Internally, we still need this function, so we make it internal and
then add a new ERR_get_state() that simply calls the internal variant,
unless it's "removed" by configuration.

In ERR_add_error_vdata(), the size of err_data had 1 added to it in
some spots, which could lead to buffer overflow.
In ERR_vset_error(), ERR_MAX_DATA_SIZE was used instead of buf_size in
the BIO_vsnprintf() call, which would lead to a buffer overflow if
such a large buffer couldn't be allocated.

The new building block are ERR_new(), ERR_set_debug(),
ERR_set_error(), ERR_vset_error(), which allocate a new error record
and set the diverse data in them. They are designed in such a way
that it's reasonably easy to create macros that use all of them but
then rely completely on the function signature of ERR_set_error() or
ERR_vset_error().
