b4194dfd55 Compute the exponential of x for Intel 80-bit format and IEEE 128-bit 
format.  These implementations are based on

PTP Tang, "Table-driven implementation of the exponential function
in IEEE floating-point arithmetic," ACM Trans. Math. Soft., 15,
144-157 (1989).

quotation. Also make sure we have the same amount of columns in each row as
the number of columns we specify in the head arguments.

2a41d7e805 It's no longer accurate to say that math.h "constitute[s] the C math 
library," since complex.h, tgmath.h, and fenv.h are also part of the
math library.  Replace the outdated sentence with some references to
the other parts.

c519d48b44 Implement the long double version for the cube root function, cbrtl. 
The algorithm uses Newton's iterations with a crude estimate of the
cube root to converge to a result.

0ec5232d0c The logb() functions are not just ieee754 "test" functions, but are 
standard in C99 and POSIX.1-2001+.  They are also not deprecated, since
apart from being standard they can handle special args slightly better
than the ilogb() functions.

Move their documentation to ilogb.3.  Try to use consistent and improved
wording for both sets of functions.  All of ieee854, C99 and POSIX
have better wording and more details for special args.

Add history for the logb() functions and ilogbl().  Fix history for
ilogb().
