Avoid warnings about casts between HANDLE and int in Win64 builds
...
Add helper thandle_{from,to}_int() functions performing the casts
between (64-bit, under Win64) thandle_t and (32-bit, always) int in a
way that doesn't trigger compiler warnings.
Also explain why suppressing these warnings is the right thing to do.

Fix integer overflow in _TIFFCheckMalloc() and other implementation-defined behaviour (CVE-2019-14973)
...
_TIFFCheckMalloc()/_TIFFCheckRealloc() used a unsafe way to detect overflow
in the multiplication of nmemb and elem_size (which are of type tmsize_t, thus
signed), which was especially easily triggered on 32-bit builds (with recent
enough compilers that assume that signed multiplication cannot overflow, since
this is undefined behaviour by the C standard). The original issue which lead to
this fix was trigged from tif_fax3.c
There were also unsafe (implementation defied), and broken in practice on 64bit
builds, ways of checking that a uint64 fits of a (signed) tmsize_t by doing
(uint64)(tmsize_t)uint64_var != uint64_var comparisons. Those have no known
at that time exploits, but are better to fix in a more bullet-proof way.
Or similarly use of (int64)uint64_var <= 0.
