user32: When all items in a menu have either a bitmap or text but not both, then texts should be aligned with the bitmaps.

This reverts commit 0addd3ba.
It doesn't fix anything, it just hides the bug.

The application AutoGK was getting the length of the text with
WM_GETTEXTLENGTH to allocate an appropriate buffer size, but then
claimed the buffer was twice the size when sending WM_GETTEXTEX.  This
caused the memcpy call to overflow the actual buffer since the count
is based on the size of the buffer alone, regardless of the amount of
text retrieved.

ME_GetTextEx directly handles EM_GETTEXTEX, and previously a NULL buffer
would be dereferenced, and a 0 buffer length would cause nCount an
underflow in the nCount value which would allow a buffer overflow to
occur.

kernel32/tests: Skip GetVolumeInformation test on current directory when running on a root directory.

Passing NULL to glCompressedTexImage2DARB() doesn't work particularly well
when both client storage and PBOs are enabled. Also, two years is long enough
to give driver developers a chance to fix the bug this was supposed to work
around.

wined3d: Don't use the GL texture flags to determine if a format is a depth stencil in CheckDepthStencilCapability().

The OpenGL implementation might not support ARB_depth_texture, but that
doesn't mean we can't use the format for the depth buffer.

"surface" might point to the frontbuffer while we're rendering to the
backbuffer, etc.

Fixes building on Snow Leopard.
