When we issue a cancel and clean up the RDMA channel
send a CONTROL_ERROR to get the destination to quit.
The rdma_cleanup code waits for the event to come back
from the rdma_disconnect; but that wont happen until the
destination quits and there's currently nothing to force
it.
Note this makes the case of a cancel work while the destination
is alive, and it already works if the destination is
truly dead. Note it doesn't fix the case where the destination
is hung (we get stuck waiting for the rdma_disconnect event).

control_desc[] is an array of strings that correspond to a
series of message types; they're used only for error messages, but if
the message type is seriously broken then we could go off the end of
the array.
Convert the array to a function control_desc() that bound checks.

When waiting for a WRID, if the other side dies we end up waiting
for ever with no way to cancel the migration.
Cure this by poll()ing the fd first with a timeout and checking

Fix a race where the destination might try and send the source a
WRID_READY before the source has done a post-recv for it.
rdma_post_recv has to happen after the qp exists, and we're
OK since we've already called qemu_rdma_source_init that calls
qemu_alloc_qp.
This corresponds to:
https://bugzilla.redhat.com/show_bug.cgi?id=1285044
The race can be triggered by adding a few ms wait before this
post_recv_control (which was originally due to me turning on loads of
debug).

This converts the RDMA code to provide a subclass of QIOChannel
that uses RDMA for the data transport.
This implementation of RDMA does not correctly handle non-blocking
mode. Reads might block if there was not already some pending data
and writes will block until all data is sent. This flawed behaviour
was already present in the existing impl, so appears to not be a
critical problem at this time. It should be on the list of things
to fix in the future though.
The RDMA code would be much better off it it could be split up in
a generic RDMA layer, a QIOChannel impl based on RMDA, and then
the RMDA migration glue. This is left as a future exercise for
the brave.

Currently if an application initiates an outgoing migration,
it may or may not, get an error reported back on failure. If
the error occurs synchronously to the 'migrate' command
execution, the client app will see the error message. This
is the case for DNS lookup failures. If the error occurs
asynchronously to the monitor command though, the error
will be thrown away and the client left guessing about
what went wrong. This is the case for failure to connect
to the TCP server (eg due to wrong port, or firewall
rules, or other similar errors).
In the future we'll be adding more scope for errors to
happen asynchronously with the TLS protocol handshake.
TLS errors are hard to diagnose even when they are well
reported, so discarding errors entirely will make it
impossible to debug TLS connection problems.
Management apps which do migration are already using
'query-migrate' / 'info migrate' to check up on progress
of background migration operations and to see their end
status. This is a fine place to also include the error
message when things go wrong.
This patch thus adds an 'error-desc' field to the
MigrationInfo struct, which will be populated when
the 'status' is set to 'failed':
(qemu) migrate -d tcp:localhost:9001
(qemu) info migrate
capabilities: xbzrle: off rdma-pin-all: off auto-converge: off zero-blocks: off compress: off events: off x-postcopy-ram: off
Migration status: failed (Error connecting to socket: Connection refused)
total time: 0 milliseconds
In the HMP, when doing non-detached migration, it is
also possible to display this error message directly
to the app.
(qemu) migrate tcp:localhost:9001
Error connecting to socket: Connection refused
Or with QMP
{
"execute": "query-migrate",
"arguments": {}
}
{
"return": {
"status": "failed",
"error-desc": "address resolution failed for myhost:9000: No address associated with hostname"
}
}

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

The coroutine files are currently referenced by the block-obj-y
variable. The coroutine functionality though is already used by
more than just the block code. eg migration code uses coroutine
yield. In the future the I/O channel code will also use the
coroutine yield functionality. Since the coroutine code is nicely
self-contained it can be easily built as part of the libqemuutil.a
library, making it widely available.
The headers are also moved into include/qemu, instead of the
include/block directory, since they are now part of the util
codebase, and the impl was never in the block/ directory
either.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

If the number of RAMBlocks was different on the source from the
destination, QEMU would hang waiting for a disconnect on the source
and wouldn't release from that hang until the destination was manually
killed.
Mark the stream as being in error, this causes the destination to die
and the source to carry on.

not managed to complete another migration after the 1st one, still

Use the order of incoming RAMBlocks from the source to record
an index number; that then allows us to sort the destination
local RAMBlock list to match the source.
Now that the RAMBlocks are known to be in the same order, this
simplifies the RDMA Registration step which previously tried to
match RAMBlocks based on offset (which isn't guaranteed to match).
Looking at the existing compress code, I think it was erroneously
relying on an assumption of matching ordering, which this fixes.

b) The hash gets recreated after deletion; fixed by making that
conditional on the hash being initialised.
While this function is currently only used during cleanup, Michael

The 'offset' field in RDMACompress and 'current_addr' field
in RDMARegister are commented as being offsets within a particular
RAMBlock, however they appear to actually be offsets within the
ram_addr_t space.
The code currently assumes that the offsets on the source/destination
match, this change removes the need for the assumption for these
structures by translating the addresses into the ram_addr_t space of
the destination host.
Note: An alternative would be to change the fields to actually
take the data they're commented for; this would potentially be
simpler but would break stream compatibility for those cases
that currently work.

The current code won't compile on 32 bit hosts because there are lots
of type casts between pointers and 64 bit integers.
Fix some of them.

Do not check for rdma->host being empty twice. This removes a large
"if" block, so code indentation is changed. While at it, remove an
ugly goto from the loop, replacing it with a cleaner if logic. And
finally, there's no need to initialize `ret' variable since is always
has a value.
