Mac: Avoid [AVFoundationBundle load] every time that IsAVFoundationSupported() is called

Change the result of AVFoundationGlue::IsAVFoundationSupported() to
be evaluated only once, and return the static bool every time.

The order of the flag evaluation changes subtly:
- First we check for OS version: there's no AVFoundation
in Mac OS X < 10.7.
- Second comes the check for command line flag for explicit
AVFoundation disabling (hence using QTKit).
- Third and final, the library tries to be loaded

IndexedDB: Don't timeout read-only transactions

Chrome introduced a transaction timeout to deal with potentially wedged
renderers (e.g. JS execution halted, etc) failing to complete transactions,
leaving the browser's transaction queue in a bad state. This was done
for all transactions, but since read-only transactions don't hold up
the queue it's safe to ignore them, which can reduce false-positives.
