Added pool argument.
  Callers updated.
  Convert error message and hostname acquired from Neon to UTF-8.
