and their tests.

ReadDirectoryChangesW.
Add a test for it.

Rewrote virtual modules handling so that it's an option to either PE
or ELF modules rather than a specific type.

done in winedos if necessary.

- check mark is drawn left of a bitmap;
- if a MNS_CHECKORBMP-style menu has a checkmark, do no draw any bitmap;
- space for the popup arrow is also reserved for non popup items;
- implement the MNS_NOCHECK style.

- Use DrawText in stead of GetTextExtendPoint32, to properly measure
  strings with ampersands like "&File";
- Fix mess with strings with an embedded tab;
- In case of a menu bar, two extra pixels are added if the item has
  both a bitmap and string.

Replace some #defined constants by values calculated from windows
metrics.

- Move sending WM_MEASUREITEM message for HBMMENU_CALLBACK bitmaps to
MENU_GetBitmapItemSize();
- Save the received bitmap size in the menu item structure as it will
need to be sent in the WM_DRAWITEM message;
-  Move sending WM_DRAWITEM message for HBMMENU_CALLBACK bitmaps to
MENU_DrawBitmapItem();
- This also means that HBMMENU_CALLBACK bitmaps are now supported in
menu bars.

level of some large if statements in the drawing code. Some updates to
the comments.

the relative location of the wine libraries.

- remove unused argument from functions
- print the pointer in the str_array_push TRACE to be able to distinguish
  the different arrays.
- comment and white space cleanups

Add some tests for unDName() checking:
- data type modifiers A,B,P,Q,R,S
- literal strings
- back references to names

Use a separate array/stack for the back references to names as
sym->stack is used to push temporary strings to it which breaks back
referencing in some occasions (26 symbols in the mfc42 dll).  During
this cleanup get_class() a little bit.

unDName: Move the code to parse a literal string from get_class() to a
separate function. Add some error handling to the new function.

In test_demangle use a custom strcmp that treats multiple spaces as
single space. __unDName() from older msvcrt (including W2K it seems)
emit in some places 2 spaces instead of one. Fixes 20 failing tests on
those old Windows versions.

Change the apartment model field to a boolean that just specifies
whether the apartment is multi-threaded or not and fix up all the
places where this is used.
Fixes a bug where we would return an error if the previous apartment
model passed into CoInitializeEx matches the new apartment model, but
additional optimisation flags are specified.

criteria (it was mainly doing the opposite).

E_NOTIMPL in Windows as well.

Implement CertGetEnhancedKeyUsage, CertSetEnhancedKeyUsage,
CertAddEnhancedKeyUsageIdentifier, and
CertRemoveEnhancedKeyUsageIdentifier.
