Potentially tick-generating timer devices will gain a common property:
lock_tick_policy. It allows to encode 4 different ways how to deal with
tick events the guest did not process in time:
discard - ignore lost ticks (e.g. if the guest compensates for them
already)
delay - replay all lost ticks in a row once the guest accepts them
again
merge - if multiple ticks are lost, all of them are merged into one
which is replayed once the guest accepts it again
slew - lost ticks are gradually replayed at a higher frequency than
the original tick
Not all timer device will need to support all modes. However, all need
to accept the configuration via this common property.

Up to now, there was no special section for the different
host operating systems used with QEMU.
scripts/get_maintainer.pl did not show a maintainer for
OS specific files and patches.
Therefore I added three hosts systems:
* POSIX for the majority of host systems which are supported.
This includes BSD and Linux host systems.
* LINUX is a special case of POSIX needed for some Linux specific
files and directories.
* W32, W64 for a well known family of closed source operating systems.
I also added myself as a maintainer for W32, W64.

When 2c74c2cb4b added support for
the 'readonly' flag against 9p filesystems, it also made QEMU
add the O_NOATIME flag as a side-effect.
The O_NOATIME flag, however, may only be set by the file owner,
or a user with CAP_FOWNER capability. QEMU cannot assume that
this is the case for filesytems exported to QEMU.
eg, run QEMU as non-root, and attempt to pass the host OS
filesystem through to the guest OS with readonly enable.
The result is that the guest OS cannot open any files at
all.
If O_NOATIME is really required, it should be optionally
enabled via a separate QEMU command line flag.

In passthrough security model in local fs driver, after a file creation
chown and chmod are done to set the file credentials and mode as requested
by 9p client. But if there was a request to create a file with S_ISGID
bit, doing chown on that file resets the S_ISGID bit. So first call
chown and then invoking chmod with proper mode bit retains the S_ISGID
(if present/requested)
This resulted in LTP mknod02, mknod03, mknod05, open10 test case
failures. This patch fixes this issue.
man 2 chown
When the owner or group of an executable file are changed by an unprivileged
user the S_ISUID and S_ISGID mode bits are cleared. POSIX does not specify
whether this also should happen when root does the chown(); the Linux behavior
depends on the kernel version.

This is a very shallow integration. We register a TYPE_DEVICE but only use
QOM as basically a memory allocator. This will make all devices show up as
