Move last few conf items to FR_CONF_OFFSET

and fix resulting compiler warnings
Don't return OK for EAP-MSCHAPv2 success/fail

it breaks other things in the server, when we have

	eap {
		ok = return
	}

There is minimal additional cost to doing this
Remove one last check for zero
Track response_window to request->delay.  Addresses #645

We track the min_response_window for all home servers, and
then use that value when setting request->delay.  This lets us
deal more quickly with home servers which need sub-second timers
Set prefix to /32 if it wasn't set
Added per-client response_window.  Closes #645
Move prefix_ptr to a higher scope
trailing spaces aren't necessary
Fix Coverity #1216798 #1216797 #1216796 #1216795 #1216794
Reformatting and another enum
Fix scan error
More conversion to FR_CONF_OFFSET
More conversion to FR_CONF_OFFSET

and fix up the various dependent data types
More FR_CONF_OFFSET fixups

perl -0777 -p -i -e  's/PW_TYPE_([^,]+),\s+offsetof\(([^,]+),\s*([^,]+)\),\s*0,/FR_CONF_OFFSET(PW_TYPE_$1, $2, $3),/mg' src/main/connection.c
Break out IP parsing into fr_pton and fr_pton6. Any function which needs to parse IP addresses or IP prefixes in the server should be accommodated by these functions.
Fix all remaining config items to use FR_CONF_OFFSET

Add support to the conffile parser for parsing IPv4 addresses in octal and hex format

Add support to conffile parser for parsing prefix type config items

Standardise on using fr_ipaddr_t structures to represent IP addresses in the conffile
code, and other places.
Add FR_TIMEVAL_BOUND_CHECK

Add FR_TIMEVAL_BOUND_CHECK implementing bounding for struct
timeval values, similarly to FR_INTEGER_BOUND_CHECK. Use it in
home_server_add and client_parse to increase readability.
Rename min_response_window to init_delay

Rename main_config's "min_response_window" field to "init_delay", as it
better reflects the usage and because its value won't be related to any
response window in case they're all higher than 1/3 s, which is true
most of the time.
