22f3c8b05b 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.

56f8195fe5 - 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.

d8fbd1acef Fix Bug #21523 - number_format could cause a memory allocation for a 
negative memory size in situations where the sprintf implementation of the
host system generated less decimal places than were requested.

Resolved this issue by making number_format examine the string returned
by spprintf and have it pad to the correct number of decimal places.

Added a test-case based on the bug report; the length of decimal places
required to trigger this bug is sprintf implementation dependent; as the
implementation is now using spprintf (provided by PHP), that number is
78 digits (NDIG - 2).

# I played with the idea of enhancing sprintf to do the equivalent, but
# it was too much effort considering that the precision of floats/doubles
# is not good enough to warrant it.

# This fix could do with some QA from someone else to make sure there are
# no memory bounds problems and then MFH it to PHP_4_3
