b42ff6545a Use random bytes as our certificate serial numbers. 
Instead of using time(NULL) in our certificate serial numbers, use
eight random bytes as suggested in proposal 179.

055d6c01ff Write dynamic DH parameters to a file. 
Instead of only writing the dynamic DH prime modulus to a file, write
the whole DH parameters set for forward compatibility. At the moment
we only accept '2' as the group generator.

The DH parameters gets stored in base64-ed DER format to the
'dynamic_dh_params' file.

f28014bf1a Introduce write_bytes_to_new_file(). 
Introduce write_bytes_to_new_file(), a function which writes bytes to
a file only if that file did not exist.

7920ea55b8 Refactor tor_event_base_once to do what we actually want 
This version avoids the timeout system entirely, gives a nicer
interface, and lets us manage allocation explicitly.

d6c18c5804 Make process_handle_t private and fix some unit tests 
Let's *not* expose more cross-platform-compatibility structures, or
expect code to use them right.

Also, don't fclose() stdout_handle and stdin_handle until we do
tor_process_handle_destroy, or we risk a double-fclose.

e3cee8bc2e Simply initialize TLS context if DynamicDHGroups change. 
We used to do init_keys() if DynamicDHGroups changed after a HUP, so
that the dynamic DH modulus was stored on the disk. Since we are now
doing dynamic DH modulus storing in crypto.c, we can simply initialize
the TLS context and be good with it.

Introduce a new function router_initialize_tls_context() which
initializes the TLS context and use it appropriately.

we know.

9814019a54 Use openssl's counter mode implementation when we have 1.0.0 or later 
This shaves about 7% off our per-cell AES crypto time for me; the
effect for accelerated AES crypto should be even more, since the AES
calculation itself will make an even smaller portion of the
counter-mode performance.

(We don't want to do this for pre-1.0.0 OpenSSL, since our AES_CTR
implementation was actually faster than OpenSSL's there, by about
10%.)

Fixes issue #4526.
