use 64-bit arithmetic instead of 32-bit

Add suffix LL and ULL to various constants in order to give the compiler complete information about the proper arithmetic to use. Such constants are used in contexts that expect expressions of type u64 (64 bits, unsigned) and s64 (64 bits, signed).

The mentioned expressions are currently being evaluated using 32-bit arithmetic, wich in some cases can lead to unintentional integer overflows.

This patchset addresses the following "Unintentional integer overflow" Coverity reports:
CIDs: 200604, 1056807, 1056808, 1271223, 1324146
CIDs: 1392628, 1392630, 1446589, 1454996, 1458347

Thank you

Changes in v2:
- Update subject and changelog to better reflect the proposed code changes.
- Add suffix ULL and LL to constants instead of casting variables.
- Extend the proposed code changes to other similar cases that had not previously been considered in v1 of this patchset.

Changes in v3:
- Mention the specific Coverity report in all commit messages.
