Add missing documentation for some options introduced in 0.2.3.x

  o Minor bugfixes (documentation):

    - Add missing documentation for the MaxClientCircuitsPending,

      UseMicrodescriptors, UserspaceIOCPBuffers, and

      _UseFilteringSSLBufferevents options, all introduced during

      the 0.2.3.x series.

    and you're running on Windows, setting this option to 1 will tell Libevent

    not to use the Windows IOCP networking API.  (Default: 1)

**UserspaceIOCPBuffers** **0**|**1**::

    If IOCP is enabled (see DisableIOCP above), setting this option to 1

    will tell Tor to disable kernel-space TCP buffers, in order to avoid

    needless copy operations and try not to run out of non-paged RAM.

    This feature is experimental; don't use it yet unless you're eager to

    help tracking down bugs. (Default: 0)

**_UseFilteringSSLBufferevents** **0**|**1**::

    Tells Tor to do its SSL communication using a chain of

    bufferevents: one for SSL and one for networking.  This option has no

    effect if bufferevents are disabled (in which case it can't turn on), or

    if IOCP bufferevents are enabled (in which case it can't turn off).  This

    option is useful for debugging only; most users shouldn't touch it.

    (Default: 0)

**CountPrivateBandwidth** **0**|**1**::

    If this option is set, then Tor's rate-limiting applies not only to

    remote connections, but also to connections to private addresses like

    but never attach a new stream to a circuit that is too old. (Default: 10

    minutes)

**MaxClientCircuitsPending** __NUM__::

    Do not allow more than NUM circuits to be pending at a time for handling

    client streams. A circuit is pending if we have begun constructing it,

    but it has not yet been completely constructed.  (Default: 32)

**NodeFamily** __node__,__node__,__...__::

    The Tor servers, defined by their identity fingerprints or nicknames,

    constitute a "family" of similar or co-administered servers, so never use

    To enable this option the compile time flag --enable-tor2webmode must be

    specified. (Default: 0)

**UseMicrodescriptors** **0**|**1**|**auto**::

    Microdescriptors are a smaller version of the information that Tor needs

    in order to build its circuits.  Using microdescriptors makes Tor clients

    download less directory information, thus saving bandwidth.  Directory

    caches need to fetch regular descriptors and microdescriptors, so this

    option doesn't save any bandwidth for them.  If this option is set to

    "auto" (recommended) then it is on for all clients that do not set

    FetchUselessDescriptors. (Default: auto)
