The actual user of this API is the UDP socket multiplexer which will
be added later.

The MSS might change between sending the a flight and possible
resend. We therefore have to be able to fragment the records
differently for resent.
Encoding and fragmenting of handshake record therefor needs to
be done independently.
With this change the handshake is encoded to it's full length
first, then queued to a flight. The fragmentation is handled
during assembly of the flights datagram.

Sync initial_state overall functionality with TLS and
add a few DTLS specific initalizers.

The flight concept was introduced by DTLS (RFC 4347) to optimize
the packing of DTLS records into UDP packets. This change
implments the flight concept in the the generic SSL connection
logic and add the queue logic to the TLS and DTLS stack.
The DTLS required resend handling is not implemented yet.
While the flight handling is only required for DTSL, it turns
out that the same mechanism can be usefull to TCP based TLS as
well.
With the current scheme each TLS record will be mapped into a
separate TCP frame. This causes more TCP frames to be generate
that necessary. On fast network this will have no impact, but
reducing the number of frames and thereby the number of
round trips can result in significant speedups on slow and
unreliable networks.

available_signature_algs is also needed for DTLS, move it
into a shared place and export it.

ssl: Use cipher suite's PRF in prf/5
|
|
|
|
|
|
Use the negotiated cipher suite's PRF algorithm in calls to
ssl:prf/5, rather than a hard-coded one.
For TLS 1.0 the PRF algorithm was hard-coded to MD5/SHA1. This
was correct 100% of the time.
For TLS 1.1 and 1.2 the PRF algorithm was hard-coded to SHA256.
This was correct only some of the time for TLS 1.2 and none of the
time for TLS 1.1. Because the TLS handshake code calls tls_v1:prf/5
through another path, the handshaking process used the negotiated
PRF and did not encounter this bug.
A new test (prf) has been added to ssl_basic_SUITE to guard against future
breakage.

gen_tcp:recv allows this, and if you're doing something like
Transport:recv(Socket, 0, 0), TCP will work and SSL will exit with
function_clause
There were other cases of this throughout the module. This PR cleans
them all up.

Turns out we can not count on the "hashsigns" sent by the client and
the supported "hashigns" sets to have required properties of ordsets.

These functions call getstat on the underlying TCP socket.
The only way to do this before now was to use a hack, either
by looking inside the #sslsocket{} record directly, or by
not using the SSL listen/accept functions and upgrading
from a TCP socket that is kept around for the purpose of
calling getstat later on.

The selection of CA cert files in ssl_ECC_SUITE and ssl_test_lib
ought to be refactored, it is quite confusing.
But use this workaround until we get time to make a refactor.

Some shells i.e the bash emulating sh regard curly brackets
as special characters so e.g {a,b,{}} is expanded to a b {} which
is by erlang regarded as 3 arguments instead of a 3-tuple.
Other shells e.g Bourne classic /bin/sh, the ash/dash variants
and public domain Korn shell all avoid this surprise.
