close the cab file even if no files are extracted.

Allow autoresizing rebar by PostMessage(hwndRebar, WM_SIZE, 0, 0) like

Attempt to start as a local service before attempting to start as a

Move the ANSI implementation of CLSIDFromString to ole16.c and change
CLSIDFromString to only deal with Unicode strings.

Extend ReadVariance to read the offset as well as the actual count,
since these always come in pairs.
Handle the variance not being present in ReadVariance and always call
it from the unmarshalling functions to simplify the code there and
also to fix a bug where the format pointer wasn't advanced properly
for complex arrays (introduced in the previous patch when implementing
variance).

Verify that the format string being passed into the complex array
functions is a complex array one.

Improve stubs for ScriptGetProperties and ScriptItemize.
Add stub for ScriptFreeCache.

Investigation with native msvcrt revealed that it is a wrapper for
GetFullPathName and the current implementation was crashing with older
mozilla installs if the path passed in was uninitialized.

Re-implement ITypeInfo::Invoke on top of DispCallFunc and
VariantChangeType instead of _invoke and _copy_arg.
