Patch to fix some strict warnings

[GoogleCodeExporter]

This patch fixes some warnings if you have a lot of warnings turned on when
developing on the iphone in objective-c.

----

Description of fixes:

Rename of local variable 'index' to 'idx' to prevent a warning about the
variable masking one in global scope.

Change use of 'fabsf' to 'cpfabs' (presumably as intended), to fix warning
about implicit conversion to 32-bit type from 64-bit type when cpFloat is
double.

Change return value of segValueOnAxis from 'float' to 'cpFloat' (presumably
as intended), to fix warning about implicit conversion to 32-bits.

Added prototypes for some internal/private functions to fix warnings about
no prototype for these functions.

Made conversion from cpFloat to int for l, r, b, t in space hash functions
explicit, to prevent warning about implicit conversion to 32-bit type.

Renamed local variable 'id' to 'hashid' in some hash functions, to prevent
warning about the local variable masking objective-c's 'id' type.

I updated this patch, see this new version attached which contains the same 
changes
as the previous version, plus the following:

----

Added easy #if to change between cpFloat being double or single precision.

Cast some constants to cpFloat, to prevent implicit conversion warnings when 
cpFloat
is set to single precision.
