Correct time initialization for the case where time is initialized from settings in the .config file. The correct range for month (tm_mon) internally is 0-11, not 1-12 as it is in the .config file.

Revert "Correct a problem in clock_gettime(CLOCK_REALTIME, &time); which is ahead by 1 month of the specified CONFIG_START_MONTH"
...
I don't believe this change is correct in general. Nomralling clock_isleapyear() is called with tm_mon which is in the range of 0-11. That change would be bad for that range. It would make sense for a range of 1-12, but that is not how tm_mon is defined.

libc/time: This commit adds the difftime() function. Since the function returns a double, I have isolated it in a CONFIG_LIBC_DIFFTIME option (It also depends on the toolchain-dependent CONFIG_HAVE_DOUBLE so is not available on tiny platforms).

This commit fixes the following libc/math issues:
...
1) asin[f l]() use Newton’s method to converge on a solution. But Newton’s method converges very slowly (> 500,000 iterations) for values of x close to 1.0; and, in the case of asinl(), sometimes fails to converge (loops forever). The attached patch uses an trig identity for values of x > sqrt(2). The resultant functions converge in no more than 5 iterations, 6 for asinl().
2) The NuttX erf[f l]() functions are based on Chebyshev fitting to a good guess. The problem there’s a bug in the implementation that causes the functions to blow up with x near -3.0. This patch fixes that problem. It should be noted that this method returns the error function erf(x) with fractional error less than 1.2E-07 and that’s fine for the float version erff(), but the same method is used for double and long double version which will yield only slightly better precision. This patch doesn't address the issue of lower precision for erf() and erfl().
3) a faster version of copysignf() for floats is included.
