Drop superfluous LONG_MAX/LONG_MIN fallback definitions (GH-15667)
...
Both macros are supposed to be defined in limits.h (C99) and as such it
is superfluous to provide fallback definitions. Even worse, because
these fallback definitions didn't cater to LP64, ILP64 and SILP64 data
models (and maybe some rather uncommon ones), but just assumed ILP32,
they are confusing.

[RFC] Support object types in BCMath ( #13741 )
...
Added BcMath\Number class. It is an immutable object, has methods that are
equivalent to existing BCMath calculation functions, and can also be calculated
using operators.
The existing BCMath function returned a string for each calculation, but this
class returns an object.

Added scale to bc_compare argument ( #14802 )
...
In the original specification, the scale of bc_num was directly changed
and compared.
This becomes a problem when objects are supported, so we will modify it
to compare without changing bc_num.

ext/bcmath: Minor fixes to bcmul() ( #14564 )
...
The original calculation method for prod_arr_size allowed for some error,
which could have increased the number of simple loops without byte tricks
at the end of the calculation when converting to bc_num.
The new method calculates the size accurately, so the number of loops does
not increase unnecessarily.
