binutils security and bug fix update

[2.30-73.0.1]

• Forward-port of Oracle patches from 2.30-68.0.2.
• Reviewed-by: Elena Zannoni
  [2.30-68.0.2]
• Backport the non-cycle-detecting-capable deduplicating CTF linker
• Backport a fix for an upstream hashtab crash (no upstream bug number),
  triggered by the above.
• Fix deduplication of ambiguously-named types in CTF.
• CTF types without names are not ambiguously-named.
• Stop the CTF_LINK_EMPTY_CU_MAPPINGS flag crashing.
• Only emit ambiguous types as hidden if they are named and there is already
  a type with that name.
• Make sure completely empty dicts get their header written out properly
• Do not fail if adding anonymous struct/union members to structs/unions that
  already contain other anonymous members at a different offset
• Correctly look up pointers to non-root-visible structures
• Emit error messages in dumping into the dump stream
• Do not abort early on dump-time errors
• Elide likely duplicates (same name, same kind) within a single TU (cross-
  TU duplicate/ambiguous-type detection works as before).
• Fix linking of the CTF variable section
• Fix spurious conflicts of variables (also affects the nondeduplicating linker)
• Defend against CUs without names
• When linking only a single input file, set the output CTF CU name to the
  name of the input
• Support cv-qualified bitfields
• Fix off-by-one error in SHA-1 sizing

• Allow the BFD library to handle the copying of files containing secondary reloc sections. (#1801879)
  [2.30-68.0.1]
• Ensure 8-byte alignment for AArch64 stubs.

  libctf-nonbfd.so. The linker does not yet deduplicate the CTF type section.
• Backport of fix for upstream bug 23919, required by above
• [Orabug: 30102938] [Orabug: 30102941]
