bf80e2df3f Replace calls to time(NULL) that occur on the order of once per read, one per write, or once per cell with calls to a function that looks at a cached value of time. This is tricksy to benchmark, since it will only help on systems where time() is a syscall and syscalls are relatively slow.

New, slightly esoteric function, tor_malloc_roundup().  While tor_malloc(x) allocates x bytes, tor_malloc_roundup(&x) allocates the same size of chunk it would use to store x bytes, and sets x to the usable size of that chunk.

Improved skew reporting:  "You are 365 days in the duture" is more useful than "You are 525600 minutes in the future".  Also, when we get something that proves we are at least an hour in the past, tell the controller "CLOCK_SKEW MIN_SKEW=-3600" rather than just "CLOCK_SKEW"

Refactor write_chunks_to_file_impl: break out the "pick a temporary name if it makes sense, and open the right filename" logic and the "close the file and unlink or rename if necessary" logic.  This will let us write big files in a smarter way than "Build a big string" or "make a list of chunks", once we get around to using it.

6b716fdfb9 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.

652dde72f1 bugfix: chdir to your datadirectory at the *end* of the 
daemonize process, not the beginning. this was a problem
because the first time you run tor, if your datadir isn't
there, and you have runasdaemon set to 1, it will try to
chdir to it before it tries to create it. oops.

bbaa3c7792 Implement more control spec functionality 
- Mapaddress
- Postdescriptor
- GetInfo on descriptors

Required changes elsewhere:
- Keep the most recent running_routers_t in the routerlist_t. That way we
  can learn about new routers and remember whether we were last told that
  they were up or down.  Also enables more simplifications.
- Keep the signed descriptor inside routerinfo_t.  This makes
  descriptor_entry_t in dirservers.c unneeded.
- Rename AddressMap (the verb) to MapAddress. Keep AddressMap as a noun.
- Check addresses for plausibility before mapping them.
