Fixes: correct check on truncation failure. Reinit IRD on statement closing. Logging format descriptors (#170)

* fix: only fail time*/str conversion on truncation

The timestamp/time to string truncation needs to fail only if current
status code (for current column) indicates that truncation occured; so
status code has been added to the branching evaluation.

Previously, only the current diagnostic code was used in the decision
(and checked if it indicated truncation), which was incorrect since this
could have been set by the conversion of a previous column in same row.

* fix: re-init IRD headers on statement close

On statment closing the IRD descriptor's headers should be
reinitialized.
The fix is for good house keeping, the defect didn't have a
practical impact, since the IRD is cleared also before adding a new
result set; furthermore, a new result set added to an already-used IRD
would only occur if a statement handle is re-prepared, which happens
very rarely (generally a client app would allocate a new handle for a
new query).

The commit also switches a few catalog functions to using
SQLExecDirect(), instead of dupplicating its code.

* fix: correct logging format specifiers

Correct some format specifiers for logging, mostly s/zd/zu for size_t
types.

Cherry-pick merging:
- truncation failure check not applicable.
