Since we support only SHA256 (and not the default SHA1) with TLS v1.2,
the signature_algorithms extensions needs to be added into ClientHello.
This fixes interop issues with the current version of OpenSSL that uses
the default SHA1 hash if ClientHello does not specify allowed signature
algorithms.

Commit 94f1fe6f63 ('Remove master key
extraction from tls_connection_get_keys()') left only fetching of
server/client random, but did not rename the function and structure to
minimize code changes. The only name is quite confusing, so rename this
through the repository to match the new purpose.

This is not needed anymore with the tls_connection_prf() being used to
handle all key derivation needs. tls_connection_get_keys() is a bit
misnamed for now, but it is only used to fetch the client and server
random for Session-Id derivation.

Now that the internal AES implementation supports 256-bit keys, enable
use of the TLS cipher suites that use AES-256 regardless of which crypto
implementation is used.

Reassemble partial TLS records to make the internal TLS client
implementation more convenient for stream sockets.

Return number of user input bytes from tlsv1_record_receive() to
move this detail into the proper record layer processing. In addition,
ignore unknown content types at record layer and allow processing to
continue after warning level TLS alerts to provide minimal workaround
for closure alerts.

This phase1 parameter for TLS-based EAP methods was already supported
with GnuTLS and this commit extends that support for OpenSSL and the
internal TLS implementation.
Clean up the internal TLS implementation by removing conditional
build blocks for (mostly) EAP-FAST specific functionality. This
will increase the size a big for non-EAP-FAST builds, but is quite
helpful in making src/tls/libtls.a with single build options. If
the potential size reduction is considered significant in the future,
this can be reconsider with a more library compatible way (e.g.,
external file with registration function, etc.).
In addition, start ordering header file includes to be in more
consistent order: system header files, src/utils, src/*, same
directory as the *.c file.
When using the internal TLS implementation, EAP-FAST unauthenticated
provisioning ends up proposing multiple cipher suites. It looks like
Cisco AP (at least 350 and 1200 series) local authentication server does
not know how to search cipher suites from the list and seem to require
that the last entry in the list is the one that it wants to use.
However, TLS specification requires the list to be in the client
preference order. As a workaround, ass anon-DH AES-128-SHA1 again at the
end of the list to allow the Cisco code to find it.
This fixed EAP-FAST provisioning with the following IOS version:
Cisco IOS Software, C350 Software (C350-K9W7-M), Version 12.3(8)JEA3,
RELEASE SOFTWARE (fc2)
