83fe07d3f2 Increase the length of the buffer in smartlist_string_num_isin().
This was harmless, since we only used this for checking for lists of
port values, but it's the principle of the thing.

Fixes 3175; bugfix on 0.1.0.1-rc

5d147d8527 Add a new flag to check_private_dir to make it _not_ change permissions
We'll need this for checking permissions on the directories that hold
control sockets: if somebody says "ControlSocket ~/foo", it would be
pretty rude to do a chmod 700 on their homedir.

59f9097d5c Hand-conversion and audit phase of memcmp transition
Here I looked at the results of the automated conversion and cleaned
them up as follows:

   If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
   changed it to a fast_memcmp or fast_memeq.

   Otherwise if there was a tor_memcmp that could turn into a
   tor_memneq or tor_memeq, I converted it.

This wants close attention.

[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

51e551d383 Detect and handle NULL returns from (gm/local)time_r
These functions can return NULL for otherwise-valid values of
time_t.  Notably, the glibc gmtime manpage says it can return NULL
if the year if greater than INT_MAX, and the windows MSDN gmtime
page says it can return NULL for negative time_t values.

Also, our formatting code is not guaranteed to correctly handle
years after 9999 CE.

This patch tries to correct this by detecting NULL values from
gmtime/localtime_r, and trying to clip them to a reasonable end of
the scale.  If they are in the middle of the scale, we call it a
downright error.

Arguably, it's a bug to get out-of-bounds dates like this to begin
with.  But we've had bugs of this kind in the past, and warning when
we see a bug is much kinder than doing a NULL-pointer dereference.

Boboper found this one too.

fe1137be6f Use SSL_*_ex_data instead of SSL_*_app_data
SSL_*_app_data uses ex_data index 0, which will be the first one allocated
by SSL_get_ex_new_index. Thus, if we ever started using the ex_data feature
for some other purpose, or a library linked to Tor ever started using
OpenSSL's ex_data feature, Tor would break in spectacular and mysterious
ways. Using the SSL_*_ex_data functions directly now may save us from
that particular form of breakage in the future.

But I would not be surprised if using OpenSSL's ex_data functions at all
(directly or not) comes back to bite us on our backends quite hard. The
specified behaviour of dup_func in the man page is stupid, and
crypto/ex_data.c is a horrific mess.
