gdb: make use add_setshow_prefix_cmd in gnu-nat.c
In gnu-nat.c we currently implement some set/show prefix commands
"manually", that is, we call add_prefix_cmd, and assign a set and show
function to each prefix command.
These set/show functions print an error indicating that the user
didn't type a complete command.
If we instead switch to using add_setshow_prefix_cmd then we can
delete the set/show functions, GDB provides some default functions,
which give a nice help style summary that lists all of the available
sub-commands, along with a one line summary of what each does.
Though this clearly changes the existing behaviour, I think this
change is acceptable as the new behaviour is more inline with other
set/show prefix commands, and the new behaviour is more informative.
This change will conflict with Tom's change here:
https://sourceware.org/pipermail/gdb-patches/2022-January/184724.html
Where Tom changes the set/show functions that I delete. My suggestion
is that the set/show functions still be deleted even after Tom's
patch (or instead of Tom's patch).
For testing I've build GDB on GNU/Hurd, and manually tested these
functions. I did a grep over the testsuite, and don't believe the
existing error messages are being checked for in any tests.

Fix pager regression
The patch to fix paging with redirection caused a regression in the
internal AdaCore test suite. The problem occurs when running an MI
command from the CLI using interpreter-exec, when paging is enabled.
This scenario isn't covered by the current test suite, so this patch
includes a new test.
The problem is that, in this situation, MI does:
fputs_unfiltered (strcmp (context->command, "target-select") == 0
? "^connected" : "^done", mi->raw_stdout);
Here raw_stdout is a stdio_file wrapping stdout, so the pager thinks
that it is ok to buffer the output. However, in this setup, it isn't
ok, and flushing the wrap buffer doesn't really work properly. Also,
MI next does:
mi_out_put (uiout, mi->raw_stdout);
... but this uses ui_file::write, which also doesn't flush the wrap
buffer.
I think all this will be fixed by the pager rewrite series I'm working
on. However, in the meantime, adding the old gdb_stdout check back to
the pager fixes this problem.

elf: Set p_align to the minimum page size if possible
Currently, on 32-bit and 64-bit ARM, it seems that ld generates p_align
values of 0x10000 even if no section alignment is greater than 0x1000.
The issue is more general and probably affects other targets with multiple
page sizes.
While file layout absolutely must take 64K page size into account, that
does not have to be reflected in the p_align value. If running on a 64K
kernel, the file will be loaded at a 64K page boundary by necessity. On
a 4K kernel, 64K alignment is not needed.
The glibc loader has been fixed to honor p_align:

fs/binfmt_elf: use PT_LOAD p_align values for suitable start address
This means that on 4K kernels, we will start to do extra work for 64K
p_align, but this pointless for pretty much all binaries (whose section
alignment rarely exceeds 16).
The minimum page size is used, instead of the maximum section alignment
due to this glibc bug:
https://sourceware.org/bugzilla/show_bug.cgi?id=28688
It has been fixed in glibc 2.35. But linker output must work on existing
glibc binaries.
1. Set p_align to the minimum page size while laying out segments aligning
to the maximum page size or section alignment. The run-time loader can
align segments to the minimum page size or above, depending on system page
size.
2. If -z max-page-size=NNN is used, p_align will be set to the maximum
page size or the largest section alignment.
3. If a section requires alignment higher than the minimum page size,
don't set p_align to the minimum page size.
4. If a section requires alignment higher than the maximum page size,
set p_align to the section alignment.
5. For objcopy, when the minimum page size != the maximum page size,
p_align may be set to the minimum page size while segments are aligned
to the maximum page size. In this case, the input p_align will be
ignored and the maximum page size will be used to align the ouput
segments.
6. Update linker to disallow the common page size > the maximum page size.
7. Update linker to avoid the common page size > the maximum page size.
8. Adjust pru_irq_map-1.d to expect p_align == sh_addralign:

FAIL: gdb.base/inferior-clone.exp: inferior 2: clone-inferior

Added inferior 2 on connection 1 (extended-remote localhost:2346)
(gdb) FAIL: gdb.base/inferior-clone.exp: inferior 2: clone-inferior
This fails because the testcase only expect the 'Added inferior 2' part

Fix by adjusting the testcase to a account for the possible trailing

gdb: fall back on sigpending + sigwait if sigtimedwait is not available
A call to sigwait was introduced that passes nullptr as the second
argument, this call is only reached if sigtimedwait is not supported.
The original patch was written for macOS, I assume on that target
passing nullptr as the second argument is fine.
On my GNU/Linux box, the man-page for sigwait doesn't mention that
nullptr is allowed for the second argument, so my assumption would be
that nullptr is not OK, and, if I change the '#ifdef
HAVE_SIGTIMEDWAIT' introduced by the above patch to '#if 0', and
rebuild on GNU/Linux, I see the same warning that I see on GNU/Hurd.
I propose that we stop passing nullptr as the second argument to
sigwait, and instead pass a valid int pointer. The value returned in
the int can then be used in an assert.
For testing, I (locally) made the change to the #ifdef I mentioned
above, compiled GDB, and ran the usual tests, this meant I was using
sigwait instead on sigtimedwait on GNU/Linux, I saw no regressions.

gas: rework handling of backslashes in quoted symbol names
Strange effects can result from the present handling, e.g.:
.if 1
"backslash\\":
.endif
yields first (correctly) "missing closing `"'" but then also "invalid
character '\' in mnemonic" and further "end of file inside conditional".
Symbols names ending in \ are in principle not expressable with that
scheme.
Instead of recording whether a backslash was seen, inspect the
subsequent character right away. Only accept \\ (meaning a single
backslash in the resulting symbol name) and \" (meaning an embedded
double quote in the resulting symbol name) for now, warning about any
other combination.
While perhaps not necessary immediately, also permit concatenated
strings to form a symbol name. This may become useful if going forward
we would want to support \<octal> or \x<hex> sequences, where closing
and re-opening quotes can be useful to delimit such sequences.
The ELF "Multibyte symbol names" test gets switched away from using
.set, as that would now also mean excluding nios2 and pru. By using
.equiv instead, even the existing #notarget can be dropped. (For h8300
the .section directive additionally needs attributes specified, to avoid
a target specific warning.)

Make the show logging messages more clear, while still keep the boolean
values explicit, such that we have:
...
$ ./gdb.sh -q -batch -ex "show logging"

ld: fix coff PE SEH
COFF_WITH_pex64 and COFF_WITH_peAArch64 can't be true at the same time.
That means that two conditionals that control the sorting of the .pdata section
became a falsum.
The testsuite doesn't catch this because the linker does the sorting and to link
you require library support from the unwinder so we can't test from binutils in
isolation.
