Reduce CPU consumption in conv_10 function, used to format "%d" by apr_*printf
This includes two changes to APR:
* new functions apr_itoa, apr_ltoa, and apr_off_t_toa
that provide itoa-type functionality based on pools
* Inline code in inet_ntop4 to replace sprintf for converting
binary IP addresses into dotted-decimal format
and two changes to Apache:
* use the apr_itoa functions in setting the content length,
in place of apr_psprintf
* use the apr_itoa functions to replace frequent uses of
'sprintf("%d",...)' in mod_log_config.
