This reverts commit 8d5a24c83d.
Compiling all virtio-gpu objects into a single module isn't a good plan
because the individual objects have different CONFIG_* dependencies.
Leads to module load failures on s390x due to vga support being
disabled, which in turn breaks '-device virtio-gpu-device' (flagged by
travis ci).
So back to the drawing board for modular virtio-gpu ...

This is a cleanup patch to follow-up the patch which introduced TSAN.
This patch makes separate start_switch_fiber_ functions for TSAN and ASAN.
This does two things:
1. Unrelated ASAN and TSAN code is separate and each function only
has arguments that are actually needed.
2. The co->tsan_caller_fiber and co->tsan_co_fiber fields are only
access from within #ifdef CONFIG_TSAN.

https://lists.gnu.org/archive/html/qemu-devel/2019-10/msg02102.html
My mistake here, I took my eyes of the mailing list after I got the
initial thumbs up. This patch follows up on Markus comments in the
above link.
Purpose of this patch:
We want to print guest name for errors, warnings and info messages. This
was the first of two patches the second being MCE errors targeting a VM
with guest name prepended. But in a large fleet we see many other
errors that disable a VM or crash it. In a large fleet and centralized
logging having the guest name enables identify of owner and customer.

When all we do with an Error we receive into a local variable is

right away. Convert

Not exactly elegant, I'm afraid.
The "when != lbl:" is necessary to avoid transforming
if (fun(args, &err)) {
goto out
}
...
out:
error_propagate(errp, err);
even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().
Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly. I don't know what exactly "when strict" does, only that
it helps here.
The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err". For
an example where it's too narrow, see vfio_intx_enable().
Silently fails to convert hw/arm/armsse.c, because Coccinelle gets
confused by ARMSSE being used both as typedef and function-like macro
there. Converted manually.
Line breaks tidied up manually. One nested declaration of @local_err
deleted manually. Preexisting unwanted blank line dropped in
hw/riscv/sifive_e.c.

opt_set() frees its argument @value on failure. Slightly unclean;
functions ideally do nothing on failure.
To tidy this up, move opt_create() from opt_set() into its callers,
along with the cleanup. Rename opt_set() to opt_validate(), noting
its similarity to qemu_opts_validate(). Drop redundant parameter
@opts; use opt->opts instead.

Note that we can't drop parallels_open()'s error_propagate() here. We
continue to execute it even in the converted case. It's a no-op then:

Recent versions of Solaris (v11.4) now feature an openpty() function,
too, causing a build failure since we ship our own implementation of
openpty() for Solaris in util/qemu-openpty.c so far. Since there are
now both variants available in the wild, with and without this function
(and illumos is said to not have this function yet), let's introduce a
proper HAVE_OPENPTY define for this to fix the build failure.

Current implementation of LLVM's SafeStack is not compatible with
code that uses an alternate stack created with sigaltstack().
Since coroutine-sigaltstack relies on sigaltstack(), it is not
compatible with SafeStack. The resulting binary is incorrect, with
different coroutines sharing the same unsafe stack and producing
undefined behavior at runtime.
In the future LLVM may provide a SafeStack implementation compatible with
sigaltstack(). In the meantime, if SafeStack is desired, the coroutine
implementation from coroutine-ucontext should be used.
As a safety check, add a control in coroutine-sigaltstack to throw a
preprocessor #error if SafeStack is enabled and we are trying to
use coroutine-sigaltstack to implement coroutines.

LLVM's SafeStack instrumentation does not yet support programs that make
use of the APIs in ucontext.h
With the current implementation of coroutine-ucontext, the resulting
binary is incorrect, with different coroutines sharing the same unsafe
stack and producing undefined behavior at runtime.
This fix allocates an additional unsafe stack area for each coroutine,
and sets the new unsafe stack pointer before calling swapcontext() in
qemu_coroutine_new.
This is the only place where the pointer needs to be manually updated,
since sigsetjmp/siglongjmp are already instrumented by LLVM to properly
support SafeStack.
The additional stack is then freed in qemu_coroutine_delete.

The glib event loop does not call fdmon_io_uring_wait() so fd handlers
waiting to be submitted build up in the list. There is no benefit is
using io_uring when the glib GSource is being used, so disable it
instead of implementing a more complex fix.
This fixes a memory leak where AioHandlers would build up and increasing
amounts of CPU time were spent iterating them in aio_pending(). The
symptom is that guests become slow when QEMU is built with io_uring
support.

The io_uring file descriptor monitoring implementation has an internal
list of fd handlers that are pending submission to io_uring.
fdmon_io_uring_destroy() deletes all fd handlers on the list.
Don't delete fd handlers directly in fdmon_io_uring_destroy() for two
reasons:
1. This duplicates the aio-posix.c AioHandler deletion code and could
become outdated if the struct changes.
2. Only handlers with the FDMON_IO_URING_REMOVE flag set are safe to
remove. If the flag is not set then something still has a pointer to
the fd handler. Let aio-posix.c and its user worry about that. In
practice this isn't an issue because fdmon_io_uring_destroy() is only
called when shutting down so all users have removed their fd
handlers, but the next patch will need this!

Blindly setting FD_CLOEXEC without a read-modify-write will
inadvertently clear any other intentionally-set bits, such as a
proposed new bit for designating a fd that must behave in 32-bit mode.
However, we cannot use our wrapper qemu_set_cloexec(), because that
wrapper intentionally abort()s on failure, whereas the probe here
intentionally tolerates failure to deal with incorrect socket
activation gracefully. Instead, fix the code to do the proper
read-modify-write.

Compress two lines into a single line if immediate return statement is found.
It also remove variables progress, val, data, ret and sock
as they are no longer needed.
Remove space between function "mixer_load" and '(' to fix the
checkpatch.pl error:-
ERROR: space prohibited between function name and open parenthesis '('

qdict_iter() has just three uses and no test coverage. Replace by
qdict_first(), qdict_next() for more concise code and less type
punning.

is_valid_option_list()'s purpose is ensuring qemu-img.c's can safely
join multiple parameter strings separated by ',' like this:
g_strdup_printf("%s,%s", params1, params2);
How it does that is anything but obvious. A close reading of the code
reveals that it fails exactly when its argument starts with ',' or
ends with an odd number of ','. Makes sense, actually, because when
the argument starts with ',', a separating ',' preceding it would get
escaped, and when it ends with an odd number of ',', a separating ','
following it would get escaped.
Move it to qemu-img.c and rewrite it the obvious way.

When opts_parse() sets @invalidp to true, qemu_opts_parse_noisily()
uses has_help_option() to decide whether to print help. This parses
the input string a second time.
Easy to avoid: replace @invalidp by @help_wanted.

has_help_option() uses its own parser. It's inconsistent with
qemu_opts_parse(), as demonstrated by test-qemu-opts case
/qemu-opts/has_help_option. Fix by reusing the common parser.
