Display symbol version when dumping dynrelocs
Both readelf/objdump know how to get symbol version string for dynamic
symbols. This patch extracts this functionality into a separate
function and uses it to add symbol version string to versioned symbol
names when dumping dynamic relocations.

PR binutils/16496
* elf-bfd.h (bfd_elf_get_symbol_version_string): New.
* elf.c (bfd_elf_get_symbol_version_string): New. Extracted
from bfd_elf_print_symbol.
(bfd_elf_print_symbol): Use it.
binutils/
PR binutils/16496
* objdump.c (objdump_print_symname): Call
bfd_elf_get_symbol_version_string to get ELF symbol version
string. Append version string if needed.
* readelf.c (versioned_symbol_info): New enum.
(get_symbol_version_string): New. Extracted from
process_symbol_table.
(dump_relocations): Add a new argument to indicate if dynamic
symbol table is used. Use get_symbol_version_string to get
symbol version string for dynamic symbol. Append version string
if needed.
(process_relocs): Updated dump_relocations call.
(process_symbol_table): Use get_symbol_version_string.
