This is essentially a backout of bug 506805, followed by changing the locking
protection rules to only protect mCancelRequested writing on the calling thread,
and reading on the background thread.

This removes the use of the shared mutex in AsyncExecuteStatements. We now rely
on PR_AtomicSet and the volatile keyword. This results in zero lock contention
between the calling thread and the background thread if cancel is ever called.

This fixes the code to use functions that expect milliseconds instead of
microseconds, and updates to use the new TimeStamp and TimeDuration class.
r=asuth
Stop calling any SQLite functions that would acquire the database mutex inside
Connection::ExecuteAsync. Additionally, do not actually bind parameters when
the binding functions are called, but rather when we execute (so for async
statements, that will happen on the background thread creating no mutex
contention with the main thread).
r=asuth
Improves the asynchronous API by allowing multiple parameters to be bound before
executing it. The statement is then executed with each set of parameters
asynchronously.

Renames the files to be more representative to what they actually contain. This
also updates the files to follow the storage style guidelines.
