`struct so_list` was recently renamed to `struct shobj` (in 3fe0dfd1604f
("gdb: rename struct so_list to shobj")). In hindsight, `solib` would
have been a better name. We have solib.c, the implementations in
solib-*.c, many functions with solib in their name, the solib_loaded /
solib_unloaded observables, etc.
Rename shobj to solib.

This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

Commit 8971d2788e7 ("gdb: link so_list using intrusive_list") introduced
a bug in clear_solib. Instead of passing an `so_list *` to
remove_target_sections, it passed an `so_list **`. This was not caught
by the compiler, because remove_target_sections takes a `void *` as the
"owner", so you can pass it any pointer and it won't complain.
This happened because I previously had a patch to change the type of the
disposer parameter to be a reference rather than a pointer, so had to
change `so` to `&so`. When dropping that patch, I forgot to revert this
bit and / or it got re-introduced when handling subsequent merge
conflicts. And I didn't properly retest.
Fix that, but try to make things less error prone. Add a union to
represent the possible owner kinds for a target_section. Trying to pass
a pointer to another type than those will not compile.

Remove this typedef. I think that hiding the real type (std::vector)
behind a typedef just hinders readability.

A subsequent patch changes so_list to be linked using
intrusive_list. Iterating an intrusive_list yields some references to
the list elements. Convert some functions accepting so_list objects to
take references, to make things easier and more natural. Add const
where possible and convenient.

This adds a constructor to target_section, simplifying the code that
creates instances of this.

Because target_section_table only holds a vector, and because it is
used in an "open" way, this patch makes it just be an alias for the
std::vector specialization. This makes the code less wordy. If we do
ever want to add more specialized behavior to this type, it's simple
enough to convert it back to a struct with the few needed methods
implied by this change.

This changes target_section_table to wrap a std::vector. This
simplifies some code, and also enables the simplifications coming in
the subsequent patches.
Note that for solib, I chose to have it use a pointer to a
target_section_table. This is more convoluted than would be ideal,
but I didn't want to convert solib to new/delete as a prerequisite for
this series.

This introduces a new target-section.h file. This makes some of the
later patches in this series a bit cleaner, because new includes of
target.h won't be required. Also I think it's better to have small
header files for each separate data structure.
