a665750f4c prepare and dispatch mdp frames for rhizome over mdp. 
still need to set bodies of frames, and schedule call backs,
and handle the requests when received.

4450116472 Refactor string functions, add str_fromprint() 
Move lots of non-Serval-specific string functions from "serval.h"/dataformats.c
to "str.h"/str.c.

Add str_fromprint() function that reverses the effect of toprint(): interprets
escape sequences in the source string "\n\t\r\0\xHH\\" and replaces them with a
single char in the destination string.

499c4018bf Imported ref10/ implementation of crypto_sign from supercop-20120525 
as recommended a while back by Dan Bernstein as offering the fastest
implementation of the crypto_sign() primitives for ARM.
Indeed this implementation IS faster. See comparison below for a
Rock 500 handset (800MHz(?) ARM6, no NEON):

Original ref/ implementation on an R500 stock rom (non-rooted)::
mean signature generation time = 96.80ms
mean signature verification time = 272.20ms

ref10/ implementations on an R500 stock rom (non-rooted):
mean signature generation time = 4.00ms
mean signature verification time = 13.00ms

Approximately 20x speed up, just like that :)

0e5c5e0e98 More work on dnahelper, almost done 
Servald starts DNA helper, receives startup ACK, sends requests, receives
responses, handles malformed helper responses, echoes dnahelper stderr lines to
log, sends MDP reply packet, waits for dead helper process, all asynchronously.
Shuts down helper process during servald shutdown.

Remaining issues:
 - Does not impose a timeout on helper responses.
 - Only the first URI is reported by the "dna lookup" command.

SET_NONBLOCKING(), SET_BLOCKING(), WRITE_STR() are now set_nonblock(),
set_block() and write_str() respectively, all of which log an error before
returning -1.  There are other useful methods: write_all() treats anything less
than all bytes written as an error; write_nonblock() treats EAGAIN and EINTR as
zero bytes written, and a combination: write_all_nonblock().
