Fix GH-12143: Optimize round 
Fixed an error in the result due to "pre-rounding" of the round function.

"Pre-rounding" has been abolished and the method of comparing numbers has
been changed.

Closes GH-12268.

abs: Make value == ZEND_LONG_MIN an unexpected branch 
As suggested in GH-12286. This results in slightly better assembly in clang,
because the expected case will be handled by a forward jump that is not taken.

Unify type juggling in math.c (#12286) 
- Consistently use a `switch()` with `EMPTY_SWITCH_DEFAULT_CASE();`
- Consistently use `zval_get_double()` for multi-type / non-double zvals
  instead of casting manually.

Reimplement php_round_helper() using modf() (#12220) 
This change makes the implementation much easier to understand, by explicitly
handling the various cases.

It fixes rounding for `0.49999999999999994`, because no loss of precision
happens by adding / subtracing `0.5` before turning the result into an integral
float. Instead the fractional parts are explicitly compared.

see GH-12143 (this fixes one of the reported cases)
Closes GH-12159 which was an alternative attempt to fix the rounding issue for
`0.49999999999999994`

Update http->https in license (#6945) 
1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.
4. fixed indentation in some files before |

e35bdb4912 Add fdiv() function 
The fdiv() function is part of the fmod() / intdiv() family. It
implements a floating-point division with IEEE-754 semantics.
That is, division by zero is considered well-defined and does not
trigger any kind of diagnostic. Instead one of INF, -INF or NAN
will be returned, depending on the case.

This is in preparation for throwing DivisionByZeroError from the
standard division operator.
