* Rename .ctors to .init_array and change sh_type to SHT_INIT_ARRAY (GNU objcopy
detects the special name but we don't).

[llvm-objcopy][ELF] Allow --set-section-flags src=... and --rename-section src=tst
* GNU objcopy supports --set-section-flags src=... --rename-section src=tst and --set-section-flags runs first.
* GNU objcopy processes --update-section before --rename-section.
To match the two behaviors, postpone --rename-section and allow its use together
with --set-section-flags.
As a side effect, --rename-section=.foo1=.foo2 --add-section=.foo1=/dev/null
leads to .foo2 while GNU objcopy surprisingly produces .foo1 (so
--set-section-flags --add-section --rename-section do not form a total order).
I think the deviation is fine as a total order makes more sense.
Rename set-section-flags-and-rename.test to
set-section-attr-and-rename.test and additionally test --set-section-alignment

[llvm-objcopy] Remove support for legacy .zdebug sections
clang 14 removed -gz=zlib-gnu support and ld.lld removed linker input support
for zlib-gnu in D126793. Now let's remove zlib-gnu from llvm-objcopy.
* .zdebug* sections are no longer recognized as debug sections. --strip* don't remove them.
They are copied like other opaque sections
* --decompress-debug-sections does not uncompress .zdebug* sections
* --compress-debug-sections=zlib-gnu is not supported
It is very rare but in case a user has object files using .zdebug . They can use
llvm-objcopy<15 or GNU objcopy for uncompression.
--compress-debug-sections=zlib-gnu is unlikely ever used by anyone, so I do not
add a custom diagnostic.

[llvm-objcopy] --weaken-symbol/--weaken: weaken STB_GNU_UNIQUE symbols
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

[objcopy] Refactor CommonConfig to add posibility to specify added/updated sections as MemoryBuffer.
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.

[objcopy][NFC] Rename files to avoid clashing of archive members.
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.
