Changes to directory request statistics:
- Rename GEOIP statistics to DIRREQ statistics, because they now include
more than only GeoIP-based statistics, whereas other statistics are
GeoIP-dependent, too.
- Rename output file from geoip-stats to dirreq-stats.
- Add new config option DirReqStatistics that is required to measure
directory request statistics.
- Clean up ChangeLog.
Also ensure that entry guards statistics have access to a local GeoIP
database.
This patch adds a new compat_libevent.[ch] set of files, and moves our
Libevent compatibility and utilitity functions there. We build them
into a separate .a so that nothing else in src/commmon depends on
Libevent (partially fixing bug 507).
Also, do not use our own built-in evdns copy when we have Libevent
2.0, whose evdns is finally good enough (thus fixing Bug 920).
Now, when you call tor --digests, it dumps the SHA1 digest of each
source file that Tor was built with. We support both 'sha1sum' and
'openssl sha1'. If the user is building from a tarball and they
haven't edited anything, they don't need any program that calculates
SHA1. If they _have_ modified a file but they don't have a program to
calculate SHA1, we try to build so we do not output digests.
GCC's interpretation of the C99 aliasing rules, to be charitable,
creates a dialect of C intended for a better programmers than I am
certain of my ability to be in all times. I just spent 2 hours
tracking down a platform-hyperspecific libevent bug that turned out to
be because of this, and darned if I ever want to do *that* again.
One of Linus's recent rants will give you a picture of why GCC's
behavior here can lead to fun surprises in your binaries:

are stored when the --enable-local-appdata option is configured. This
changes the Windows path from %APPDATA% to a host local
%USERPROFILE%\Local Settings\Application Data\ path (aka,
LOCAL_APPDATA).

Unfortunately, old Libevents don't _put_ a version in their headers, so
this can get a little tricky. Fortunately, the only binary-compatibility
issue we care about is the size of struct event. Even more fortunately,
Libevent 2.0 will let us keep binary compatiblity forever by letting us
decouple ourselves from the structs, if we like.

Oops. We had been telling people to use --with-ssl-dir, which had not worked since 0.2.0.1-alpha: --with-openssl-dir was the one that worked. Make them both work, document --with-openssl-dir, and mark --with-ssl-dir as obsolete. Found by "Dave".
