client asks us to resolve (not connect to) an address, and we have a
cached answer, give them the cached answer.  Previously, we would give
them no answer at all.

 Make exitlist only output each result line once.

 Instead of just checking known-invalid addresses for DNS hijacking, we
 now check randomly generated addresses, and if too many of them map to
 the same IP, we assume that IP is the destination of a DNS hijack
 attempt.
 
 A little bird tells me that some DNS hijackers think that declining to
 give an A record for RFC2606 addresses (like .invalid and .example)
 makes them more standards compliant.  Standardswise, this is like an
 illicit brothel making sure that nobody has pulled the tags off the
 mattresss, but that doesn't get us out of working around it.
 


svn:r8465

 Specify and implement SOCKS5 interface for reverse hostname lookup.


svn:r8451

 Allow resolve requests to non-exits when they are specifically requested (via resolve foo.bar.exit).


svn:r8446

 Consider non-exit servers unsuitable for RESOLVE commands.


svn:r8442

 Resolve bug 330: detect ISPs that want to hijack failing DNS requests and basically domain-squat the entire internet.


svn:r8440

 Rename and document SearchDomains and ResolvConf options; warn if ServerDNSResolvConfFile is given but eventdns isnt enabled.


svn:r8439

 Fix a bug: Remember, each call to escaped() replaces the value returned from the last call to escaped().


svn:r8438

 Implement server-side reverse DNS using eventdns.  Add an option to routerdescs so we can tell which servers have eventdns enabled.

NEEDS REVIEW. Act on previous comment, and handle named servers differently: now, we allow multiple servers with the same name in the routerlist even if that name is reserved, but we check whether names are reserved when we try to look up routers by nickname. This is a minor security fix.  This makes router_add_to_routerlist O(1). This is a backport candidate.

svn:r8433

Stop searching routerlist for routers with the same identity as other routers (on router insert): we already have a map for that.  (We need to add an index field to routerinfo_t so we can figure out which point in the routerlist to replace.)  Also, add a comment to routerlist.c; arma, please advise?

svn:r8432

Malloc and friends are critical-path: Thus, add an it-wont-happen branch prediction for NULL returns, and skip the malloc(0) check on platforms where malloc(0) returns a pointer.

svn:r8431

Switch routerlist.c to using memcmp on digests rather than crypto_pk_cmp_keys(); speed up find_whitespace a lot (8x for me) by using a switch statement.  This should speed parsing a lot of routers at once by a lot.

log messages into it. no use learning that it's broken without
being able to learn what is broken too.
