Remove tui_win_info::refresh_all
The TUI has two duplicate "re-render this window" methods, "rerender"
and "refresh_all". They differ only slightly in semantics, so I
wanted to see if they could be unified.
After looking into this, I decided that refresh_all was not needed.
There are 4 calls to tui_refresh_all_win (the only caller of this
method):
1. tui_enable. This sets the layout, which renders the windows.
2. tui_cont_sig. Here, I think it's sufficient to simply redraw the
current window contents from the curses backing store, because gdb
state didn't change while it was suspended
3. tui_dispatch_ctrl_char. This is the C-l handler, and here it's
explicitly enough to just refresh the screen (as above).
4. tui_refresh_all_command. This is the command equivalent of C-l.
So, this patch removes this method entirely and simplifies
tui_refresh_all_win.

Fix PR win32/24284: tcp_auto_retry doesn't work in MinGW
This was reported by Bernhard Wodok, along with a patch to fix the
issue. I adjusted the patch a bit, and I'm submitting the patch on
his behalf.
According to Bernhard, the issue can be reproduced by doing:
1. start gdb
2. enter 'target remote :2345'
3. observe that it throws a "connection refused" error immediately
instead of waiting and throwing a timeout error
I.e., I believe it can be reproduced by our current tests, which is
why I'm not proposing any extra tests here (well, I don't use nor have
any Windows system to test this, so...).
The problem happens because, on ser-tcp:wait_for_connect, we call
'gdb_select' passing 0 as its first argument, which, when using MinGW,
ends up using the 'gdb_select' version from mingw-hdep.c, and when the
first argument is 0 this means that WaitForMultipleObjects will be
called with 0 as its first argument as well. According to the MS API
docs, this is forbidden:
https://docs.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-waitformultipleobjects
The proposed fix is simple: we just call Sleep when N == 0 (and when
TIMEOUT is non-NULL), and return 0. It makes sense to me.
Both Bernhard and Paul Carroll confirmed that the fix works. I'm
Cc'ing Bernhard in case you have any questions about the patch.

Well, things have changed since that comment was true and we now can

and cures some of the leaks. Other leaks are caused by
bfd_check_format_matches throwing away bfd tdata before trying a new

gdb/fortran: Implement la_print_typedef for Fortran
Implement an la_print_typedef method for Fortran, this allows 'info
types' to work for Fortran. The implementation is just copied from
ada_print_typedef (with the appropriate changes).
To support the testing of this patch I added a new proc,
fortran_character1, to lib/fortran.exp which returns a regexp to match
a 1-byte character type. The regexp returned is correct for current
versions of gFortran. All of the other regexp are guesses based on
all of the other support procs in lib/fortran.exp, I haven't tested
them myself.

One of our testcases, gdb.python/py-xmethods.exp, contains strings in
the form of "operator\+". This is not recognized by Python, but is
still needed by the testsuite to work properly. The solution is
simple: we just have to make sure these strings are marked as
raw (i.e, r""). This is what this patch does. I took the opportunity
to also convert other strings to raw, which, in two cases, allowed the
removal of an extra backslash.

AArch64: Fix LD crash on weak and undefined TLS symbols. (PR/24602).
This patch fixes a few linker crashes due to TLS code reaching an assert when it
shouldn't.
The first scenario is with weak TLS symbols that remain weak during linking. In
this case the mid-end would not have seen a TLS symbol and so wouldn't have
allocated the TLS section. We currently assert here and the linker crashes with
a not very useful message.
This patch changes this to return the value 0 for the TLS symbol in question
emulating what lld and gold and other BFD targets do. However because weak TLS
is implementation defined and we don't define any behavior for it I also emit a
warning to the user to inform them of such.
Secondly when a strong TLS reference is undefined. The linker crashes even after
it correctly reported that there is an undefined reference. This changes it so
that it gracefully exits and reports a useful error.

ARM CMSE symbols
This patch removes use of st_target_internal to cache the result of
comparing symbol names against CMSE_PREFIX. The problem with setting
a bit in st_target_internal in swap_symbol_in is that calling
bfd_elf_sym_name from swap_symbol_in requires symtab_hdr, and you
don't know for sure whether swap_symbol_in is operating on dynsyms
(and thus elf_tdata (abfd)->dynsymtab_hdr should be used) or on the
normal symtab (thus elf_tdata (abfd)->symtab_hdr). You can make an
educated guess based on abfd->flags & DYNAMIC but that relies on
knowing a lot about calls to bfd_elf_get_elf_syms, and is fragile in
the face of possible future changes.
