Log Message:
-----------
* lib/oci8/oci8.rb: add OraNumber#to_json and OraDate#to_json.
* lib/oci8/metadata.rb: define char_used?, char_size, fsprecision
    and lfprecision methods to subclasses of OCI8::Metadata::Base
    onln when Oracie 9i or upper. They ara unavailable on Oracle
    8.1 or lower.
