  vcpu_dirty: share the same field in CPUState for all accelerators

This patch simply replaces the separate boolean field in CPUState that
kvm, hax (and upcoming hvf) have for keeping track of vcpu dirtiness
with a single shared field.

  qemu-doc: Add missing "@c man end" statements

Since commit 3f2ce724f1f1 ("Move the qemu-ga description into a
separate chapter"), the qemu.1 man page looks pretty much screwed
up, e.g. the title was "qemu-ga - QEMU Guest Agent" instead of
"qemu-doc - QEMU Emulator User Documentation". However, that movement
of the gemu-ga chapter is not the real problem, it just triggered
another bug in the qemu-doc.texi: There are some parts in the file
which introduce a "@c man begin OPTIONS" section, but never close
it again with "@c man end". After adding the proper end tags here,
the title of the man page is right again and the previously wrongly
tagged sections now also show up correctly in the man page, too.

  nbd: fix NBD over TLS

When attaching the NBD QIOChannel to an AioContext, the TLS channel should
be used, not the underlying socket channel.  This is because, trivially,
the TLS channel will be the one that we read/write to and thus the one
that will get the qio_channel_yield() call.

  target/i386: fix interrupt CPL error when using ist in x86-64

In do_interrupt64(), when interrupt stack table(ist) is enabled
and the the target code segment is conforming(e2 & DESC_C_MASK), the
old implementation always set new CPL to 0, and SS.RPL to 0.

This is incorrect for when CPL3 code access a CPL0 conforming code
segment, the CPL should remain unchanged. Otherwise higher privileged
code can be compromised.

The patch fix this for always set dpl = cpl when the target code segment
is conforming, and modify the last parameter `flags`, which contains
correct new CPL, in cpu_x86_load_seg_cache().

  target/i386: simplify handling of conforming code segments on interrupt

Move the handling of conforming code segments before the handling
of stack switch.

Because dpl == cpl after the new "if", it's now unnecessary to check
the C bit when testing dpl < cpl.  Furthermore, dpl > cpl is checked
slightly above the modified code, so the final "else" is unreachable
and we can remove it.

  Move CONFIG_KVM related definitions to kvm_i386.h

pc.h and sysemu/kvm.h are also included from common code (where
CONFIG_KVM is not available), so the #defines that depend on CONFIG_KVM
should not be declared here to avoid that anybody is using them in a
wrong way. Since we're also going to poison CONFIG_KVM for common code,
let's move them to kvm_i386.h instead. Most of the dummy definitions
from sysemu/kvm.h are also unused since the code that uses them is
only compiled for CONFIG_KVM (e.g. target/i386/kvm.c), so the unused
defines are also simply dropped here instead of being moved.

CONFIG_KVM is only defined for target-specific code, so nobody should
use it by accident in common code. To avoid such subtle bugs,
CONFIG_KVM is now marked as poisoned in common code. The header
include/sysemu/kvm.h is somewhat special since it is included
all over the place from common code, too, so we need some extra
logic via "#ifdef NEED_CPU_H" here to make sure that we can
compile all files without problems.

  cpu: Introduce a wrapper for tlb_flush() that can be used in common code

Commit 1f5c00cfdb8114c ("qom/cpu: move tlb_flush to cpu_common_reset")
moved the call to tlb_flush() from the target-specific reset handlers
into the common code qom/cpu.c file, and protected the call with
"#ifdef CONFIG_SOFTMMU" to avoid that it is called for linux-user
only targets. But since qom/cpu.c is common code, CONFIG_SOFTMMU is
*never* defined here, so the tlb_flush() was simply never executed
anymore. Fix it by introducing a wrapper for tlb_flush() in a file
that is re-compiled for each target, i.e. in translate-all.c.

  tests/test-char.c: Don't use main_loop_wait()'s return value

In QEMU's main_loop() we used to check whether we should do
a nonblocking call to main_loop(); this was deleted in commit e330c118f2a5,
because now that vCPUs always drop the I/O thread lock it is an unnecessary
optimization.

The loop in test-char.c copied the old QEMU main_loop() code, but
here the nonblocking check has never been necessary because this
standalone test case doesn't hold the I/O lock anyway. Remove it,
so we can drop the main_loop_wait() return value.

We avoid the awkwardness of ifdeffery to handle the 'ret'

of slirp_pollfds_poll() and slirp_pollfds_fill() already in

  checkpatch: should not use signal except for SIG_DFL or SIG_IGN

Using signal to establish a signal handler is not portable; on
SysV systems, the signal handler would be reset to SIG_DFL after
delivery, while BSD preserves the signal handler.  Daniel Berrange
reported that (to complicate matters further) the signal system call
has SysV behavior, but glibc signal() actually calls the sigaction
system call to provide BSD behavior.

However, using signal() to set a signal's disposition to SIG_DFL
or SIG_IGN is portable and is a relatively common occurrence in
QEMU source code, so allow that.

  cpu: move interrupt handling out of translate-common.c

translate-common.c will not be available anymore with --disable-tcg,
so we cannot leave cpu_interrupt_handler there.

Move the TCG-specific handler to accel/tcg/tcg-all.c, and adopt
KVM's handler as the default one, since it works just as well for
Xen and qtest.

Some of these functions are defined in ./accel/tcg/cputlb.c, which will

callers will also be compiled out for --disable-tcg.
