Add a new device, ivshmem-flat, which is similar to the ivshmem PCI but
does not require a PCI bus. It's meant to be used on machines like those
with Cortex-M MCUs, which usually lack a PCI/PCIe bus, e.g. lm3s6965evb
and mps2-an385.
The device currently only supports the sysbus bus.
The new
Since v1:
- Correct code style
- Correct trace event format strings
- Include minimum headers in ivshmem-flat.h
- Allow ivshmem_flat_recv_msg() take NULL
- Factored ivshmem_flat_connect_server() out
- Split sysbus-auto-wire controversial code in different patch
- Document QDev interface
Since v2:
Because now there is also an MMIO ivshmem device (ivshmem-flat.c), and
ivshmem.c is a PCI specific implementation, rename it to ivshmem-pci.c.

Add some handy string list functions for general use, and use them in
live migration functions. These will also be needed for cpr exec mode.
Changes in V5:
* renamed some variables and one function, replaced GStrv with char **
* aligned backslashes in QAPI_LIST_LENGTH
* restored cutils.h
Generalize hmp_split_at_comma() to take any delimiter string, rename
as str_split(), and move it to util/strList.c.
No functional change.

When guest page size > host page size, this test can fail
due to the SIGBUS protection hack. Avoid this by making

This option controls the host page size. From the mis-usage in
our own testsuite, this is easily confused with guest page size.
The only thing that occurs when changing the host page size is
that stuff breaks, because one cannot actually change the host
page size. Therefore reject all but the
Since alpha binaries are generally built for multiple
page sizes, it is trivial to allow the page size to vary.

AT_PAGESZ is supposed to advertise the guest page size.
The random adjustment made here using qemu_host_page_size
does not match anything else within linux-user.
The idea here is good, but should be done more systemically
via adjustment to TARGET_PAGE_SIZE.
