Fix some new errors and a warning in cryptotest.

Browse Source 
- Use a new 'char *key' to allocate storage for keys and assign the
  pointer to the session2_op 'const char *' members after the key is
  initialized.
- Mark the 'find' variable used in crfind() static so that crfind()
  doesn't return a pointer to stack garbage.
