Fix GC bugs related to uninitialized vectors
Avoid problems if GC occurs while initializing a vector.
Problem with Fdelete reported by Pip Cet in:
https://lists.gnu.org/r/emacs-devel/2020-08/msg00313.html
I looked for similar problems elsewhere and found quite a few.
* src/coding.c (make_subsidiaries):
* src/composite.c (syms_of_composite):
* src/font.c (build_style_table, Ffont_get_glyphs):
* src/nsselect.m (clean_local_selection_data):
* src/nsxwidget.m (js_to_lisp):
* src/syntax.c (init_syntax_once):
* src/window.c (Fcurrent_window_configuration):
* src/xselect.c (selection_data_to_lisp_data)
(clean_local_selection_data):
Use make_nil_vector instead of make_uninit_vector.
* src/fns.c (Fdelete):
* src/xwidget.c (webkit_js_to_lisp):
Use allocate_nil_vector instead of allocate_vector.
* src/search.c (Fnewline_cache_check):
Use make_vector instead of make_uninit_vector.
