Subject: ics-openvpn as a submodule! beautiful

ics-openvpn is now officially on GitHub, and they track openssl and
openvpn as submodules, so it's easier to update everything. Just a git
submodule update --recursive.

I've also set up soft links to native modules from ics-openvpn in app,
so that we don't copy files in Gradle (which was causing problems with
the submodules .git* files, not being copied). That makes the repo
cleaner.

-# ====================================================================
-# [Re]written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL
-# project. The module is, however, dual licensed under OpenSSL and
-# CRYPTOGAMS licenses depending on where you obtain it. For further
-# details see http://www.openssl.org/~appro/cryptogams/.
-# ====================================================================
-
-# "[Re]written" was achieved in two major overhauls. In 2004 BODY_*
-# functions were re-implemented to address P4 performance issue [see
-# commentary below], and in 2006 the rest was rewritten in order to
-# gain freedom to liberate licensing terms.
-
-# January, September 2004.
-#
-# It was noted that Intel IA-32 C compiler generates code which
-# performs ~30% *faster* on P4 CPU than original *hand-coded*
-# SHA1 assembler implementation. To address this problem (and
-# prove that humans are still better than machines:-), the
-# original code was overhauled, which resulted in following
-# performance changes:
-#
-#		compared with original	compared with Intel cc
-#		assembler impl.		generated code
-# Pentium	-16%			+48%
-# PIII/AMD	+8%			+16%
-# P4		+85%(!)			+45%
-#
-# As you can see Pentium came out as looser:-( Yet I reckoned that
-# improvement on P4 outweights the loss and incorporate this
-# re-tuned code to 0.9.7 and later.
-# ----------------------------------------------------------------

-
-# August 2009.
-#
-# George Spelvin has tipped that F_40_59(b,c,d) can be rewritten as
-# '(c&d) + (b&(c^d))', which allows to accumulate partial results
-# and lighten "pressure" on scratch registers. This resulted in
-# >12% performance improvement on contemporary AMD cores (with no
-# degradation on other CPUs:-). Also, the code was revised to maximize
-# "distance" between instructions producing input to 'lea' instruction
-# and the 'lea' instruction itself, which is essential for Intel Atom
-# core and resulted in ~15% improvement.
-
-# October 2010.
-#
-# Add SSSE3, Supplemental[!] SSE3, implementation. The idea behind it
-# is to offload message schedule denoted by Wt in NIST specification,
-# or Xupdate in OpenSSL source, to SIMD unit. The idea is not novel,
-# and in SSE2 context was first explored by Dean Gaudet in 2004, see
-# http://arctic.org/~dean/crypto/sha1.html. Since then several things
-# have changed that made it interesting again:
-#
-# a) XMM units became faster and wider;
-# b) instruction set became more versatile;
-# c) an important observation was made by Max Locktykhin, which made
-#    it possible to reduce amount of instructions required to perform
-#    the operation in question, for further details see
-#    http://software.intel.com/en-us/articles/improving-the-performance-of-the-secure-hash-algorithm-1/.
-
-# April 2011.
-#
-# Add AVX code path, probably most controversial... The thing is that
-# switch to AVX alone improves performance by as little as 4% in
-# comparison to SSSE3 code path. But below result doesn't look like
-# 4% improvement... Trouble is that Sandy Bridge decodes 'ro[rl]' as
-# pair of µ-ops, and it's the additional µ-ops, two per round, that
-# make it run slower than Core2 and Westmere. But 'sh[rl]d' is decoded
-# as single µ-op by Sandy Bridge and it's replacing 'ro[rl]' with
-# equivalent 'sh[rl]d' that is responsible for the impressive 5.1
-# cycles per processed byte. But 'sh[rl]d' is not something that used
-# to be fast, nor does it appear to be fast in upcoming Bulldozer
-# [according to its optimization manual]. Which is why AVX code path
-# is guarded by *both* AVX and synthetic bit denoting Intel CPUs.
-# One can argue that it's unfair to AMD, but without 'sh[rl]d' it
-# makes no sense to keep the AVX code path. If somebody feels that
-# strongly, it's probably more appropriate to discuss possibility of
-# using vector rotate XOP on AMD...

-# SSE instruction sequence is first broken to groups of indepentent
-# instructions, independent in respect to their inputs and shifter
-# (not all architectures have more than one). Then IALU instructions
-# are "knitted in" between the SSE groups. Distance is maintained for
-# SSE latency of 2 in hope that it fits better upcoming AMD Bulldozer
-# [which allegedly also implements SSSE3]...
-#
-# Temporary registers usage. X[2] is volatile at the entry and at the
-# end is restored from backtrace ring buffer. X[3] is expected to
-# contain current K_XX_XX constant and is used to caclulate X[-1]+K
-# from previous round, it becomes volatile the moment the value is
-# saved to stack for transfer to IALU. X[4] becomes volatile whenever
-# X[-4] is accumulated and offloaded to backtrace ring buffer, at the
-# end it is loaded with next K_XX_XX [which becomes X[3] in next
-# round]...
