CreateFileA/CreateFileW return type 'HANDLE' while TIFFFdOpen() takes 'int',
which is formally incompatible and can even seemingly be of different size:
HANDLE is 64 bit under Win64, while int is still 32 bits there.
However, only the lower 32 bits of a HANDLE are significant under Win64 as,
for interoperability reasons, they must have the same values in 32- and
64-bit programs running on the same system, see
https://docs.microsoft.com/en-us/windows/win32/winprog64/interprocess-communication
Because of this, it is safe to define the following trivial functions for
casting between ints and HANDLEs, which are only really needed to avoid
compiler warnings (and, perhaps, to make the code slightly more clear).
Note that using the intermediate cast to "intptr_t" is crucial for warning
avoidance, as this integer type has the same size as HANDLE in all builds.
