When configure tor with --enable-bufferevents and
--enable-static-libevent, libevent_openssl would still be linked
dynamically. Fix this and refactor src/or/Makefile.am along the way.
To turn this on, set UseMicrodescriptors to "1" (or "auto" if you
want it on-if-you're-a-client). It should go auto-by-default once
0.2.3.1-alpha is released.
Because of our node logic, directory caches will never use
microdescriptors when they have the right routerinfo available.
Previously we ensured that it would get called periodically by doing
it from inside the code that added microdescriptors. That won't work
though: it would interfere with our code that tried to read microdescs
from disk initially. Instead, we should consider rebuilding the cache
periodically, and on startup.
A v0 HS authority stores v0 HS descriptors in the same descriptor
cache that its HS client functionality uses. Thus, if the HS
authority operator clears its client HS descriptor cache, ALL v0
HS descriptors will be lost. That would be bad.
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.
Previously, it would remove every trackhostexits-derived mapping
*from* xyz.<exitname>.exit; it was supposed to remove every
trackhostexits-derived mapping *to* xyz.<exitname>.exit.
Bugfix on 0.2.0.20-rc: fixes an XXX020 added while staring at bug-1090
issues.

These were mostly releated to the routerinfo_t->node_t conversion.
