readcb fires before connect eventcb, so we enable it in readcb now. But
perhaps lp should behave like sslproxy and not enable readcb until after
connect eventcb.
Note that there is no problem with sslproxy, it's just lp.
The global opts strings in this new tmp struct are used while cloning
global opts into proxyspec opts. A var of this type is passed around as
a flag to indicate if these opts are global (if non-NULL), so should be
stored in that struct and used as such, or proxyspec specific (if NULL),
so should not be used as global. This var is temporary, hence freed
immediately after configuration is complete.
Also improve and clean up.
Add testproxy e2e tests for POP3 and SMTP protocol validation.
We have detected that POP3 and SMTP protocol validation was broken
thanks to these new testproxy e2e tests. This is yet another example why
e2e tests are important.
We don't need parent or child ids unless debugging. IDLE and EXPIRED
conn logs do not need to report ids either. Ids are useful only in
detailed debug logs.
Do not pass pxy_thr_print_children() or bufferevent_getfd() to MAX() or
util_max() macro functions as params, or else they are called twice.
Since MAX() macro call duplicates params, do not call it nested either,
or else we get very long macro expansions.

Also, bufferevent_getfd() returns -1 if no file descriptor is associated
with the bufferevent.
Free vars.
Finalize sqlite3 statements.
Close sqlite3 db.
Init memory.
Do not close fd -1.
Some of these may be harmless, but we fix them anyway. Now valgrind
reports 0 "lost" memory, but some "still reachable", both for sslproxy
and lp.
Enable dst r/w events before socket connect.
Improve verbose debug logs using common header fields to better identify
connections.
Create function macros for fine* debug logs.
