[PATCH] kill a few compiler warnings in 5_1 branch

Hi all,

There are 174 compiler warnings in the PHP_5_1 branch under MSVC at present,
so this is an attempt to get the number down a bit (like, by around 20%) by
getting rid of the simpler ones.

I've separated out those I'm really not sure about
(warnings_php5_unsure.txt), the rest are all simple casts. The test suite
shows no changes if all three of these patches are applied, but obviously
array.c and string.c are a bit close to the bone for 'probably works' so
please use judgement if applying!

Note: nearly half the remaining compiler warnings are due to type
conversions in ext/date, which is only to be expected of a new extension, so
it's not quite as bad as it looks...

Cheers,

Steph
