[PATCH] Replace svn_io_set_file_read_write_carefully

Any objections to the attached patch? Its a step toward supporting
Apache 2.2/APR 1.x on Win32.

Log:
Replace svn_io_set_file_read_write_carefully with
svn_io_set_file_read_write_perms which has been updated to work with
APR 1.x behavior on Win32.

It's behavior on unix style OS' is unchanged, but on Win32 it now just
forwards the calls to the appropriate svn_io_set_file_read_* functions.

Setting permissions on Win32 is unimplemented in APR, and Win32's
inherited ACL's do the right thing anyway on filesystems that support
permissions.
