Subject: Switching some globals to lexical and changing some names.

* arith.c (arith-init): Changing *flo-...* from special to
lexical, and adding un-earmuffed variants. The earmuffed
versions are obsolescent.
Adding %pi% and %e% global lexicals. Earmuffed versions are
also made global lexical, and obsolescent.

* eval.c (lookup_global_var, lookup_global_var_l): New functions.
(lookup_var): Uses lookup_global_var.
(reg_varl): New function.
(reg_var): Uses reg_var.
(eval_init): Register global lexicals user-package, system-package
and keyword-package. Old symbols with earmuffs are obsoleted,
and also turned into global lexicals.
(top-vb, top-fb): Changed to lexical.

* eval.h (lookup_global_var, lookup_global_var_l, reg_varl):
Declared.

* genvim.txr: Scan ver.tl so that the lib-version variable
is included. Extract reg_varl calls.

* glob.c (glob_init): glob-err and other variables made lexical.

* lib.c (get_user_package, get_system_package, get_keyword_package):
Use lookup_global_var_l to avoid searching dynamic scope for
lexicals which cannot be dynamically rebound.

* share/txr/stdlib/ver.tl (lib-version): New global lexical variable.
(*lib-version*): Turned lexical. Obsolescent.

* signal.c (sig-init): sig-* variables turned lexical.

* sysif.c (sysif-init): s-*, poll-* and w-* variables turned lexical.

* syslog.c (syslog-init): log-* variables turned lexical.

* txr.c (sysroot-init): stdlib and *txr-version* variables turned
lexical. txr-version variable added, and *txr-version* is
obsolescent.
(txr-main): self-path variable added. *self-path* turns lexical
and is obsolescent.

* txr.1: Documentation updated. Lexical variables not referred
to as special. Special variables referred to as special.
