Gilles Peskine 4e8b594002 Fix uninitialized variable in an edge case
If `context_buf = mbedtls_calloc( 1, buf_len )` failed,
`context_buf_len` was not initialized. Noticed by
`gcc -Os -Werror=maybe-uninitialized`.

This was only a problem in ssl_server2 (a test program), only with
MBEDTLS_SSL_CONTEXT_SERIALIZATION enabled.

Jaeden Amero 63d813d258 ssl: Disallow modification of hello.random by export
Make client_random and server_random const in
mbedtls_ssl_export_keys_ext_t, so that the key exporter is discouraged
from modifying the client/server hello.

Update examples and tests use const for hello.random as well, to ensure
that the export callbacks are of the proper type.

Fixes #2759

Hanno Becker 48f3a3d101 Add NSS keylog support to ssl_server2 and ssl_client2
This commit adds command line options

- nss_keylog=0/1
- nss_keylog_file=FILENAME

to the example programs ssl/ssl_client2 and ssl/ssl_server2 which
allow to print and export the session keys in the NSS keylog
for debugging purposes.

Manuel Pégourié-Gonnard 9df5a82079 Actually reset the context on save as advertised
Also fix some wording in the documentation while at it.

Manuel Pégourié-Gonnard 13c8e68477 Change requirements for setting timer callback
The code wants timer callbacks to be set (checked in fetch_input()), and can't
easily check whether we're using nbio, so it seems easier to require the
callbacks to be always set rather than only with nbio as was previously done.

Manuel Pégourié-Gonnard 3309a67996 Fix memory leak in client/server2
context_buf was never free()d. Moreover, since we want to free it on error
paths as well, and even properly zeroize it in order to demonstrate good
memory hygiene, we need to make it and its length main()-scoped.

Manuel Pégourié-Gonnard a88399c091 Improve demo/testing code in client/server2
Previously it was missing reset in case 1, and in case 2 the code was never
executed as the option value was reset to 0.

Tighten checking of return values of save(NULL, 0) now that it works.

Also, improve the printed output as well as the comments.

I checked manually that everything now works and fail in the expected way:
save, reset-or-reinit and load all succeed, but the subsequent read or write
fails.

Gilles Peskine 3abbcedc68 Remove mbedtls_param_failed from programs
All sample and test programs had a definition of mbedtls_param_failed.
This was necessary because we wanted to be able to build them in a
configuration with MBEDTLS_CHECK_PARAMS set but without a definition
of MBEDTLS_PARAM_FAILED. Now that we activate the sample definition of
MBEDTLS_PARAM_FAILED in config.h when testing with
MBEDTLS_CHECK_PARAMS set, this boilerplate code is no longer needed.
