46ef4487d3 Remove generic_buffer_*() functions as needless. 
These functions were there so that we could abstract the differences
between evbuffer and buf_t.  But with the bufferevent removal, this
no longer serves a purpose.

4f1a04ff9c Replace nearly all XXX0vv comments with smarter ones 
So, back long ago, XXX012 meant, "before Tor 0.1.2 is released, we
had better revisit this comment and fix it!"

But we have a huge pile of such comments accumulated for a large
number of released versions!  Not cool.

So, here's what I tried to do:

  * 0.2.9 and 0.2.8 are retained, since those are not yet released.

  * XXX+ or XXX++ or XXX++++ or whatever means, "This one looks
    quite important!"

  * The others, after one-by-one examination, are downgraded to
    plain old XXX.  Which doesn't mean they aren't a problem -- just
    that they cannot possibly be a release-blocking problem.

6f331645c7 Remove mempools and buf freelists 
They have been off-by-default since 0.2.5 and nobody has complained. :)

Also remove the buf_shrink() function, which hasn't done anything
since we first stopped using contiguous memory to store buffers.

Closes ticket 14848.

d87d4183ee Allow IPv4 and IPv6 addresses in SOCKS5 FQDN requests. 
Supposedly there are a decent number of applications that "support"
IPv6 and SOCKS5 using the FQDN address type.  While said applications
should be using the IPv6 address type, allow the connection if
SafeSocks is not set.

Bug not in any released version.

c8132aab92 Send back SOCKS5 errors for all of the address related failures. 
Cases that now send errors:
 * Malformed IP address (SOCKS5_GENERAL_ERROR)
 * CONNECT/RESOLVE request with IP, when SafeSocks is set
   (SOCKS5_NOT_ALLOWED)
 * RESOLVE_PTR request with FQDN (SOCKS5_ADDRESS_TYPE_NOT_SUPPORTED)
 * Malformed FQDN (SOCKS5_GENERAL_ERROR)
 * Unknown address type (SOCKS5_ADDRESS_TYPE_NOT_SUPPORTED)

Fixes bug 13314.

833d027778 Monotonize the OOM-killer data timers 
In a couple of places, to implement the OOM-circuit-killer defense
against sniper attacks, we have counters to remember the age of
cells or data chunks.  These timers were based on wall clock time,
which can move backwards, thus giving roll-over results for our age
calculation.  This commit creates a low-budget monotonic time, based
on ratcheting gettimeofday(), so that even in the event of a time
rollback, we don't do anything _really_ stupid.

A future version of Tor should update this function to do something
even less stupid here, like employ clock_gettime() or its kin.
