STB_GNU_UNIQUE is like STB_GLOBAL with extra semantics:
* gold and ld.lld: changed to STB_GLOBAL if --no-gnu-unique is specified
* glibc: unique even with dlopen `RTLD_LOCAL`, implies DF_1_NODELETE
Therefore, I think it makes sense for --weaken-symbol/--weaken-symbols/--weaken
to change STB_GNU_UNIQUE symbols.
binutils 2.39 will have the same behavior: https://sourceware.org/bugzilla/show_bug.cgi?id=28926

With a sufficiently large output buffer, the only failure is Z_MEM_ERROR.
Check it and call the noreturn report_bad_alloc_error if applicable.
resize_for_overwrite may call report_bad_alloc_error as well.
Now that there is no other error type, we can replace the return type with void
and simplify call sites.

Current objcopy implementation has a possibility to add or update sections.
The incoming section is specified as a pair: section name and name of the file
containing section data. The interface does not allow to specify incoming
section as a memory buffer. This patch adds possibility to specify incoming
section as a memory buffer.

libtool uses file names to name members of an static library.
Files, located in different directories and having matching name,
would have the same name inside an archive. This is not a problem
for ld, but may be a problem for ar. This patch renames files
from ObjCopy library to avoid names clashing.
