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.

When using native compiler exceptions, it isn't valid to use 
GetExceptionCode and GetExceptionInformation anywhere other than in the 
filter or handler blocks since it would be very hard for the compiler to 
work out where to retrieve the exception information from on the stack.

Therefore, remove the WINE_EXCEPTION_FILTER and WINE_FINALLY_FUNC macros 
which enabled GetExceptionCode, GetExceptionInformation and 
AbnormalTermination to be used inside of the functions they declared and 
fix up all callers to access the information directly.

Initialise *pcbRead to zero, if the parameter is not NULL.

wininet: Fix the return value check of SHGetSpecialFolderPathW in URLCacheContainers_CreateDefaults.

It returns a BOOL, not an HRESULT.

crypt32: Vista doesn't actually add duplicate usage identifiers; fix tests and change Wine to match.
