cabinet: Replace strcasecmp call with lstrcmpiA as strcasecmp isn't portable and doesn't take into account the current codepage.

Also make the DINPUT_instance static.

Provide a fallback case for other compilers to avoid C_ASSERT being 
undefined and causing an error.

When using native compiler exceptions, the previous method of doing 
this, __EXCEPT(NULL), would expand to __except( 
(NULL)(GetExceptionInformation())) which doesn't compile as NULL isn't a 
function.

So add a new macro, __EXCEPT_ALL, which works correctly both when using 
native compiler exceptions and without and which makes the meaning of 
code in which it is used clearer.

Previously, the code would return any monitor found, regardless of 
whether it intersected the given rect or was the nearest monitor. This 
is fixed by adding a new flag that causes monitor_enum to only find the 
nearest monitor if MONITOR_DEFAULTTONEAREST is specified.

Also add a trace for MonitorFromWindow, since it is called in many 
places within user32 and so can't be traced using a relay trace.
