Minor cleanups on hidden service usage patch from Karsten: tidy documentation; make free_all idempotent (and safe to call even if we have not yet initialized rephist); and stop using "l" as a variable name (it is too easy to confuse with "1").
svn:r10068
Initial version of patch from Karsten Loesing: Add an HSAuthorityRecordStats option to track statistics of overall hidden service usage without logging information that would be useful to an attacker.

The otherwise regrettable MIPSpro C compiler warns about values set but never used, and about mixing enums and ints; these are good warnings, and so should be fixed. This removes some dead code and some potential bugs. Thanks to pnx.

circuit_t into origin_circuit_t and or_circuit_t. I fixed some
segaults; there may be more. We still need to move more rendezvous
stuff into subtypes.
This is a trial run for splitting up connection_t; if the approach is
insane, please say so soon so we can do something smarter.
Also, this discards the old HALF_OPEN code, which nobody seems to
want.

1) Surround all constants by (parens), whether we'll be using them
in a denominator or not.
2) Express all time periods as products (24*60*60), not as multiplied-out
constants (86400).
3) Comments like "(60*60) /* one hour */" are as pointless as comments
like "c = a + b; /* set c to the sum of a and b */". Remove them.
4) All time periods should be #defined constants, not given inline.
5) All time periods should have doxygen comments.
6) All time periods, unless specified, are in seconds. It's not necessary
to say so.
To summarize, the old (lack of) style would allow:
#define FOO_RETRY_INTERVAL 60*60 /* one hour (seconds) */
next_try = now + 3600;
The new style is:
/** How often do we reattempt foo? */
#define FOO_RETRY_INTERVAL (60*60)
next_try = now + RETRY_INTERVAL;

we screwed up the formatting in wild and unpredictable ways.
fix it before it becomes convention to format logs in wild and
unpredictable ways.
still need to do src/common/ someday.

- Add a new extend_info_t datatype to hold information needed to
extend a circuit (addr,port,keyid,onion_key). Use it in cpath and
build_state. Make appropriate functions take or return it instead of
routerinfo_t or keyid.
- #if 0 needless check in circuit_get_by_edge_conn; if nobody triggers this
error in 0.1.0.10, nobody will trigger it.
- Implement new hidden service descriptor format, which contains "extend
info" for introduction points, along with protocol version list.
- Parse new format.
- Generate new format
- Cache old and new formats alongside each other.
- Directories serve "old" format if asked in old way, "newest available"
format if asked in new way.
- Use new format to find introduction points if possible; otherwise fall
back. Keep nickname lists and extendinfo lists in sync.
- Tests for new format.
- Implement new "v2" INTRODUCE cell format.
- Accept new format
- Use new format if we have a versioned service descriptor that says the
server accepts the new format.
- Add documentation for functions and data types.

until none are left, then we try to refetch the descriptor. If it's
the same one we had before, then close streams right then. Whenever
a new stream arrives, even if it's right after, optimistically try
refetching the descriptor, just in case.
