Fix building with "trace"

[fancycode]

This should hopefully fix the remaining of #352.

Please wait for Travis to finish before merging this to see if anything else needs to be changed.

@mattn Building now works for all cases but libsqlite3 trace:

could not determine kind of name for C.SQLITE_DETERMINISTIC
could not determine kind of name for C.SQLITE_TRACE_CLOSE
could not determine kind of name for C.SQLITE_TRACE_PROFILE
could not determine kind of name for C.SQLITE_TRACE_ROW
could not determine kind of name for C.SQLITE_TRACE_STMT
could not determine kind of name for C.sqlite3_expanded_sql
could not determine kind of name for C.sqlite3_trace_v2

Is this supposed to work or should I remove it from the Travis build matrix? If it is unsupported it would be better to not build the tracing code if libsqlite3 is defined (even it also trace is defined).

Thank you. But, I modified master branch already because it will need more fixes.

You should at least merge / cherry-pick this commit:
b11c615

Otherwise the combination of libsqlite3 trace is not tested correctly in Travis (only sets libsqlite3). Also I rebased to your latest changes on master...

[mattn]

merged. thank you

libsqlite3 on travis is too old.
