dump_init() first computes the size of the dump, taking the filter
area into account, and fails if its zero. It then looks for memory in
the filter area, and fails if there is none.
This is redundant: if the size of the dump is zero, there is no
memory, and vice versa. Delete this check.

Zero @length is rejected with "Invalid parameter 'length'". Improve
to "parameter 'length' expects a non-zero length".
qemu_open_old() is a wrapper around qemu_open_internal() that throws
away error information. Switch to the wrapper that doesn't:
qemu_create(). Example improvement:
(qemu) dump-guest-memory /dev/fdset/x 0 1
Error: Could not open '/dev/fdset/x': Invalid argument
becomes
Error: Could not parse fdset /dev/fdset/x
@protocol values not starting with "fd:" or "file:" are rejected with
"Invalid parameter 'protocol'". Improve to "parameter 'protocol' must
start with 'file:' or 'fd:'".
While there, make the conditional checking @protocol a little more
obvious.

A few QMP command can work with named file descriptors.
The only way to create a named file descriptor used to be QMP command
getfd, which only works on POSIX hosts. Thus, named file descriptors
were actually usable only there.
They became usable on Windows hosts when we added QMP command
get-win32-socket (commit 4cda177c601 "qmp: add 'get-win32-socket'").
Except in dump-guest-memory, because qmp_dump_guest_memory() compiles
its named file descriptor code only #if !defined(WIN32).
Compile it unconditionally, like we do for the other commands
supporting them.

The QMP dump API represents the dump format as an enumeration. Add three
new enumerators, one for each supported kdump compression, each named
"kdump-raw-*".
For the HMP command line, rather than adding a new flag corresponding to
each format, it seems more human-friendly to add a single flag "-R" to
switch the kdump formats to "raw" mode. The choice of "-R" also
correlates nicely to the "makedumpfile -R" option, which would serve to
reassemble a flattened vmcore.

The flattened format (currently output by QEMU) is used by makedumpfile
only when it is outputting a vmcore to a file which is not seekable. The
flattened format functions essentially as a set of instructions of the
form "seek to the given offset, then write the given bytes out".
The flattened format can be reconstructed using makedumpfile -R, or
makedumpfile-R.pl, but it is a slow process because it requires copying
the entire vmcore. The flattened format can also be directly read by
crash, but still, it requires a lengthy reassembly phase.
To sum up, the flattened format is not an ideal one: it should only be
used on files which are actually not seekable. This is the exact
strategy which makedumpfile uses, as seen in the implementation of
"write_buffer()" in makedumpfile [1]. However, QEMU has always used the
flattened format. For compatibility it is best not to change the default
output format without warning. So, add a flag to DumpState which changes
the output to use the normal (i.e. raw) format. This flag will be added
to the QMP and HMP commands in the next change.

In a two-stage translation, the result of the BTI guarded bit should
be the guarded bit from the first stage of translation, as there is
no BTI guard information in stage two. Our code tried to do this,
but got it wrong, because we currently have two fields where the GP
bit information might live (ARMCacheAttrs::guarded and
CPUTLBEntryFull::extra::arm::guarded), and we were storing the GP bit
in the latter during the stage 1 walk but trying to copy the former
in combine_cacheattrs().
Remove the duplicated storage, and always use the field in
CPUTLBEntryFull; correctly propagate the stage 1 value to the output
in get_phys_addr_twostage().
Note for stable backports: in v8.0 and earlier the field is named
result->f.guarded, not result->f.extra.arm.guarded.

Most of the registers used by the FEAT_MOPS instructions cannot use
31 as a register field value; this is CONSTRAINED UNPREDICTABLE to
NOP or UNDEF (we UNDEF). However, it is permitted for the "source
value" register for the memset insns SET* to be 31, which (as usual
for most data-processing insns) means it should be the zero register
XZR. We forgot to handle this case, with the effect that trying to
set memory to zero with a "SET* Xd, Xn, XZR" sets the memory to
the value that happens to be in the low byte of SP.
Handle XZR when getting the SET* data value from the register file.

The AArch64 ELF hwcap2 field is 64 bits, but our get_elf_hwcap2()
works with uint32_t, so it accidentally fails to report any hwcaps
over bit 31. Use uint64_t here.
The Arm hwcap2 is only 32 bits (because the ELF format makes these
fields be the size of "long" in the ABI), but since it shares the
prototype declaration for get_elf_hwcap2() it is easier to also
expand it to 64 bits.
The only hwcap fields we implement already that are affected by this
are the HBC and MOPS ones, neither of which were implemented in a
previous release, so this doesn't need backporting to older stable
branches.

Now that we have converted to qdev, we can use the newer
qemu_input_handler_register() API rather than the legacy
qemu_add_kbd_event_handler().
Since we only have one user, take the opportunity to convert
from scancodes to QCodes, rather than using
qemu_input_key_value_to_scancode() (which adds an 0xe0
prefix and encodes up/down indication in the scancode,
which our old handler function then had to reverse). That
lets us drop the old state field which was tracking whether
we were halfway through a two-byte scancode.

RDMA based transport backend for 'migrate'/'migrate-incoming' QAPIs
accept new wire protocol of MigrateAddress struct.
It is achived by parsing 'uri' string and storing migration parameters
required for RDMA connection into well defined InetSocketAddress struct.

This patch parses 'migrate' and 'migrate-incoming' QAPI's 'uri'
string containing migration connection related information
and stores them inside well defined 'MigrateAddress' struct.
Fabiano fixed for "file" transport.

This patch introduces well defined MigrateAddress struct
and its related child objects.
The existing argument of 'migrate' and 'migrate-incoming' QAPI
- 'uri' is of type string. The current implementation follows
double encoding scheme for fetching migration parameters like
'uri' and this is not an ideal design.
Motive for intoducing struct level design is to prevent double
encoding of QAPI arguments, as Qemu should be able to directly
use the QAPI arguments without any level of encoding.
Note: this commit only adds the type, and actual uses comes
in later commits.
Fabiano fixed for "file" transport.

Now we have a Error** passed into the return path thread stack, which is
even clearer than an int retval. Change ram_dirty_bitmap_reload() and the
callers to use a bool instead to replace errnos.
