Move the handshake creating code to a function. 
Fixed another instance where it was not sent.

Protocol implementation is starting to look ok. 
Still need to decide exactly how data packets will work though.

Some more work done on the middle network protocol. 
Handshake most likely has no more possible flaws to it, next thing
to do is to do the same with the data packets.

Wrote a couple more functions.

Major cleanups. 
Fixed circular dependency between DHT and net_crypto: DHT no longer
depends on net_crypto.

Moved the crypto request packets functions to crypto core and DHT.

Cleaned up/added some defines that can be used to get the true maximum
length of things like the friends request message.

MAX_DATA_SIZE has been replaced in most places by more appropriate defines.

9c6a8432ce Crypto related cleanups. 
Moved Bunch of functions from net_crypto to crypto_core.

decrypt_data_fast and decrypt_data_symmetric were the same thing
therefore, removed decrypt_data_fast.

Replaced all the crypto_secretbox_* defines with the equivalent
crypto_box_* one.

New define: crypto_box_KEYBYTES that is equal to
crypto_box_BEFORENMBYTES.

0a4c3d7e2e Move unix_time(), id_cpy()/id_eq(), is_timeout() to util.* 
unix_time():
- returns local value for current epoch
- value is updated explicitly with unix_time_update() called at new_DHT()/doMessenger()/do_DHT()

is_timeout():
- uses the local value for current epoch

id_cpy()/id_eq() => id_copy()/id_equal():
- centralized duplicate definitions
- replaced (most) memcpy()/memcmp() of (*, *, CLIENT_ID_SIZE) with id_copy()/id_equal()

e092eee869 Allow to build vs nacl instead of libsodium 
By default libsodium is used. Only if --enable-nacl is specified, then
nacl will be used instead of libsodium.

Pass locations of nacl headers and libraries by using the following
options:

--with-nacl-headers=/home/me/somewhere/nacl-20110221/build/469/include/amd64/
--with-nacl-libs=/home/me/somewhere/nacl-20110221/build/469/lib/amd64/

e658892793 Rename core directory because of autoconf name clash 
While doing the checks configure might generate "core" files and will
then try to remove them. Having a "core" directory generates an error
while runing the configure script.

There's no workaround but to rename the core directory.
