This shouldn't be a user-visible change: nobody has a 16 MB RSA
key that they're trying to use with Tor.
I'm doing this to fix CID 1439330 / ticket 27730, where coverity
complains (on 64-bit) that we are making a comparison that is never
true.
In hs_config.c, we do validate the permission of the hidden service directory
but we do not try to create it. So, in the event that the directory doesn't
exists, we end up in the loading key code path which checks for the
permission and possibly creates the directory. On failure, don't BUG() since
there is a perfectly valid use case for that function to fail.
Fixes#27335

This is harder than with OpenSSL, since OpenSSL counts the bytes on
its own and NSS doesn't. To fix this, we need to define a new
PRFileDesc layer that has its own byte-counting support.
Closes ticket 27289.
Before 0.3.3.1-alpha, we would exit() in this case immediately. But
now that we leave tor_main() more conventionally, we need to make
sure we restore things so as not to cause a double free.
Fixes bug 27708; bugfix on 0.3.3.1-alpha.
All node_get_all_orports() does is allocate and return a smartlist
with at most two tor_addr_port_t members that match ORPort's of
node configuration. This is harmful for memory efficiency, as it
allocates the same stuff every time it is called. However,
node_is_a_configured_bridge() does not need to call it, as it
already has all the information to check if there is configured
bridge for a given node.
The new code is arranged in a way that hopefully makes each succeeding
linear search through bridge_list less likely.
We determine that a cell was dropped by inspecting CIRC_BW fields. If we did
not update the delivered or overhead fields after processing the cell, the
cell was dropped/not processed.
Also emit CIRC_BW events for cases where we decide to close the circuit in
this function, so vanguards can print messages about dropped cells in those
cases, too.
