c78a893862 add exterior trigonometric functions
Added the following new trigonometric functions:

    exsec(x [,eps])		exterior trigonometric secant
    aexsec(x [,eps])		inverse exterior trigonometric secant
    excsc(x [,eps])		exterior trigonometric cosecant
    aexcsc(x [,eps])		inverse exterior trigonometric cosecant

Added to test 95dd and test9500.trigeq.cal to the calc regression test
suite to perform extensive test of trigonometric functions.

Added to test 34dd, some if the missing inverse trigonometric tests.

ab95e47c0a fix and improve trigonometric help files
The trigonometric file files have had several bug fixed.

The EXAMPLE sections of trigonometric file have
been made consistent.

Added these new help files in anticipation of
the code for these new (i.e., to be written) builtin functions:

    hacovercos hacoversin havercos haversin
    ahacovercos ahacoversin ahavercos ahaversin

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".
