8b86d6d258 tcg: Hoist max_insns computation to tb_gen_code
In order to handle TB's that translate to too much code, we
need to place the control of the length of the translation
in the hands of the code gen master loop.

ede9a8a656 include: Move fprintf_function to disas/
The previous commits have eliminated fprintf_function outside
disassemblers, simplifying code and cleaning up the ugly type-punning
fprintf_function seems to attract.  Move fprintf_function to
include/disas/dis-asm.h to reduce the temptation to abuse it.

I considered renaming it to fprintf_ftype (reverting that part of
commit 6e2d864edf, v0.14.0) to get us closer to binutils, but I
figure the fork is too distant to make this worthwhile.

3979fca4b6 disas: Rename include/disas/bfd.h back to include/disas/dis-asm.h
Commit dc99065b5f (v0.1.0) added dis-asm.h from binutils.

Commit 43d4145a98 (v0.1.5) inlined bfd.h into dis-asm.h to remove the
dependency on binutils.

Commit 76cad71136 (v1.4.0) moved dis-asm.h to include/disas/bfd.h.
The new name is confusing when you try to match against (pre GPLv3+)
binutils.  Rename it back.  Keep it in the same directory, of course.

90c84c5600 qom/cpu: Simplify how CPUClass:cpu_dump_state() prints
CPUClass method dump_statistics() takes an fprintf()-like callback and

log_cpu_state() passes fprintf() and qemu_log_file.
hmp_info_registers() passes monitor_fprintf() and the current monitor

The callback gets passed around a lot, which is tiresome.  The
type-punning around monitor_fprintf() is ugly.

Drop the callback, and call qemu_fprintf() instead.  Also gets rid of
the type-punning, since qemu_fprintf() takes NULL instead of the
current monitor cast to FILE *.

19aaa4c3fd qemu-print: New qemu_fprintf(), qemu_vfprintf()
Code that doesn't want to know about current monitor vs. stdout
vs. stderr takes an fprintf_function callback and a FILE * argument to
pass to it.  Actual arguments are either fprintf() and stdout or
stderr, or monitor_fprintf() and the current monitor cast to FILE *.
monitor_fprintf() casts it right back, and is otherwise identical to
monitor_printf().  The type-punning is ugly.

New qemu_fprintf() and qemu_vprintf() address this need without type
punning: they are like fprintf() and vfprintf(), except they print to
the current monitor when passed a null FILE *.  The next commits will
put them to use.

fad866daa8 target: Clean up how the dump_mmu() print
The various dump_mmu() take an fprintf()-like callback and a FILE * to
pass to it, and so do their helper functions.  Passing around callback
and argument is rather tiresome.

Most dump_mmu() are called only by the target's hmp_info_tlb().  These
all pass monitor_printf() cast to fprintf_function and the current
monitor cast to FILE *.

SPARC's dump_mmu() gets also called from target/sparc/ldst_helper.c a
few times #ifdef DEBUG_MMU.  These calls pass fprintf() and stdout.

The type-punning is technically undefined behaviour, but works in
practice.  Clean up: drop the callback, and call qemu_printf()

8acb2a758b monitor: Simplify how -device/device_add print help
Commit a95db58f21 added monitor_vfprintf() as an error_printf()
generalized from stderr to arbitrary streams, then used it wrapped in
helper out_printf() to print -device/device_add help to stdout.  Use
qemu_printf() instead, and delete monitor_vfprintf() and out_printf().

6ade45f2ac char-pty: Print "char device redirected" message to stdout
char_pty_open() prints a "char device redirected to PTY_NAME (label
LABEL)" message to the current monitor or else to stderr.  This is not
an error, so it shouldn't go to stderr.  Print it to stdout instead.

Why is it even printed?  No other ChardevClass::open() prints anything
on success.  It's because you need to know PTY_NAME to actually use
this char device, e.g. like e.g. "socat STDIO,cfmakeraw FILE:PTY_NAME"
to use the monitor's readline interface.  You can get PTY_NAME with
"info chardev" (a.k.a. query-chardev for QMP), but only if you already
have a monitor.

