Well, for all I know we don't declare new error codes all
the time, and try to reuse suitable ones wherever possible.

I remember Hyrum once renamed some SVN_ERR_WC_... error code to
a more generic name and reused it outside libsvn_wc, but subsequently
renamed the error code to SVN_ERR_WC_... again for some reason
(but kept using it).

And I found use of SVN_ERR_RA_DAV_INVALID_CONFIG_VALUE outside
of libsvn_ra_dav so I thought it might be the correct thing to use it.

Ultimately many of our error number names are bound to some
subsystem for no good reason. I think we should identify the
inherently generic ones and put them in their own category,
but current practice seems to be to simply reuse error codes
wherever we can...
