fdbf53d7e8 add vercos(), avercos(), covercos(), acovercos()
Improved trig help files.

Added new vercos(x, [,eps]) for versed cosine and covercos(x, [,eps])
for inverse versed cosine.

Added new avercos(x, [,eps]) for inverse versed cosine and acovercos(x, [,eps])
for inverse coversed cosine.

3abedd6713 fix aversin() and acoversin()
In cases where the real value to the inverse versed sine and the
inverse coversed sine function produces a complex value, the
conversion from real to complex was incorrect.

Added c_to_q(COMPLEX *c, bool cfree) to make is easier to convert
a COMPLEX value that is real (imag part is 0) into a NUMBER and
optionally free the COMPLEX value.

The func.c code now uses c_to_q().

NOTE: There is a XXX bug marked in the f_aversin() and f_acoversin()
that still needs to be fixed.

86f1d9e029 add new aversin and acoversin builtin functions.
Added new aversin(x, [,eps]) for inverse versed sine and acoversin(x, [,eps])
for inverse coversed sine.

Improved trig function help files to reference use of complex arguments
that while supported were not documented.

Removed old Makefile testing rules for make dbx and make gdb.

Improved "make run" to execute calccalc using shared libraries
from the local directory, and with reading of the startup scripts
disabled.

Changed "make prep" to perform various tests that are used to
help verify that calc is ready for a release.

Added Makefile testing rule testfuncsort to check for the sort
of the builtin function list.  Changed the order that builtin
functions are listed by "show builtin" and the help/builtin to
match the sorting of "LANG=C LC_ALL=C sort -d -u".

20ce75a06d move versin() and coversin() code
Moved versin() and coversin() to bottom of functions in func.c
(however the builtin function list remains sorted).

Created a historical trig functions section for cmath.h and qmath.h.

Moved cal/test3500.cal to cal/test9300.cal to make room
for future trip tests going from test 3427 thru 3599.

7398fbb2e9 rename vercos to coversin
The code to compute 1 - sin(x) belongs to coversin, not vercos.

b0a48a2b70 add new versin and vercos builtin functions
Added new versin(x, [,eps]) for versed sine and vercos(x, [,eps])
for versed cosine.

Updated trig help files.

4e5fcc8812 add log2(x [,eps]) builtin function
Added log2(x [,eps]) builtin function.  When x is an integer
power of 2, log2(x) will return an integer, otherwise it will
return the equivalent of ln(x)/ln(2).

3c18e6e25b changed C source to use C booleans with backward compatibility
Fix "Under source code control" date for new version.h file.

Sorted the order of symbols printed by "make env".

Test if <stdbool.h> exists and set HAVE_STDBOOL_H accordingly
in have_stdbool.h.  Added HAVE_STDBOOL_H to allow one to force
this value.

Added "bool.h" include file to support use of boolean symbols,
true and false for pre-c99 C compilers.  The "bool.h" include
file defines TRUE as true, FALSE as false, and BOOL as bool:
for backward compatibility.

The sign in a ZVALUE is now of type SIGN, whcih is either
SB32 when CALC2_COMPAT is defined, or a bool.

Replaced in C source, TRUE with true, FALSE with false, and
BOOL with bool.

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!
