Re-formats the BCmath extension to have consistent formatting.
Mostly, it adds the spaces in calculations to have them more readable.
Also:
- removes unused headers
- removes few variables which are used only once in the code

* ext/bcmath: coding style: use indentation
And add braces to block statements, as the current code was pretty much unreadable with how inconsistent it was.
* ext/bcmath: Remove some useless header inclusions
* ext/bcmath: Use standard C99 bool type instead of char
* ext/bcmath: Include specific headers instead of config.h
* Restructure definitions to reduce header inclusions
* Use size_t as a more appropriate type
* Remove unused variable full_scale
* Refactor bc_raisemod() to get rid of Zend dependencies
This separates the concerns of throwing exceptions back into the PHP_FUNCTION instead of being the responsibility of the library
* Refactor bc_raise() to get rid of Zend dependencies
This separates the concerns of throwing exceptions back into the PHP_FUNCTION instead of being the responsibility of the library
* Refactor bc_divmod() and bc_modulo() to return bool
Return false on division by 0 attempt instead of -1 and true on success instead of 0
* Refactor bc_divide() to return bool
Return false on division by 0 attempt instead of -1 and true on success instead of 0
- 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.
This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.
According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

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.

Instead of writing warning messages to `stderr`, we employ PHP's error
handling to raise `E_WARNING` even for the single case where
`bc_rt_error()` has been called, since that did not actually error out.
We choose to call `php_error_docref()` directly in libbcmath, since
there is no upstream, and since other PHP core functionality is already
used in our bundled libbcmath. Accordingly, we remove `rt.c` so it will
not be accidentally used in the future.
Besides adapting a few existing tests, we add new tests so that the
warnings are tested at least once. We also get rid of the Windows
specific tests, since the warning behavior is now supposed to be
platform-agnostic.
