errorDepth -- set the error printing depth

errorDepth i -- sets the error depth to i, which should be a small integer, returning the old value.

During the backtrace after an error message, a position in interpreted code is displayed only if the value of reloaded was at least as large as the error depth is now. Typically, the error depth is set to 1 so that messages from code pre-interpreted and reloaded with loaddata will not appear in the backtrace.
