[Gerd Moellmann]

branch: pkg
commit 0a345a1181c2b90e1af15a44055bd56e7c55cec2
Author: Gerd Möllmann <gerd@gnu.org>
Commit: Gerd Möllmann <gerd@gnu.org>

    Make internals of Lisp_Package visible to Lisp
    
    Done to be able to do as much as possible from Lisp.
    
    * src/lisp.h (Lisp_Package): Rename used_packages to use_list.
    * src/pkg.c: Rename used_packages to use_list.
    (Fpackage_percent_name): (Fpackage_percent_set_name):
    (Fpackage_percent_nicknames):
    (Fpackage_percent_set_nicknames):
    (Fpackage_percent_use_list):
    (Fpackage_percent_set_use_list):
    (Fpackage_percent_shadowing_symbols):
    (Fpackage_percent_set_shadowing_symbols):
    (Fpackage_percent_symbols): New functions for getting and setting
    internals of Lisp_Package.
    (syms_of_pkg): defsubr them.
