Clarification of pronoun - I had to read that sentence a few times to be certain what "it" referred to.

Also:
- Make ap_cfg_getline() return APR_ENOSPC if a config line is too long.
- Add ap_pcfg_strerror() function to convert ap_cfg_getline's return value
  into a nice message.
- Adjust definition of ap_configfile_t accordingly.

Not bumping MMN because it has already been bumped today.

some of these were exposed to mods so the mmn is bumped, without
regard to whether any compiler will have to generate different
code

library binding rather that stubbing out proper registered functions

This functionality should probably be moved into core, but for now
it's a lot better than nothing. And it may even help me debug some
other config related code.

related state has to be re-initialized to the default values
at pre-config time, but that was handled inconsistently by
the MPMs, resulting in unexpected behavior when some of the
directives were removed across restart

move that necessary initialization from the MPMs to common 
code run from core's pre-config; MPMs that need to override
defaults can do so by running after core's pre-config (the 
NetWare MPM now does that)

the DEFAULT_MAX_REQUESTS_PER_CHILD compile setting wasn't useful
enough to keep

the simple MPM wasn't consistent in which of these directives
were respected and which weren't, and that hasn't changed
(see procmgr.max_requests_per_child vs. ap_max_requests_per_child)
