Update iv and len context pointers manually when reallocating buffers

Browse Source 
These fields might be shifted accordingly in `ssl_parse_record_header()`
when receiving a connection with CID, so they require a manual update
after calling the generic `mbedtls_ssl_reset_in_out_pointers()`.

This commit also adds a regression test which is run by all.sh.
