* We replace `mLastUsedUnicodeDirectory` and its manual memory management with
a `UniquePtr` named `sLastUsedUnicodeDirectory`
* We remove `AutoRestoreWorkingPath`, as it never was actually necessary and
was left in, "just in case."
* We remove the timeout stuff, as that never actually worked, at least with
the current implementation of the file picker; perhaps it worked with the
legacy file picker APIs, but it doesn't work with the Vista+, COM-based stuff.
* We also get rid of `IFileDialogEvents`, as all of that stuff was needed for
timeouts. It also adds additional complexity that impairs our ability to
implement out-of-process file pickers in a future bug.
* We replace `do_CreateInstance("@mozilla.org/file/local;1")` with
`NS_NewLocalFile`.
* We add `HRESULT` error handling to all of the method invocations on COM
interfaces.
* We replace `CLSCTX_INPROC` with `CLSCTX_INPROC_SERVER` in `CoCreateInstance`
calls.
* We remove `CoInitialize` and `CoUninitialize` calls. Those have been
unnecessary ever since we added `mscom::ProcessRuntime` instantiation during
startup.
* We add a missing check for private browsing mode in
`nsFilePicker::RememberLastUsedDirectory`.
