[PD-dev] error missing in Pd 0.52

[Dan Wilcox]

You missed the discussion because it took place in libpd-land: https://github.com/libpd/libpd/issues/336 <https://github.com/libpd/libpd/issues/336>

It was not a decision taken lightly, but it's necessary as Pd's previous "error()" could conflict with libc "error()". The replacement already existed for sometime, so changing calls to "error(...)" with "pd_error(0, ...)" should be equivalent and not break the external in old versions of Pd.
