Alexey Frunze e5c844eff2 Floating point improvements
- Smaller C: fix a bug in __func__ introduced with
  float-related changes
- make *printf() print floats greater than 1e25
- make *printf() print the plus sign when the format
  includes "+", e.g. printf("%+f\n", 1.0);
- clean up and complete prototypes in <math.h>
- remove non-standard HUGE and LOGHUGE from <math.h>
- add HUGE_VAL to <math.h>
- express some hard-coded limits in terms of constants
  from <float.h>
- uncomment prototypes of several floating point
  conversion functions in <stdlib.h> for Smaller C
