libc/math/lib_asin.c: The function did not convert for some input values.  Asin did not convert for values which do not belong to the domain of the function. But aside of that the function also did not convert for sine allowed values.  I achieved a conversion of the function by reducing the DBL_EPSION and by checking if the input value is in the domain of the function. This is a fix for the problem but the function should always terminate after a given number of iterations.  From Stefan Kolb.
