Bug description:  crc32() returns 64-bit number on 64-bit achitectures

Description:
------------
crc32() in PHP returns an integer larger than 2G on a 64-bit platform;
It's documented, and applications rely on it, that it will return a signed
integer from the range [-2G .. 2G]. The major problem with 64-bit crc32()
here is that databases can't store the value in a column declared as
INTEGER, thus braking compatibility.

Reproduce code:
---------------
echo crc32('10780');

Expected result:
----------------
-1171594808

Actual result:
--------------
3123372488
