Fix #4121: atan2(0, <nz>) doesn't simplify

atan2(0,x), when sign(x) is nz should simplify to %pi. The code was
checking for sign(x) being neg, not nz. Modify the code to look for
both, just like how we simplify atan2(0,x) when sign(x) is pos, or pz.

Add test for this. We also fix a typo where the start of comment was
inadvertently left off.

Assert integrand returns a real value for quadpack routines

Because the quadpack routines call coerce-float-fun to be able to
evaluate the integrand, the realpart is returned by default. Instead,
we bind `*plot-realpart*` to nil so that evaluation can return complex
numbers. Then modify float-integrand-or-lose to check for floats
since it was previously checking for cl:number.

Finally to make this all work, declaim `*plot-realpart*` to be special
because we compile plot.lisp (that defines it) **after** compiling
quadpack.lisp. Reordering causes other problems.

Greedier logic for autodetecting which lisps to compile with

If the user hasn't specified a lisp to compile maxima with and
we already have autodetected that more than one suitable lisp
is installed on the system there is no good reason to just pick
one lisp by chance and to compile using that one.
Instead we should compiling using all available lisps in that
case.

If the user has explicitely chosen which lisps to compile on
that choice is respected and no additional lisps are used -
just like ./configure did until now.

One side-effekt this change has is that it makes things easier
for packagers as it means that even if maxima is compiled with
more than one lisp no special ./configure args are needed.

Fix incorrect --no-init that wasn't working

--no-noinit is supposed to disable loading of the init files.
However, it wasn't working because the user init files were loaded
before the command-line args were processed. Therefore, load the user
init files after processing the command-line args.

Also, print out the init files that are loaded. This is useful to see
that we've loaded the user init files (and where). Also useful if we
expected an init file to be loaded and wasn't or the wrong init file
was loaded.

This includes any files loaded via the -p option. This is useful to
know exactly which file was loaded since the -p option uses
file_search to find the file to load.

Add new file, global-var-init, for initializing globals.

Instead of initializing global vars in `initialize-runtime-globals`,
add a new file, "global-var-init.lisp" to initialize these. Some
variables need special handling because we can't initialize them in
globals.lisp because the necessary functions aren't available when
globals.lisp is compiled. Hence, have globals-var-init do the
initialization. Move the initializations from
`initialize-runtime-globals` to global-var-init.lisp.

This request came from a private communication for a user (unixlisp)
who wanted to be able to load maxima without running `cl-user::run`.
This is not a use-case I care about, but moving the initialization to
a separate file works for this use-case as well as the normal usage of
maxima with a repl.

Attempt to be careful about computation of height and depth in display code.
Calculation is working correctly from what I can tell, and pretty printer
output appears to be correct, but box(...) has spurious empty lines at the
bottom of the box. This is due to special variables for height and depth
being updated incorrectly. Given that those variables are used widely in
the display code, it seems too difficult at this point to straighten it out.

This commit addresses SF bug #4105: "Lisp error displaying a long string and subscripted variables"
The bug mentioned in that bug report is indeed fixed by this commit;
maybe I should let that be enough, without trying to fix the other stuff
about height and depth in box. I will have to think about it.
