Track the number of connection_t separately from the number of open sockets. It is already possible to have connections that do not count: resolving conns, for one. Once we move from socketpairs to linked conns, and once we do dns proxying, there will be lots of such connections.

Fix a bug in displaying memory pool usage. Also dump cell allocation, and track padded_cell_ts as they are allocated and freed, to make sure we are not leaking cells.
svn:r9992
Add code to shrink the cell memory pool by discarding empty chunks that have been empty for the last 60 seconds. Also, instead of having test.c duplicate declarations for exposed functions, put them inside #ifdef foo_PRIVATE blocks in the headers. This prevents bugs where test.c gets out of sync.

Make all LD_BUG log messsages get prefixed with "Bug: ". Remove manually-generated "Bug: "s from log-messages. (Apparently, we remembered to add them about 40% of the time.)

On mingw, use "%I64u" to printf/scanf 64-bit integers, instead of the usual GCC "%llu". This prevents a bug when saving 64-bit int configuration values on mingw; the high-order 32 bits would get truncated. If the value was then reloaded, disaster would occur. (Fixes bug 400 and maybe also bug 397.) Backport candidate.

try to make aes encryption of cells about 30-40% faster where applicable. offer not available for all architectures or all versions of openssl.

Another optimization suggested by Shark output: shave off >90% of uses of logv by cutting down on calls to log_debug when log actually debugging. This is showing up in some profiles bug not others, and might be as much as 2.5%.
svn:r9612
Apply patch from coderman: have posix subthreads mask out signals. This could prevent some kinds of crashes when subthreads try to handle SIGPIPEs and die in the attempt. Backport candidate.
svn:r9603
Move all struct-offset-manipulation macros into util.h, and use them consistently. Because there are days when "SUBTYPE_P(handle, subtype, _base)" is just easier to read and write than "(basetp*)(((handle) - STRUCT_OFFSET(subtype, _base))".

Node-picking fixes: Never warn when a down node is listed in a config option (bug 348); always warn when a node in a config option is unnamed. Also, when entrynodes is configured, then build the guard list as: (parts of EntryNodes that were guards before), (the rest of EntryNodes), (the rest of the old guards). This last point ensures that EntryNode users will get the EntryNodes they want with the minimum change to their guard list.
svn:r9574
Handle errors on opening cached-routers* more uniformly and sanely: log not-found errors at level INFO, and all other errors at level WARN. Needs testing on win32.
svn:r9569
Implement proposal 106: stop requiring clients to have certificates, and stop checking for nicknames in certificates. [See proposal 106 for rationale.] Also improve messages when checking TLS handshake, to re-resolve bug 382.
