Make the CT code library context aware

Add the new functions CTLOG_STORE_new_with_libctx(),
CTLOG_new_with_libctx() and CTLOG_new_from_base64_with_libctx() to pass
in the library context/property query string to use a library context
is to be used.

We also add the function CT_POLICY_EVAL_CTX_new_with_libctx() to enable
the creation of a CT_POLICY_EVAL_CTX to be associated with a libctx and
property query string.
