get_interface_address6() fails regardless of the allocator used,
wever logging to the original severity of 0 causes an assert
error only with the bsd allocator. weird.

Implement domain-selection for logging. Source is documented; needs documentation in manpage (maybe). For now, see doxygen comment on parse_log_severity_config in log.c
svn:r13875
Fix all remaining shorten-64-to-32 errors in src/common. Some were genuine problems. Many were compatibility errors with libraries (openssl, zlib) that like predate size_t. Partial backport candidate.
svn:r13665
Fix a bug that kept buf_find_string_offset from finding a string at the very end of the buffer. Add a unit test for this. Also, do not save a pointer to a chunk that might get reallocated by buf_pullup().
svn:r13635
Re-tune mempool parametes based on testing on peacetime: use smaller chuncks, free them a little more aggressively, and try very hard to concentrate allocations on fuller chunks. Also, lots of new documentation.
svn:r13484
Add a couple of (currently disabled) strategies for trying to avoid using too much ram in memory pools: prefer putting new cells in almost-full chunks, and be willing to free the last empty chunk if we have not needed it for a while. Also add better output to mp_pool_log_status to track how many mallocs a given memory pool strategy is saving us, so we can tune the mempool parameters.
svn:r13428
As planned, rename networkstatus_vote_t to networkstatus_t, now that v3 networkstatuses are working and standard and v2 networkstatuses are obsolete.
svn:r13383
Push the strdups used for parsing configuration lines into parse_line_from_string(). This will make it easier to parse more complex value formats, which in turn will help fix bug 557
svn:r13020
Fix bug 575: protect the list of logs with a mutex. I couldn't find any appreciable change in logging performance on osx, but ymmv. You can undef USE_LOG_MUTEX to see if stuff gets faster for you.
svn:r13019
Use reference-counting to avoid allocating a zillion little addr_policy_t objects. (This is an old patch that had been sitting on my hard drive for a while.)

Here, have some terribly clever new buffer code. It uses a mbuf-like strategy rather than a ring buffer strategy, so it should require far far less extra memory to hold any given amount of data. Also, it avoids access patterns like x=malloc(1024);x=realloc(x,1048576);x=realloc(x,1024);append_to_freelist(x) that might have been contributing to memory fragmentation. I've tested it out a little on peacetime, and it seems to work so far. If you want to benchmark it for speed, make sure to remove the #define PARANOIA; #define NOINLINE macros at the head of the module.

Change tor_addr_t to be a tagged union of in_addr and in6_addr, not of sockaddr_in and sockaddr_in6. It's hardly used in the main code as it is, but let's get it right before it gets popular.
svn:r12660
relay's public (external) IP address too, unless
ExitPolicyRejectPrivate is turned off. We do this because too
many relays are running nearby to services that trust them based
on network address.

oprofile was telling me that a fair bit of our time in openssl was spent in base64_decode, so replace base64_decode with an all-at-once fairly optimized implementation. For decoding keys and digests, it seems 3-3.5x faster than calling out to openssl. (Yes, I wrote it from scratch.)
