Remove the slirp submodule (i.e. compile only with an external libslirp)

Since QEMU 7.1 we don't support Ubuntu 18.04 anymore, so the last big
important Linux distro that did not have a pre-packaged libslirp has
been dismissed. All other major distros seem to have a libslirp package
in their distribution already - according to repology.org:

Fedora 35: 4.6.1
CentOS 8 (RHEL-8): 4.4.0
Debian 11: 4.4.0
OpenSUSE Leap 15.3: 4.3.1
Ubuntu LTS 20.04: 4.1.0
FreeBSD Ports: 4.7.0
NetBSD pkgsrc: 4.7.0
Homebrew: 4.7.0
MSYS2 mingw: 4.7.0

The only one that was still missing a libslirp package is OpenBSD - but
the next version (OpenBSD 7.2 which will be shipped in October) is going
to include a libslirp package. Since QEMU 7.2 will be published after
OpenBSD 7.2, we should be fine there, too.

So there is no real urgent need for keeping the slirp submodule in
the QEMU tree anymore. Thus let's drop the slirp submodule now and
rely on the libslirp packages from the distributions instead.

configure: Add -Wno-gnu-variable-sized-type-not-at-end

A Linux headers update to v6.0-rc switches some definitions from GNU
'zero-length-array' extension to the C-standard-defined flexible array
member. e.g.

struct kvm_msrs {
__u32 nmsrs; /* number of msrs in entries */
__u32 pad;

- struct kvm_msr_entry entries[0];
+ struct kvm_msr_entry entries[];
};

Those (unlike the GNU zero-length-array) have some extra restrictions like
'this must be put at the end of a struct', which clang build would complain
about. e.g. the current code

struct {
struct kvm_msrs info;
struct kvm_msr_entry entries[1];
} msr_data = { }

generates the warning like:

target/i386/kvm/kvm.c:2868:25: error: field 'info' with variable sized
type 'struct kvm_msrs' not at the end of a struct or class is a GNU
extension [-Werror,-Wgnu-variable-sized-type-not-at-end]
struct kvm_msrs info;
^
In fact, the variable length 'entries[]' field in 'info' is zero-sized in
GNU defined semantics, which can give predictable offset for 'entries[1]'
in local msr_data. The local defined struct is just there to force a stack
allocation large enough for 1 kvm_msr_entry, a clever trick but requires to
turn off this clang warning.

configure: Avoid use of 'local' as it is non-POSIX

We use the non-POSIX 'local' keyword in just two places in configure;
rewrite to avoid it.

In do_compiler(), just drop the 'local' keyword. The variable
'compiler' is only used elsewhere in the do_compiler_werror()
function, which already uses the variable as a normal non-local one.

In probe_target_compiler(), $try and $t are both local; make them
normal variables and use a more obviously distinct variable name
for $t.

This commit adds quotes in some places which:

It doesn't attempt fix all of the places shellcheck finds errors,
or even all the ones which are easy to fix. It's just a random
sampling which is hopefully easy to review and which cuts
down the size of the problem for next time somebody wants to
try to look at shellcheck errors.

Therefore, do not clear them prior to returning from probe_target_compiler.

configure: Drop dead code attempting to use -msmall-data on alpha hosts

In commit 823eb013452e93d we moved the setting of ARCH from configure
to meson.build, but we accidentally left behind one attempt to use
$ARCH in configure, which was trying to add -msmall-data to the
compiler flags on Alpha hosts. Since ARCH is now never set, the test
always fails and we never add the flag.

There isn't actually any need to use this compiler flag on Alpha:
the original intent was that it would allow us to simplify our TCG
codegen on that platform, but we never actually made the TCG changes
that would rely on -msmall-data.

Drop the effectively-dead code from configure, as we don't need it.

This was spotted by shellcheck:

In ./configure line 2254:
case "$ARCH" in
^---^ SC2153: Possible misspelling: ARCH may not be assigned, but arch is.

configure: Don't use bash-specific string-replacement syntax

The variable string-replacement syntax ${var/old/new} is a bashism
(though it is also supported by some other shells), and for instance
does not work with the NetBSD /bin/sh, which complains:
../src/configure: 687: Syntax error: Bad substitution

Replace it with a more portable sed-based approach, similar to
what we already do in quote_sh().

Note that shellcheck also diagnoses this:

In ./configure line 687:
e=${e/'\'/'\\'}
^-----------^ SC2039: In POSIX sh, string replacement is undefined.
^-- SC1003: Want to escape a single quote? echo 'This is how it'\''s done'.

configure: Add braces to clarify intent of $emu[[:space:]]

In shell script syntax, $var[something] is not special for variable
expansion: $var is expanded. However, as it can look as if it were
intended to be an array element access (the correct syntax for which
is ${var[something]}), shellcheck recommends using explicit braces
around ${var} to clarify the intended expansion.

This fixes the warning:

In ./configure line 2346:
