* rangetab.h:
* rangetab.h (struct range_table_entry):
* rangetab.h (struct Lisp_Range_Table):
* rangetab.h (rangetab_gap_array_at):
* symsinit.h:
Rename dynarr.c to array.c. Move gap array from extents.c to array.c.
Extract dynarr, gap array and stack-like malloc into new file array.h.
Rename GAP_ARRAY_NUM_ELS -> gap_array_length(). Add gap_array_at(),
gap_array_atp().
Rewrite range table code to use gap arrays. Make put_range_table()
smarter so that its operation is O(log n) for adding a localized
range.
* gc.c (lispdesc_block_size_1):
Don't ABORT() when two elements are located at the same place.
This will happen with a size-0 gap array -- both parts of the array
(before and after gap) are in the same place.
