by QEMU, so allow the "etc/" namespace in this specific case.

On the host OS, various aspects of TLS operation are configurable.
In particular it is possible for the sysadmin to control the TLS
cipher/protocol algorithms that applications are permitted to use.
* Any given crypto library has a built-in default priority list
defined by the distro maintainer of the library package (or by
upstream).
* The "crypto-policies" RPM (or equivalent host OS package)
provides a config file such as "/etc/crypto-policies/config",
where the sysadmin can set a high level (library-independent)
policy.
The "update-crypto-policies --set" command (or equivalent) is
used to translate the global policy to individual library
representations, producing files such as
"/etc/crypto-policies/back-ends/*.config". The generated files,
if present, are loaded by the various crypto libraries to
override their own built-in defaults.
For example, the GNUTLS library may read
"/etc/crypto-policies/back-ends/gnutls.config".
* A management application (or the QEMU user) may overide the
system-wide crypto-policies config via their own config, if
they need to diverge from the former.
Thus the priority order is "QEMU user config" > "crypto-policies
system config" > "library built-in config".
Introduce the "tls-cipher-suites" object for exposing the ordered
list of permitted TLS cipher suites from the host side to the
guest firmware, via fw_cfg. The list is represented as an array
of bytes.
The priority at which the host-side policy is retrieved is given
by the "priority" property of the new object type. For example,
"priority=@SYSTEM" may be used to refer to
"/etc/crypto-policies/back-ends/gnutls.config" (given that QEMU
uses GNUTLS).
The firmware uses the IANA_TLS_CIPHER array for configuring
guest-side TLS, for example in UEFI HTTPS Boot.

seabios 1.14 release is planned for end of july,
early enough to make it into qemu 5.1-rc2 if
everything goes as planned.
Update seabios to a master snapshot now, so it'll get
test coverage during the freeze and the update to the
final version is much smaller (and should have bugfixes
only).

qemu_rdma_registration_stop() uses the ERROR() macro to create, report
to stderr, and store an Error object. The stored Error object is
never used, and its memory is leaked.
Even where ERROR() doesn't leak, it is ill-advised. The whole point
of passing an Error to the caller is letting the caller handle the
error. Error handling may report to stderr, to somewhere else, or not
at all. Also reporting in the callee mixes up concerns that should be
kept separate. Since I don't know what reporting to stderr is
supposed to accomplish, I'm not touching it.
Commit 2a1bc8bde7 "migration/rdma: rdma_accept_incoming_migration fix
error handling" plugged the same leak in
rdma_accept_incoming_migration().
Plug the memory leak the same way: keep the report part, delete the
store part.
The report part uses fprintf(). If it's truly an error, it should use
error_report() instead. But I don't know, so I leave it alone, just
like commit 2a1bc8bde7 did.

We don't emulate the memory controller but provide some default value
to prevent drivers getting unexpected 0.

Do not abort on unsupported value just print log and continue. While
display will likely be broken this prevents malicious guest to crash
QEMU causing denial of service.

This fixes horizontal mouse movement and pointer color with MacOS that
writes these registers with access size less than 4 so previously only
the last portion of access was effective overwriting previous partial
writes.

When doing reverse blit we need to check if source and dest overlap
but it is not trivial due to possible different base and pitch of
source and dest. Do rectangle overlap if base and pitch match,
otherwise just check if memory area containing the rects overlaps so
rects could possibly overlap.

Instead of open coding op with different sizes using a switch and type
casting it can be written more compactly using stn_he_p/ldn_he_p.

Some guests do 1x1 blits which is faster to do directly than calling a
function for it so avoid overhead in this case.

The bytes per pixel value can be calculated from format but it's used
freqently enough (and will be used more in subseqent patches) so store
it in a variable for better readabilty. Also drop some unneded 0x
prefix around where new variable is defined.
