Update postfix package to 2.10.2.  Here is brief changes.

2.10.2

* TLS Interoperability workaround: turn on SHA-2 digests by force. This
  improves interoperability with clients and servers that deploy SHA-2 digests
  without the required support for TLSv1.2-style digest negotiation.

* TLS Performance workaround: the Postfix SMTP server TLS session cache had
  become ineffective because recent OpenSSL versions enable session tickets by
  default, resulting in a different ticket encryption key for each smtpd(8)
  process. The workaround turns off session tickets. Postfix 2.11 will enable
  session tickets properly.

* TLS Interoperability workaround: Debian Exim versions before 4.80-3 may fail
  to communicate with Postfix and possibly other MTAs, with the following Exim
  SMTP client error message:

	TLS error on connection to server-name [server-address]
	(gnutls_handshake): The Diffie-Hellman prime sent by the server is not
	acceptable (not long enough)

  See the RELEASE_NOTES file for a Postfix SMTP server configuration
  workaround.

* Bugfix (defect introduced: 1997): memory leak while forwarding mail with the
  local(8) delivery agent, in code that handles a cleanup(8) server error.


2.10.1

* Workaround: down-stream maintainers fail to install the new
  smtpd_relay_restrictions safety net, causing breakage that could have been
  avoided. We now hard-code the safety net instead.


2.10.0

* Separation of relay policy (with smtpd_relay_restrictions) from spam policy
  (with smtpd_{client, helo, sender, recipient}_restrictions), which makes
  accidental open relay configuration less likely. The default is backwards
  compatible.

* HAproxy load-balancer support for postscreen(8) and smtpd(8). The nginx
  proxy was already supported by Postfix 2.9 smtpd(8), using XCLIENT commands.

* Support for the TLSv1 and TLSv2 protocols, as well as support to turn them
  off if needed for inter-operability.

* Laptop-friendly configuration. By default, Postfix now uses UNIX-domain
  sockets instead of FIFOs, and thus avoids MTIME file system updates on an
  idle mail system.

* Revised postconf(1) command. The "-x" option expands $name in a parameter
  value (both main.cf and master.cf); the "-o name=value" option overrides a
  main.cf parameter setting; and postconf(1) now warns about a $name that has
  no name=value setting.

* Sendmail-style "socketmap" lookup tables.

Import py27-Kerberos-1.1 as security/py-Kerberos.

This Python package is a high-level wrapper for Kerberos (GSSAPI)
operations.  The goal is to avoid having to build a module that
wraps the entire Kerberos.framework, and instead offer a limited
set of functions that do what is needed for client/server Kerberos
authentication based on RFC 4559.
+ py-Kerberos
Added security/py-Kerberos version 1.1
Import py27-cffi-0.7.2 as devel/py-cffi.

Foreign Function Interface for Python calling C code. The aim of
this project is to provide a convenient and reliable way of calling
C code from Python. The interface is based on LuaJIT's FFI and
follows a few principles:

o The goal is to call C code from Python. You should be able to do
  so without learning a 3rd language: every alternative requires
  you to learn their own language (Cython, SWIG) or API (ctypes).
  So we tried to assume that you know Python and C and minimize
  the extra bits of API that you need to learn.
o Keep all the Python-related logic in Python so that you don't
  need to write much C code.
o Work either at the level of the ABI (Application Binary Interface)
  or the API (Application Programming Interface). Usually, C
  libraries have a specified C API but often not an ABI.
o We try to be complete. For now some C99 constructs are not
  supported, but all C89 should be, including macros.
o We attempt to support both PyPy and CPython, with a reasonable
  path for other Python implementations like IronPython and Jython.
o Note that this project is not about embedding executable C code
  in Python, unlike Weave. This is about calling existing C libraries
  from Python.

Added devel/py-cffi version 0.7.2
Import py27-cparser-2.10 as devel/py-cparser.

pycparser is a parser for the C language, written in pure Python.
It is a module designed to be easily integrated into applications
that need to parse C source code.
+ py-cparser
Added devel/py-cparser version 2.10
