migration: Cleanup incoming migration setup state change

Destination QEMU can setup incoming ports for two purposes: either a fresh
new incoming migration, in which QEMU will switch to SETUP for channel
establishment, or a paused postcopy migration, in which QEMU will stay in
POSTCOPY_PAUSED until kicking off the RECOVER phase.

Now the state machine worked on dest node for the latter, only because
migrate_set_state() implicitly will become a noop if the current state
check failed.  It wasn't clear at all.

Clean it up by providing a helper migration_incoming_state_setup() doing
proper checks over current status.  Postcopy-paused will be explicitly
checked now, and then we can bail out for unknown states.

migration: Rename thread debug names

The postcopy thread names on dest QEMU are slightly confusing, partly I'll
need to blame myself on 36f62f11e4 ("migration: Postcopy preemption
preparation on channel creation").  E.g., "fault-fast" reads like a fast
version of "fault-default", but it's actually the fast version of
"postcopy/listen".

Taking this chance, rename all the migration threads with proper rules.
Considering we only have 15 chars usable, prefix all threads with "mig/",
meanwhile identify src/dst threads properly this time.  So now most thread
names will look like "mig/DIR/xxx", where DIR will be "src"/"dst", except
the bg-snapshot thread which doesn't have a direction.

For multifd threads, making them "mig/{src|dst}/{send|recv}_%d".

We used to have "live_migration" thread for a very long time, now it's
called "mig/src/main".  We may hope to have "mig/dst/main" soon but not
yet.

tests/qtest/migration: Add a test for mapped-ram with passing of fds

Add a multifd test for mapped-ram with passing of fds into QEMU. This
is how libvirt will consume the feature.

There are a couple of details to the fdset mechanism:

- multifd needs two distinct file descriptors (not duplicated with
  dup()) so it can enable O_DIRECT only on the channels that do
  aligned IO. The dup() system call creates file descriptors that
  share status flags, of which O_DIRECT is one.

- the open() access mode flags used for the fds passed into QEMU need
  to match the flags QEMU uses to open the file. Currently O_WRONLY
  for src and O_RDONLY for dst.

Note that fdset code goes under _WIN32 because fd passing is not
supported on Windows.

migration: Add documentation for fdset with multifd + file

With the last few changes to the fdset infrastructure, we now allow
multifd to use an fdset when migrating to a file. This is useful for
the scenario where the management layer wants to have control over the
migration file.

By receiving the file descriptors directly, QEMU can delegate some
high level operating system operations to the management layer (such
as mandatory access control). The management layer might also want to
add its own headers before the migration stream.

Document the "file:/dev/fdset/#" syntax for the multifd migration with
mapped-ram. The requirements for the fdset mechanism are:

- the fdset must contain two fds that are not duplicates between
  themselves;

- if direct-io is to be used, exactly one of the fds must have the
  O_DIRECT flag set;

- the file must be opened with WRONLY on the migration source side;

- the file must be opened with RDONLY on the migration destination
  side.

monitor: fdset: Match against O_DIRECT

We're about to enable the use of O_DIRECT in the migration code and
due to the alignment restrictions imposed by filesystems we need to
make sure the flag is only used when doing aligned IO.

The migration will do parallel IO to different regions of a file, so
we need to use more than one file descriptor. Those cannot be obtained
by duplicating (dup()) since duplicated file descriptors share the
file status flags, including O_DIRECT. If one migration channel does
unaligned IO while another sets O_DIRECT to do aligned IO, the
filesystem would fail the unaligned operation.

The add-fd QMP command along with the fdset code are specifically
designed to allow the user to pass a set of file descriptors with
different access flags into QEMU to be later fetched by code that
needs to alternate between those flags when doing IO.

migration/multifd: Add direct-io support

When multifd is used along with mapped-ram, we can take benefit of a
filesystem that supports the O_DIRECT flag and perform direct I/O in
the multifd threads. This brings a significant performance improvement
because direct-io writes bypass the page cache which would otherwise
be thrashed by the multifd data which is unlikely to be needed again
in a short period of time.

To be able to use a multifd channel opened with O_DIRECT, we must
ensure that a certain aligment is used. Filesystems usually require a
block-size alignment for direct I/O. The way to achieve this is by
enabling the mapped-ram feature, which already aligns its I/O properly
(see MAPPED_RAM_FILE_OFFSET_ALIGNMENT at ram.c).

By setting O_DIRECT on the multifd channels, all writes to the same
file descriptor need to be aligned as well, even the ones that come
from outside multifd, such as the QEMUFile I/O from the main migration
code. This makes it impossible to use the same file descriptor for the
QEMUFile and for the multifd channels. The various flags and metadata
written by the main migration code will always be unaligned by virtue
of their small size. To workaround this issue, we'll require a second
file descriptor to be used exclusively for direct I/O.

The second file descriptor can be obtained by QEMU by re-opening the
migration file (already possible), or by being provided by the user or
management application (support to be added in future patches).

monitor: Stop removing non-duplicated fds

monitor_fdsets_cleanup() currently has three responsibilities:

1- Remove the fds that have been marked for removal(->removed=true) by
   qmp_remove_fd(). This is overly complicated, but ok.

2- Remove any file descriptors that have been passed into QEMU and
   never duplicated[1,2]. A file descriptor without duplicates
   indicates that no part of QEMU has made use of it. This is
   problematic because the current implementation does it only if the
   guest is not running and the monitor is closed.

3- Remove/free fdsets that have become empty due to the above
   removals. This is ok.

The scenario described in (2) is starting to show some cracks now that
we're trying to consume fds from the migration code:

- Doing cleanup every time the last monitor connection closes works to
  reap unused fds, but also has the side effect of forcing the
  management layer to pass the file descriptors again in case of a
  disconnect/re-connect, if that happened to be the only monitor
  connection.

  Another side effect is that removing an fd with qmp_remove_fd() is
  effectively delayed until the last monitor connection closes.

  The usage of mon_refcount is also problematic because it's racy.

- Checking runstate_is_running() skips the cleanup unless the VM is
  running and avoids premature cleanup of the fds, but also has the
  side effect of blocking the legitimate removal of an fd via
  qmp_remove_fd() if the VM happens to be in another state.

  This affects qmp_remove_fd() and qmp_query_fdsets() in particular
  because requesting a removal at a bad time (guest stopped) might
  cause an fd to never be removed, or to be removed at a much later
  point in time, causing the query command to continue showing the
  supposedly removed fd/fdset.

Note that file descriptors that *have* been duplicated are owned by
the code that uses them and will be removed after qemu_close() is
called. Therefore we've decided that the best course of action to
avoid the undesired side-effects is to stop managing non-duplicated
file descriptors.

linux-user: Make TARGET_NR_setgroups affect only the current thread

Like TARGET_NR_setuid, TARGET_NR_setgroups should affect only the
calling thread, and not the entire process. Therefore, implement it
using a syscall, and not a libc call.

hw/intc: Introduce x-query-interrupt-controllers QMP command

This is a counterpart to the HMP "info pic" command. It is being
added with an "x-" prefix because this QMP command is intended as an
adhoc debugging tool and will thus not be modelled in QAPI as fully
structured data, nor will it have long term guaranteed stability.
The existing HMP command is rewritten to call the QMP command.
