- More common filename accross the PHP repository
- Additionally, this patch replaces some legacy form feed (FF or ^L)
characters (for printers) to LF (\n) newline character.
The `<assert.h>` header file is part of the standard C89 headers [1] and
on older systems there needed to be also a manual check if header is
present.
Since PHP requires at least C89 manual check and the `HAVE_ASSERT_H`
symbol defined by Autoconf in configure.ac can be both removed [2].
This patch also removes unused <assert.h> includes where c files don't
use the `assert()` macro.

We change `bcmul()` and `bcpow()` so that the result has exactly the
requested scale (i.e. decimal places) to make them consistent with the
other BCMath functions. This also changes our stance regarding bug
#52748, which had been classified as documentation problem.
We do not manipulate the numbers themselves (anymore), but rather
introduce `bc_num2str_ex()` which accepts a scale parameter that
overrides the scale of the number by omitting extraneous decimals and
adding zeros, respectively. This also allows us to get rid of
`split_bc_num()`, which fixes bug #75164 as well.
