37d16c3cc7 Reserve enough space for rend_service_port_config_t 
In #14803, Damian noticed that his Tor sometimes segfaults. Roger noted
that his valgrind gave an invalid write of size one here. Whenever we
use FLEXIBLE_ARRAY_MEMBER, we have to make sure to actually malloc a
thing that's large enough.

Fixes bug #14803, not in any released version of Tor.

ac2f90ed00 Speed up hidden service bootstrap by reducing the initial post delay 
Drop the MIN_REND_INITIAL_POST_DELAY on a testing network to 5 seconds,
but keep the default at 30 seconds.

Reduces the hidden service bootstrap to 25 seconds from around 45 seconds.
Change the default src/test/test-network.sh delay to 25 seconds.

Closes ticket 13401.

74cd57517c New option "HiddenServiceAllowUnknownPorts" 
This allows hidden services to disable the anti-scanning feature
introduced in 0.2.6.2-alpha. With this option not set, a connection
to an unlisted port closes the circuit.  With this option set, only
a RELAY_DONE cell is sent.

Closes ticket #14084.

d31bcc4b23 Tidy status handling in rendservice.c 
We had some code to fix up the 'status' return value to -1 on error
if it wasn't set, but it was unreachable because our code was
correct.  Tweak this by initializing status to -1, and then only
setting it to 0 on success.  Also add a goto which was missing: its
absence was harmless.

d4ad254917 scan-build: bulletproof last-chance errormsg generation in rendservice.c 
If 'intro' is NULL in these functions, I'm pretty sure that the
error message must be set before we hit the end.  But scan-build
doesn't notice that, and is worried that we'll do a null-pointer
dereference in the last-chance errormsg generation.

d5cfbf96a2 Fix an uninitialized-read when parsing v3 introduction requests. 
Fortunately, later checks mean that uninitialized data can't get sent
to the network by this bug.  Unfortunately, reading uninitialized heap
*can* (in some cases, with some allocators) cause a crash if you get
unlucky and go off the end of a page.

Found by asn.  Bugfix on 0.2.4.1-alpha.
