db582d6e34 add config("triground") to trigonometric function rounding 
The config("triground") controls rounding for the following
trigonometric and hyperbolic functions:

    sin, cos, tan, cot, sec, csc
    asin, acos, atan, acot, asec, acsc
    versin, coversin, vercos, covercos
    aversin, acoversin, avercos, acovercos
    haversin, hacoversin, havercos, hacovercos
    ahaversin, hacoversin, havercos, ahacovercos
    exsec, aexsec, excsc, aexcsc
    crd, acrd
    cas, cis
    sinh, cosh, tanh, coth, sech, csch
    asinh, acosh, atanh, acoth, asech, acsch

In addition to taking a complex root (such as via the power
function on a complex value), "triground" is used for:

    exp, polar

For the above mentioned functions, the rounding mode used to
round the result to the nearest epsilon value is controlled by,
and defaults to:

    config("triground", 24)

As with other config options, the call returns the previous mode,
without a 2nd argument, returns the current mode without changing it:

    config("triground")

Improved "SEE ALSO" for the hyperbolic function help files.

1c839dfede add logn and error checking for invalue eps and epsilon values 
Add new logn(x, n [,eps]) builtin to compute logarithms to base n.

Verify that eps arguments (error tolerance arguments that override
the default epsilon value) to builtin functions have proper values.
Previously the eps argument had little to no value checks for
many builtin functions.

Document in help files for builtin functions that take eps arguments,
the LIMIT range for such eps values.

a31078bbec Remove all RCS @(#) lines and RCS strings 
Some folks might think: “you still use RCS”?!?  And we will say,
hey, at least we switched from SCCS to RCS back in … I think it was
around 1994 ... at least we are keeping up! :-) :-) :-)

Logs say that SCCS version 18 became RCS version 19 on 1994 March 18.

RCS served us well.  But now it is time to move on.   And so we are
switching to git.

Calc releases produce a lot of file changes.  In the 125 releases
of calc since 1996, when I started managing calc releases, there
have been 15473 file mods!
