458756 - Use raw sqlite3_stmt pointers instead of the mozStorageStatement object for async statements

Status: RESOLVED FIXED

(Core :: SQLite and Embedded Database Bindings, defect)

Description

[Shawn Wilsher :sdwilsh]

We end up doing a lot of work that we don't have to do by wrapping it, and it also means we may not get accurate errors back (due to threading timing issues).  We could add more locks, but we don't need to if we use a raw statement.

We also end up doing less work on the calling thread (addref and release, among other things).

Probably worth nulling out mStatement here.
