If we have a debian/micro-revision.i, replace the one in src/or
with our copy so that this will be the revision that ends up in
the binary. This is an informational only version string, but
it'd be kinda nice if it was (more) accurate nonetheless.
Of course this won't help if people manually patch around but
it's still preferable to claiming we are exactly upstream's source.
If we are building directly out of a git tree, update
debian/micro-revision.i in the clean target.
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.
