This makes the implementation less likely to provide useful timing
information to potential attackers from comparisons of information
received from a remote device and private material known only by the
authorized devices.

The internal TLS server implementation and RADIUS server implementation
in hostapd can be configured to allow EAP clients to be tested to
perform TLS validation steps correctly. This functionality is not
included in the default build; CONFIG_TESTING_OPTIONS=y in
hostapd/.config can be used to enable this.
When enabled, the RADIUS server will configure special TLS test modes
based on the received User-Name attribute value in this format:
<user>@test-tls-<id>.<rest-of-realm>. For example,
anonymous@test-tls-1.example.com. When this special format is used, TLS
test modes are enabled. For other cases, the RADIUS server works
normally.
The following TLS test cases are enabled in this commit:
1 - break verify_data in the server Finished message
2 - break signed_params hash in ServerKeyExchange
3 - break Signature in ServerKeyExchange
Correctly behaving TLS client must abort connection if any of these
failures is detected and as such, shall not transmit continue the
session.

This allows the internal TLS implementation to write log entries to the
same authlog with rest of the RADIUS server and EAP server
functionality.

This same design is used in both the server and the client roles in the
internal TLS implementation. Instead of duplicated implementation, use a
helper function.

Add support for generating and verifying RFC 3447 RSASSA-PKCS1-v1_5
style DigestInfo for TLS v1.2 CertificateVerify. For now, this is
hardcoded to only support SHA256-based digest.

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.
