Modified Files:
	src/ssh/test/test_conn.c test_transport.c
Log Message:
Test the last "practically untestable" branches

All four turned out to be testable:

- aes256_ctr/ctx_member_null: cbd non-NULL but cbd->ctx is NULL
  (second half of OR condition at line 46)
- aes256_ctr/encrypt_update_fail: arm ossl countdown AFTER init
  succeeds so EVP_EncryptUpdate fails mid-operation
- hmac_sha2_256/cleanup_null: call cleanup with NULL ctx
- hmac_sha2_256/generate_failure: arm ossl countdown AFTER init
  succeeds so EVP_MAC operations fail mid-generate
- test_window_add_overflow: set local_window near UINT32_MAX,
  send_window_adjust with enough to overflow Ä clamps to UINT32_MAX
