Log:
Do not include float interfaces when using libsa.
We don't support float in the boot loaders, so don't include
interfaces for float or double in systems headers. In addition, take
the unusual step of spiking double and float to prevent any more
accidental seepage.
This unimproves all the _types.h headers, probably for no benefits for lua.

__types.h headers exist to avoid ifdefs like this. They only define types
in the implementation namespace. Nothing except <math.h> should use
__double_t or __float_t directly. There is only a problem if some option
like -fno-float turns off floating point completely, so that 'float' is
a syntax error.
