gas dwarf2dbg.c tidy
Make it a little more obvious that remap_debug_filename returns an
allocated string (that should be freed) by returning a char * rather
than const char *. Free a few missed cases in dwarf2dbg.c, and free
other memory allocated in dwarf2dbg.c. Also remove static
initialisation of variables and initialise in dwarf2_init instead,
in order to ensure gas state is saner for oss-fuzz.
* remap.c (remap_debug_filename): Remove const from return.
* as.h (remap_debug_filename): Update prototype.
* config/obj-elf.c (obj_elf_ident): Simplify free of
remap_debug_filename output.
* stabs.c (stabs_generate_asm_file): Likewise.
* dwarf2dbg.c (dirs, dirs_in_use, dirs_allocated, current): Don't
initialise statically..
(dwarf2_init): ..do so here, along with most other static vars.
(assign_file_to_slot): Don't set files_allocated until we
succeed in allocating memory.
(purge_generated_debug): Add bool param, free more stuff if true.
(dwarf2_directive_filename): Adjust purge_generated_debug call.
(process_entries): Don't free line_entry here..
(dwarf2_cleanup): ..do so here instead, new function.
(dwarf2_finish): Call dwarf2_cleanup. When chaining together
subseg line entries, unhook entries from old subseg list.
(dwarf2_directive_loc): Free remap_debug_filename string.
(out_dir_and_file_list): Likewise.
(out_debug_str): Likewise.
