[task #16114] Print warning where integer overflow happens

[Siyang He]

Follow-up Comment #10, task #16114 (project gnuastro):

Excellent Mohammad!

distcheck passed and you can find my changes at
https://codeberg.org/decaf/gnuastro/src/branch/overflow-check

Overview of changes:
- lib/gnuastro/arithmetic.h: I define the flag
GAL_ARITHMETIC_FLAG_OVERFLOW_CHECK.
- lib: I add "overflow_check" versions of the plus, minus, multiply, and
divide operations.
- lib/arithmetic.c: I call the appropriate version (check for overflow vs.
don't check) of each arithmetic function from arithmetic_binary().
- lib/gnuastro-internal/arithmetic-binary.h: I define a few more levels of
macros for overflow checks.

I would appreciate your feedback. Thank you!
