Tor 0.0.7 is out

We've fixed a number of crash bugs from 0.0.6.2, as well as a security
issue. I recommend upgrading, but it's not necessary.
Improvements since 0.0.6.2:
o Fixes for crashes and other obnoxious bugs:
- Fix an epipe bug: sometimes when directory connections failed
to connect, we would give them a chance to flush before closing
- When we detached from a circuit because of resolvefailed, we
would immediately try the same circuit twice more, and then
give up on the resolve thinking we'd tried three different
- Limit the number of intro circuits we'll attempt to build for a
hidden service per 15-minute period.
- Check recommended-software string *early*, before actually parsing
the directory. Thus we can detect an obsolete version and exit,
even if the new directory format doesn't parse.
o Fixes for security bugs:
- Remember which nodes are dirservers when you startup, and if a
random OR enables his dirport, don't automatically assume he's
a trusted dirserver.
o Other bugfixes:
- Directory connections were asking the wrong poll socket to
start writing, and not asking themselves to start writing.
- When we detached from a circuit because we sent a begin but
didn't get a connected, we would use it again the first time;
but after that we would correctly switch to a different one.
- Stop warning when the first onion decrypt attempt fails; they
will sometimes legitimately fail now that we rotate keys.
- Override unaligned-access-ok check when $host_cpu is ia64 or
arm. Apparently they allow it but the kernel whines.
- Dirservers try to reconnect periodically too, in case connections
- Fix some memory leaks in directory servers.
- Allow backslash in Win32 filenames.
- Made Tor build complain-free on FreeBSD, hopefully without
breaking other BSD builds. We'll see.
- Check directory signatures based on name of signer, not on whom
we got the directory from. This will let us cache directories more
- Rotate dnsworkers and cpuworkers on SIGHUP, so they get new config
- Doxygen markup on all functions and global variables.
- Make directory functions update routerlist, not replace it. So
now directory disagreements are not so critical a problem.
- Remove the upper limit on number of descriptors in a dirserver's
directory (not that we were anywhere close).
- Allow multiple logfiles at different severity ranges.
- Allow *BindAddress to specify ":port" rather than setting *Port
separately. Allow multiple instances of each BindAddress config
option, so you can bind to multiple interfaces if you want.
- Allow multiple exit policy lines, which are processed in order.
Now we don't need that huge line with all the commas in it.
- Enable accept/reject policies on SOCKS connections, so you can bind
to 0.0.0.0 but still control who can use your OP.
- Updated the man page to reflect these features.
