Andrew Tridgell a95b429acc AP_Math: added unsigned versions of constrain functions
sometimes it really does matter that we use constrain_uint32() instead
of constrain_int32(). For example, if we have a value like 0xFFFFFFFF
then the result will be very different

we should use unsigned constrain when dealing with unsigned values

Andrew Tridgell 999268cbba AP_Math: fixup matrix algorithms to be in cpp file
this fixes an issue where optimize O2 was forced on any file that
included AP_Math.h. It also fixes the test suite for matrix_alg, and
fixes the type handling to be consistent

Peter Barker 6fe09b6120 AP_Math: move is_valid_octal into adsb
This doesn't ensure the value is octal digits - there's more magic in
it.

Peter Barker 6af0dcfed0 AP_Math: create a constrain_int64
The template system doesn't work across 32/64 bit builds (SITL
vs fmuv4), probably because int is typedef'd to int64
