[issue1530559] struct.pack raises TypeError where it used to convert

Retargeting, now that 2.5 is in security-fix-only mode.

Bob, can you clarify what *should* be happening in 2.6, 2.7, 3.0 and 3.1 
for things like:

struct.pack('L', 2009.1)
struct.pack('L', Decimal('3.14')) 

?

It also seems that 'L' and 'Q behave differently.  For example, with 2.7:

>>> struct.pack('L', 3.1)
sys:1: DeprecationWarning: integer argument expected, got float
'\x03\x00\x00\x00'
>>> struct.pack('Q', 3.1)
'\x03\x00\x00\x00\x00\x00\x00\x00'
