Move handling of nested exceptions completely in the
catch_function_nested_handler().  If a new exception was thrown inside
a catch block destroy the old exception object, if it is a rethrow
re-propagate the previous object.

- read strings from left to right (PathGetDriveNumberW)
- don't access buffers before they are filled (SHGetPathFromIDListW)
- fill buffers & variables on all paths (SHELL_FindExecutable)
- handle error condition (unix_fs)
- don't shoot in the blind for AW APIs (tests/shelllink.c)

Add some missing MAPI prototypes to mapi.h (spotted by winapi_check)
and include it where they are implemented.
Make mapi.h and mapix.h compatible. gcc does not like macros and
prototypes to be redefined so this involved protecting against
multiple definitions.
Fix the MAPISendMail() implementation prototype.

Removed todo flag from affected FR_MATCHCASE tests.

Implement the DG_IMAGE/DAT_IMAGEMEMXFER/MSG_GET code path. Along with
a number of corrections and improvements to allow the actual aquiring
of images to succeed.

Find the proper modref in that case based on the dlopen handle.

This ensures that we never fixup imports twice on the same dll.

Fixed the startup_info signaled state to avoid blocking the parent
process when the child crashes on startup.

when loadorder is set to builtin only.

The key function is to calculate the total of the ABC widths of the
characters converted to gylphs by ScriptShape.

Let the few existing parts which need the capabiliteis use the WineD3D
capability structure (gl_info). This info structure contains next to
'flags' inidicating certain features also all GL/GLX functions
pointers. Because D3D8 moves over to the wined3d gl_info structure all
the gl prototypes in d3dcore_gl.h were unneeded and removed.

Fixed the cpMin/cpMax validation code for EM_FINDTEXT.
Removed todo flag from affected EM_FINDTEXT tests.

trio of functions.

Stream methods called after parent object has been closed correctly
return STG_E_REVERTED.
Stream refcounting fixed. Now can safely call IStorage destructor
before IStream destructor and guarantee file will be closed.

Fix up permissions when opening streams in storage objects when
storage object has been opened in transacted mode.

Add them to or remove them from existing recursive watches.
