a916ff5cd8 Add support for an optional context parameter to TLS exporter
Allow an additional context value to be passed to TLS exporter as
specified in RFC 5705 section 4.

This does not yet implement it for the internal TLS implementation.
However, as currently nothing uses context yet, this will not break
anything right now. WolfSSL maintainers also stated that they are not
going to add context support yet, but would look into it if/when this is
required by a published draft or a standard.

a1f11e34c4 Use os_memdup()
This leads to cleaner code overall, and also reduces the size
of the hostapd and wpa_supplicant binaries (in hwsim test build
on x86_64) by about 2.5 and 3.5KiB respectively.

The mechanical conversions all over the code were done with
the following spatch:

    @@
    expression SIZE, SRC;
    expression a;
    @@
    -a = os_malloc(SIZE);
    +a = os_memdup(SRC, SIZE);
    <...
    if (!a) {...}
    ...>
    -os_memcpy(a, SRC, SIZE);

814f43cff5 EAP server: Simplify EAP method registration call
Free the allocated structure in error cases to remove need for each EAP
method to handle the error cases separately. Each registration function
can simply do "return eap_server_method_register(eap);" in the end of
the function.

3f1b792fbe EAP server: Disable TLS session ticket with EAP-TLS/TTLS/PEAP
The EAP server is not yet capable of using TLS session ticket to resume
a session. Explicitly disable use of TLS session ticket with
EAP-TLS/TTLS/PEAP to avoid wasting resources on generating a session
ticket that cannot be used for anything.

a80ba67a26 Check os_snprintf() result more consistently - success case
This converts os_snprintf() result validation cases to use
os_snprintf_error() in cases where success condition was used to execute
a step. These changes were done automatically with spatch using the
following semantic patch:

95f6f6a49d RADIUS/EAP server: Use longer username buffer to avoid truncation
If the peer provides a username with large part of it being non-ASCII
characters, the previously used buffers may not have been long enough to
include the full string in debug logs and database search due to forced
truncation of the string by printf_encode(). Avoid this by increasing
the buffer sizes to fit in the maximum result.

server, the inner MSCHAPv2 processing could have tried to dereference a
NULL pointer. Avoid this by handling this cleanly as an internal error
and reject the authentication attempt.

fd2f2d0489 Remove EAP-TTLSv1 and TLS/IA
These protocols seem to be abandoned: latest IETF drafts have expired
years ago and it does not seem likely that EAP-TTLSv1 would be
deployed. The implementation in hostapd/wpa_supplicant was not complete
and not fully tested. In addition, the TLS/IA functionality was only
available when GnuTLS was used. Since GnuTLS removed this functionality
in 3.0.0, there is no available TLS/IA implementation in the latest
version of any supported TLS library.

Remove the EAP-TTLSv1 and TLS/IA implementation to clean up unwanted
complexity from hostapd and wpa_supplicant. In addition, this removes
any potential use of the GnuTLS extra library.