637de4dba2 qemu-print: New qemu_printf(), qemu_vprintf() etc.
We commonly want to print to the current monitor if we have one, else
to stdout/stderr.  For stderr, have error_printf().  For stdout, all
we have is monitor_vfprintf(), which is rather unwieldy.  We often
print to stderr just because error_printf() is easier.

New qemu_printf() and qemu_vprintf() do exactly what's needed.  The
next commits will put them to use.

679cb8e1a1 monitor error: Make printf()-like functions return a value
printf() & friends return the number of characters written on success,
negative value on error.

monitor_printf(), monitor_vfprintf(), monitor_vprintf(),
error_printf(), error_printf_unless_qmp(), error_vprintf(), and
error_vprintf_unless_qmp() return void.  Some of them carry a TODO
comment asking for int instead.

Improve them to return int like printf() does.

This makes our use of monitor_printf() as fprintf_function slightly
less dirty: the function cast no longer adds a return value that isn't
there.  It still changes a parameter's pointer type.  That will be
addressed in a future commit.

monitor_vfprintf() always returns zero.  Improve it to return the
proper value.

5ab77f9aa3 s390x/kvm: Report warnings with warn_report(), not error_printf()
kvm_s390_mem_op() can fail in two ways: when !cap_mem_op, it returns
-ENOSYS, and when kvm_vcpu_ioctl() fails, it returns -errno set by
ioctl().  Its caller s390_cpu_virt_mem_rw() recovers from both
failures.

kvm_s390_mem_op() prints "KVM_S390_MEM_OP failed" with error_printf()
in the latter failure mode.  Since this is obviously a warning, use
warn_report().

Perhaps the reporting should be left to the caller.  It could warn on
failure other than -ENOSYS.

4c8b7c8b25 error: Fix error_report_err(), warn_report_err() hint printing
Before the from qerror_report() to error_setg(), hints looked like
this:

    qerror_report(QERR_MACRO, ... arguments ...);
    error_printf_unless_qmp(... hint ...);

error_printf_unless_qmp() made perfect sense: it printed exactly when
qerror_report() did.

After the conversion to error_setg():

    error_setg(errp, QERR_MACRO, ... arguments ...);
    error_printf_unless_qmp(... hint ...);

The "unless QMP part" still made some sense; in QMP context, the
caller generally uses the error as QMP response instead of printing
it.

However, everything else is wrong.  If the caller handles the error,
the hint gets printed anyway (unless QMP).  If the caller reports the
error, the hint gets printed *before* the report (unless QMP) or not
at all (if QMP).

Commit 50b7b000c9 fixed this by making hints a member of Error.  It
kept printing hints with error_printf_unless_qmp():

     void error_report_err(Error *err)
     {
	 error_report("%s", error_get_pretty(err));
    +    if (err->hint) {
    +        error_printf_unless_qmp("%s\n", err->hint->str);
    +    }
	 error_free(err);
     }

This is wrong.  We should (and now can) print the hint exactly when we
print the error.

The mistake has since been copied to warn_report_err() in commit
e43ead1d0b.

Fix both to use error_printf().

f5852efa29 log: Make glib logging go through QEMU
This commit adds a error_init() helper which calls
g_log_set_default_handler() so that glib logs (g_log, g_warning, ...)
are handled similarly to other QEMU logs. This means they will get a
timestamp if timestamps are enabled, and they will go through the
HMP monitor if one is configured.

This commit also adds a call to error_init() to the binaries
installed by QEMU. Since error_init() also calls error_set_progname(),
this means that *-linux-user, *-bsd-user and qemu-pr-helper messages
output with error_report, info_report, ... will slightly change: they
will be prefixed by the binary name.

glib debug messages are enabled through G_MESSAGES_DEBUG similarly to
the glib default log handler.

At the moment, this change will mostly impact SPICE logging if your
spice version is >= 0.14.1. With older spice versions, this is not going
to work as expected, but will not have any ill effect, so this call is
not conditional on the SPICE version.
