SSL test programs: allow for test hooks init and error reports

Browse Source 
Create utility functions to set up test hooks and report errors that
the test hooks might detect. Call them in ssl_client2 and ssl_server2.

Test hooks are potentially enabled by compiling with
MBEDTLS_TEST_HOOKS.

This commit only sets up the functions. It doesn't make them do
anything yet.
