Support makeinfo versions with 3 parts and simplify computation

Test versions of makeinfo have version numbers like 6.8.90. Update
configure to handle this so that we get a version of 6.8.90 instead of
8.90, which would be wrong.

We also simplify the tests for the version number by creating a
numerical value by multiply the major version by 100 and adding the
minor version. This assumes that the minor version is never larger
than 99. Then we can just compare integers. Thus 5.0 is version 500,
and that's easy to compare against 5.1 (version 501).

Handle lisp args better for category program

The current code does
```
$lispprog $lispargs
```

But when lispargs is complicated, this doesn't actually pass the
desired lispargs correctly. For example for cmucl, we want to do
```
lispargs="-noinit -nositeinit -eval '(setf *gc-verbose* nil *default-external-format* :utf8)' -eval '(set-system-external-format :utf8 :utf8)' -load $catprogname -eval '(quit)'"
```

But the actual args are parsed in an unexpected way. This can be tested
via this simple program
```
#include <stdio.h>
int
main(int argc, char **argv)
{
        int i;

        for (i = 0; i < argc; i++) printf("argv[%d]='%s'\n", i, argv[i]);
        return 0;
}
```

Then
```
$ lispargs="-noinit -nositeinit -eval '(setf *gc-verbose* nil *default-external-format* :utf8)' -eval '(set-system-external-format :utf8 :utf8)' -load $catprogname -eval '(quit)'"
$ ./args $lispargs
argv[0]='./args'
argv[1]='-noinit'
argv[2]='-nositeinit'
argv[3]='-eval'
argv[4]=''(setf'
argv[5]='*gc-verbose*'
argv[6]='nil'
argv[7]='*default-external-format*'
argv[8]=':utf8)''
argv[9]='-eval'
argv[10]=''(set-system-external-format'
argv[11]=':utf8'
argv[12]=':utf8)''
argv[13]='-load'
argv[14]='-eval'
argv[15]=''(quit)''

```
Note that the `(setf *gc-verbose* nil)` is broken up into 3 separate
args which is not what we want. It should be just one arg, which is
the arg to `-eval`. What we really want is:
```
argv[0]='./args'
argv[1]='-noinit'
argv[2]='-nositeinit'
argv[3]='-eval'
argv[4]='(setf *gc-verbose* nil *default-external-format* :utf8)'
argv[5]='-eval'
argv[6]='(set-system-external-format :utf8 :utf8)'
argv[7]='-load'
argv[8]='-eval'
argv[9]='(quit)'
```

To fix this, we add a `runlisp` function to run the lisp with the
desired args. And instead of putting all the args into lispargs, we
just call runlisp after deciding which lisp is being used and just
append the desired args to the runlisp command.

Update makeinfo version test to work with MacOS

The main problem was that on MacOS, expr didn't like the regexp
operator "+" in, say, "[0=9]+". This is easily fixed by using the
equivalent "[0-9][0-9]*".

We also added some more checks to make sure that makeinfo_version is
not empty and that makeinfo_major and makeinfo_minor are not empty
either. If any of these are empty, produce an error message.

Tested this on MacOS and verified that the warning messages are
produced (by using a faulty regexp for expr).

Fix #3967: elliptic_e(5*%pi/4,1) incorrect

elliptic_e(5*%pi/4,1) was returning 2-1/sqrt(2), but
elliptic_e(5*%pi/4,1),numer returned 2.707... or basically
2+1/sqrt(2).

This happens because we were simplifying elliptic_e(5*%pi/4,1) to
sin(5*%pi/4) = -1/sqrt(2). But we need to reduce the arg 5*%pi/4 by
%pi so we get sin(%pi/4) = 1/sqrt(2).

Add a test for this and that the symbolic and numerical values are
consistent.

Also needed to update the test for elliptic_e(x,1) to include the
reduction of the arg for the sin part.

Experiment to use reader macro to embed maxima expressions in lisp

We implement a reader macro (from Stavros) to allow embedding Maxima
expressions in Lisp code to make it easier to write.

So we can write

  (with-maxima-expr ""sin(?phi) + 2*round(?phi/%pi)*elliptic_ec(?m)")

instead of

(add (ftake '%sin phi)
     (mul 2
   (mul (ftake '%round (div phi '$%pi))
        (ftake '%elliptic_ec m))))

We add this macro to various places in ellipt.lisp for testing.

However some tests fail and this needs to be fixed before we can
generally allow this feature.

translator: fix MQAPPLY array assignments when translate_fast_arrays:true

This is a very old Maxima bug that was not present in Macsyma.

In the translate_fast_arrays case, MASET did not handle the MQAPPLY
case. A lisp error would occur at runtime when attempting the
assignment.

(%i1) foo () := (a : make_array ('fixnum, 5), b() := a, b()[1] : 5)$

(%i2) translate_fast_arrays : true$

(%i3) translate (foo)$

(%i4) foo ();
<lisp error>

Now a special case for MQAPPLY has been added to MASET (similar to
the special case that exists in MAREF).

No problems with the test suite or share test suite. A new test has
been added to rtest_translator.

Print correct exponent if bfloat rounds up

As reported on the maxima list
(https://sourceforge.net/p/maxima/mailman/message/37353663/), some bfloats
aren't printed with the correct exponent if the number needs to be
rounded up and the rounding causes the exponent to change.

The solution here is to look at the number of digits that would be
printed. If it's greater than effective-printprec, then we must have
had to round the number up to the next power of 10, but we didn't
account for that in the exponent. So, when the number of digits is
not the expected length, increase the exponent by the number of excess
digits. We also need to remove the excess digits from the number so
that the printed result has the right number of digits (if bftrunc is
false).

A couple of simple tests are added to rtest3.mac.

Comment out definitions of cons-exp

Comment out cons-exp but leave it for a bit until we're sure all uses
are gone. `git grep '(cons-exp'` shows that there are no longer any
occurrences.

Replace POW with POWER and remove POW.

We should use POWER everywhere instead of POW, since POW just
basically expands to POWER.

Testsuite runs fine with this change.

Need reversealias property for grind and plot labels

Grind and plot needs the reversealias property to be able to print out
the right thing. Without this, the result is the verb (%) form. We
really want the noun (%) form. This happens in msize-atom which will
strip the dollar sign off the noun form to produce the desired result.

Also added some comments on what the properties are need for.

Remove old simp functions

These were all replaced by def-simplifier, so we can remove the old
versions now.

Do arg count check first

The arg count check should be done right away instead of later.
There's no point in doing a simpcheck on args if the number of args is
incorrect.
