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.
These vars are used while configuring proxyspecs, and freed right after
they are used. So they should not be in proxyspec struct.
Refactor accordingly.
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.
This is necessary to uniquely identify child conns. The src fd of child
conns was possibly not unique. We use this id in debug logs only.
Also relocate the update code related with this id.
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.
We don't need a privsep call to open a socket for child listener,
because listener port of child conns are assigned by the system, hence
are from non-privileged range above 1024.
So the open privsep socket is used only to update user atime now.
We have carried almost all conn init tasks from thrmgr to conn handling
thread. So we immediately add the conn to the conn list of its thr,
which renders both pending ssl conns list and in_thr_conns flag useless.
