clib2 Code

- Made ACrypt() compile again.

- Updated the smakefile, so that it includes the new math object files.

- Replaced the (float) casts in strtof() with calls to powf().

- Ported acosh(), acoshf(), asinh(), asinhf(), lgamma(), lgammaf(),
remainder() and remainderf() for C99.

- Ported cosf(), coshf(), sinf(), sinhf(), tanf(), tanhf()
and hypotf() for C99.

- Implemented fmin()/fminf(), fmax()/fmaxf(), fdim()/fdimf() for C99.

- Ported acosf(), asinf(), atan2f(), atanf(), ceilf(), expf(), floorf(),
fmodf(), frexpf(), ldexpf(), log10f(), logbf(), logf(), modff(), powf(), sqrtf(),
scalbn() and scalbnf() for C99.

- Ported cbrt(), cbrtf(), erf(), erff(), erfc(), erfcf(), expm1(),
expm1f(), ilogb(), ilogbf(), log1p() and log1pf() for C99.

- Implemented fmin()/fminf(), fmax()/fmaxf(), fdim()/fdimf() (C99).

- Added skeleton code for acosf(), acosh(), acoshf(), asinf(), asinh(),
asinhf(), atan2f(), atanf(), atanh(), atanhf(), cbrt(), cbrtf(),
ceilf(), cosf(), coshf(), erf(), erfc(), erfcf(), erff(),
exp2(), exp2f(), expf(), expm1(), expm1f(), fdim(), fdimf(),
floorf(), fma(), fmaf(), fmax(), fmaxf(), fmin(), fminf(),
fmodf(), frexpf(), hypotf(), ilogb(), ilogbf(), ldexpf(), lgamma(),
lgammaf(), log10f(), log1p(), log1pf(), log2(), log2f(), logbf(),
logf(), lrint(), lrintf(), lround(), lroundf(), modff(), nearbyint(),
nearbyintf(), powf(), remainder(), remainderf(), remquo(), remquof(), round(),
roundf(), scalbn(), scalbnf(), sinf(), sinhf(), sqrtf(), tanf(),
tanhf(), tgamma(), tgammaf(), trunc() and truncf(), to be filled in
later...

- Added a TODO-list which at this time only covers the missing floating
point arithmetic functions.

- Added NAN, INFINITY, FLT_EVAL_METHOD, float_t and double_t to
<math.h>.
