Fix overiding of return value.
If MBEDTLS_KEY_EXCHANGE_SOME_PSK_ENABLED is defined, then the return value will be overridden by the extra code running after the removed return instruction.

If query_config is used only the config value is printed.
The extra code running after the removed return instruction should not generate any output. Only the read config value must be printed.

e58a630cb0 Add support for password protected key file to ssl_server2
The example application programs/ssl/ssl_server2 allows the
configuration of up to two CRTs through the command line
parameters
- crt_file, key_file
- crt_file2, key_file2.
However, password protected key files are not supported.

This commit adds command line options
- key_pwd
- key_pwd2
which allow to specify passwords for the key files specified
in key_file and key_file2, respectively.

65d8c2651d Show failure in ssl-opts.sh when key export fails
1. When `ssl_server2` export key functionality fails,
don't exit the server, but reset it, to have the
server recover for next connection.
2. Add text filters for `export keys functionality` test in ssl-opt.sh
to check for additional output, to verify if the export suceeded.

This was discovered in the `ssl-opt.sh` script, where the server exited,
before the test tried to kill the server priocess, resulting in a
`kill: No such process` message.

Fixes #2662

b2971ff942 Strict C99: don't use extremely large string literals
Don't use string literals that are longer than 4095 bytes, which is
the minimum that C99 compilers are required to support. Compilers are
extremely likely to support longer literals, but `gcc -std=c99 -pedantic`
complains.

Split the maximum fragment length into two - an input and output MFL
Since the server might want to have a different maximum fragment length
for the outgoing messages than the negotiated one - introduce a new way of
computing it. This commit also adds additional ssl-opt.sh tests ensuring
that the maximum fragment lengths are set as expected. 
mbedtls_ssl_get_max_frag_len() is now a deprecated function,
being an alias to mbedtls_ssl_get_output_max_frag_len(). The behaviour
of this function is the same as before.

eccd888717 Rename identifiers containing double-underscore
Rename identifiers containing double-underscore (`__`) to avoid `__`.
The reason to avoid double-underscore is that all identifiers
containing double-underscore are reserved in C++. Rename all such
identifiers that appear in any public header, including ssl_internal.h
which is in principle private but in practice is installed with the
public headers.

This commit makes check-names.sh pass.

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.

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.

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.

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.

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.
