Enable NVG and NVC VST tables for index compression which indicates the number

XIVE offers a 'cache watch facility', which allows software to read/update

When doing file migration, QEMU accepts an offset that should be
skipped when writing the migration stream to the file. The purpose of
the offset is to allow the management layer to put its own metadata at
the start of the file.
We have tests for this in migration-test, but only testing that the

The tests are only allowed to run in systems that know about the
O_DIRECT flag and in filesystems which support it.
Note: this also brings back migrate_set_parameter_bool() which went
away when we removed the compression tests. I copied it verbatim.

When the "file:" migration support was added we missed the special
case in the qemu_open_old implementation that allows for a particular
file name format to be used to refer to a set of file descriptors that
have been previously provided to QEMU via the add-fd QMP command.
When using this fdset

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
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

We forgot to drop the reference to the QIOChannel in the error path of

Hi,
Not many changes since v2:
- new patch 1: drop IOC reference on offset check failure
- dropped 2 patches adding direct-io to the single threaded
migration. We have agreed to use multifd with 1 channel for that
use-case.

Those functions are not needed, one remove function should already
work. Clean it up.
Here the code doesn't really care about whether we need to keep that dupfd
around if close() failed: when that happens something got very wrong,
keeping the dup_fd around the fdsets may not
Introduce new functions to remove and free no longer used fds and
fdsets.
We need those to decouple the remove/free routines from
monitor_fdset_cleanup() which will go away in the next patches.
The new functions:
- monitor_fdset_free/_if_empty() will be used when a monitor
connection closes

Darwin uses a subtly different version of the setrlimit() syscall as

Destination QEMU can setup incoming ports for two purposes: either a fresh

Most of them are not needed, we can stick with one ifdef inside
postcopy_recover_fail() so as to cover the scm right tricks only.
The tests won't run on windows anyway due to has_uffd always false.
