[STR New]

When fetching the error_log with LogLevel set to debug, (much) more data is
sent than is expected. The reason is that the mechanics of reading the file
and writing the data to the client is logged to the error_log, and this is
also sent back in the request. con->http.data_remaining ends up becoming
negative in this situation.

This patch avoids that behaviour by noticing when more data has been read
from a file to send than data_remaining indicates should be there, and
truncating the response.
