Fixed bug #42294 (Unified solution for round() based on C99 round)
...
[DOC] New implementation of round() to work-around inconsistencies for win32
and 64 bit platforms.
This solution is very roughly based on BSD's implmentation of round(), which
itself is an implementation of C99 standard. We take the absolute value of number
we want to round time the 10 to the power of the number of decimal spaces we are
rounding to. The resulting value is rounded up and the pre-rounded value is
subtracted from it. If the difference is greater then 0.5000000001 we round up,
otherwise we round down.

- Nuke empty_string. It is a reminanent from the time where RETURN_FALSE()
...
used to return "" and not bool(false). It's not worth keeping it because
STR_FREE() and zval_dtor() always have to check for it and it slows down
the general case. In addition, it seems that empty_string has been abused
quite a lot, and was used not only for setting zval's but generally in
PHP code instead of "", which wasn't the intention. Last but not least,
nuking empty_string should improve stability as I doubt every place
correctly checked if they are not mistakenly erealloc()'ing it or
calling efree() on it.
NOTE: Some code is probably broken. Each extension maintainer should
check and see that my changes are OK. Also, I haven't had time to touch
PECL yet. Will try and do it tomorrow.
