asan: readelf: memory leaks
This tidies some code used by readelf, hopefully fixing some
intermittent oss-fuzz bug reports that likely could only be reproduced
by feeding readelf two or more object files on the command line. The
second and subsequent file may see non-zero state in .bss variables,
and non-initial values in .data variables. This patch fixes some of
those, and moves some .data variables to .rodata.
* dwarf.c (frame_display_row): Do without static variable "sloc".
(cu_tu_indexes_read): Move to file scope.
(free_debug_memory): Reset it here, along with level_type_signed.
Free and clear a number of other static variables.
* readelf.c (arm_attr_public_tag <table>): Constify, updating..
(arm_attr_tag_*): ..all these uses.
(process_mips_specific): Free "rels" on error path.
