undoing the increments added in earlier commits. Revert this,

This problem affects s390x only if we are running without KVM.
Basically, S390CPU.irqstate is unused if we do not use KVM,
and thus no buffer is allocated.
This causes size=0, first_elem=NULL and n_elems=1 in
vmstate_load_state and vmstate_save_state. And the assert fails.
With this fix we can go back to the old behavior and support
VMS_VBUFFER with size 0 and nullptr.

The tls-creds parameter has a default value of NULL indicating
that TLS should not be used. Setting it to non-NULL enables
use of TLS. Once tls-creds are set to a non-NULL value via the
monitor, it isn't possible to set them back to NULL again, due
to current implementation limitations. The empty string is not
a valid QObject identifier, so this switches to use "" as the
default, indicating that TLS will not be used
The tls-hostname parameter has a default value of NULL indicating
the the hostname from the migrate connection URI should be used.
Again, once tls-hostname is set non-NULL, to override the default
hostname for x509 cert validation, it isn't possible to reset it
back to NULL via the monitor. The empty string is not a valid
hostname, so this switches to use "" as the default, indicating
that the migrate URI hostname should be used.
Using "" as the default for both, also means that the monitor
commands "info migrate_parameters" / "query-migrate-parameters"
will report existance of tls-creds/tls-parameters even when set
to their default values.

This also fixes the completely broken headings for flat and simple
unions in qemu-qmp-ref.7 and qemu-ga-ref.7, by sidestepping a bug in
texi2pod.pl. For instance, it mistranslates "@deftp {Simple Union}

PEP 8 advises:
In Python, single-quoted strings and double-quoted strings are the
same. This PEP does not make a recommendation for this. Pick a
rule and stick to it. When a string contains single or double
quote characters, however, use the other one to avoid backslashes
in the string. It improves readability.
The QAPI generators succeed at picking a rule, but fail at sticking to
it. Convert a bunch of double-quoted strings to single-quoted ones.

We traditionally mark optional members #optional in the doc comment.
Before commit 3313b61, this was entirely manual.
Commit 3313b61 added some automation because its qapi2texi.py relied
on #optional to determine whether a member is optional. This is no
longer the case since the previous commit: the only thing qapi2texi.py
still does with #optional is stripping it out. We still reject bogus
qapi-schema.json and six places for qga/qapi-schema.json.
Thus, you can't actually rely on #optional to see whether something is
optional. Yet we still make people add it manually. That's just
busy-work.
Drop the code to check, fix up and strip out #optional, along with all
instances of #optional. To keep it out, add code to reject it, to be
dropped again once the dust settles.

We silently fix missing #optional tags for QAPIDoc by appending a line
"#optional" to the section's .content. However, this interferes with
.__repr__ stripping trailing blank lines from .content.
Use new ArgSection instance variable .optional instead, and leave
.content alone.
To permit testing .optional in texi_body(), clean up texi_enum()'s
hack to add empty documentation for undocumented enum values: add an
ArgSection instead of ''.
