Fixed bug #46781 (BC math handles minus zero incorrectly)

Actually, there is no negative zero at all. We obey Postel's law, and
still accept negative zeroes, but we store them as positive zeroes
after the conversion from string, i.e. we normalize before further
processing.

Fixed bug #73730 (textdomain(null) throws in strict mode)

The $text_domain parameter may be NULL, which we have to cater to
explicitly with regard to strict_types.

Fixed bug #75178 (bcpowmod() misbehaves for non-integer base or modulus)

Since `bcpowmod()` does not support non-integral operands, we have to
truncate these in addition to emitting a respective warning. We also
have to work with the truncated values in the following.

We recognize that the division by one to enforce the truncation is
actually overkill, but we stick with it for now, and shall tackle the
issue for PHP 7.3.

Fix typo in zend_symtable_add_new() API name

Fixed bug #54598 (bcpowmod() may return 1 if modulus is 1)

`x mod 1` is always zero; we have to take the scale into account,
though.

Fixed bug #44995 (bcpowmod() fails if scale != 0)

`bc_divmod()` is supposed to do integer division, so we must not apply
a scale factor here.

Fixed bug #75139 (libgd/gd_interpolation.c:1786: suspicious if ?)

We back-port https://github.com/libgd/libgd/commit/dd48286 even though
we cannot come up with a regression test, because the erroneous
condition appears to be impossible to trigger.

We also parenthesize the inner ternary operation to avoid confusion.
