Nick Mathewson 0d75344b0e Switch to random allocation on circuitIDs. 
Fixes a possible root cause of 11553 by only making 64 attempts at
most to pick a circuitID.  Previously, we would test every possible
circuit ID until we found one or ran out.

This algorithm succeeds probabilistically. As the comment says:

  This potentially causes us to give up early if our circuit ID
  space is nearly full.  If we have N circuit IDs in use, then we
  will reject a new circuit with probability (N / max_range) ^
  MAX_CIRCID_ATTEMPTS.  This means that in practice, a few percent
  of our circuit ID capacity will go unused.

  The alternative here, though, is to do a linear search over the
  whole circuit ID space every time we extend a circuit, which is
  not so great either.

This makes new vs old clients distinguishable, so we should try to
batch it with other patches that do that, like 11438.

README 

Tor protects your privacy on the internet by hiding the connection
between your Internet address and the services you use. We believe Tor
is reasonably secure, but please ensure you read the instructions and
configure it properly.

To build Tor from source:
        ./configure && make && make install
