Previously after sending or receiving a close_notify we would
reset all handshake state and basically ignore anything the peer sent.
Now we detect any garbage that might arrive after.

Avoids passing pointers down the call stack.
Also add a second buffer to hold the record plaintext, which
avoids an extra alloc+free per record.

- BoGo sends unparseable OCSP responses, so we have to accomodate for
this by delaying decoding until verification and simply ignoring
OCSP responses that we can't parse.
- Check that there is no trailing garbage at the end of various messages.
- Don't send empty SNI
- Check the TLS record header versions (previously ignored)
- For CBC 1/n-1 splitting split every record instead of just first.
I think this is not a problem but it is what BoGo expects.
- New Channel::application_protocol virtual (previously was
implemented on both Client and Server but not shared).
- Changes to resumption version handling.
- Fix server version selection when newer versions are disabled.
New policy hooks added in service of BoGo:
- maximum_certificate_chain_size gives the maximum cert chain in bytes
that we'll accept.
- allow_resumption_for_renegotiation specifies if a renegotiation
attempt can be simply (re-)resumed instead.
- abort_handshake_on_undesired_renegotiation - previously we just
ignored it with a warning alert. Now behavior is configurable.
- request_client_certificate_authentication
- require_client_certificate_authentication

Defined in build.h, all equal to BOTAN_DLL so ties into existing
system for exporting symbols.

Renames a couple of functions for somewhat better name consistency,
eg make_u32bit becomes make_uint32. The old typedefs remain for now
since probably lots of application code uses them.

Make TLS::Channel::m_callbacks a reference, so deriving from TLS::Callbacks works
Split out the compat (std::function) based interface to Compat_Callbacks.
This avoids the overhead of empty std::functions when using the virtual
interface, and ensures the virtual interface works since there is no
callback path that does not involve a vtable lookup.
Rename the TLS::Callback functions. Since the idea is that often an owning
class will pass *this as the callbacks argument, it is good to namespace
the virtual functions so as not to conflict with other names chosen by
the class. Specifically, prefixes all cb functions with tls_
Revert changes to use the old style alert callback (with no longer used data/len
params) so no API changes are required for old code. The new Callbacks interface
continues to just receive the alert code itself.
Switch to virtual function interface in CLI tls_client for testing.
Inline tls_server_handshake_state.h - only used in tls_server.cpp
Fix tests - test looked like it was creating a new client object but it
was not actually being used. And when enabled, it failed because the queues
were not being emptied in between. So, fix that.

- Added legacy constructor support for TLS::Channel, TLS::Client,
TLS::Server.

- extracted inner class TLS::Channel::Callbacks to stand-alone class
TLS::Callbacks.
- provided default implementations for TLS::Callbacks members executing
calls to std::function members for backward compatibility.
- applied changes to cli, tests and TLS::Channel related classes to be
compatible with new interface.

- Removed deprecated TLS-Alert-Callback parameters.
- Fixed improper naming of accessor for ALPN-Strings in tls_client.h
- Fixed erroneous indentation on Ciphersuite Constructor.

-reduced number of parameters in various methods
-reduced cyclomatic complexity (McCabe-Metric)
-removed "TLSEXT_HEARTBEAT_SUPPORT" from tls_extensions.h (leftover
from heartbeat extension removal?)

The signature of the alert callback remains unchanged to avoid
breaking applications, though now the buffer parameter is never set.

Use constant time operations when checking CBC padding in TLS decryption
Fix a bug in decoding ClientHellos that prevented DTLS rehandshakes
from working: on decode the session id and hello cookie would be
swapped, causing confusion between client and server.
Various changes in the service of finding the above DTLS bug that
should have been done before now anyway - better control of handshake
timeouts (via TLS::Policy), better reporting of handshake state in the
case of an error, and finally expose the facility for per-message
application callbacks.

with the setting set in the constructor. This prevents various surprising
things from happening to applications and simplifies record processing.
