input: Document why x-input-send-event is still experimental
qapi: Document introspection stability considerations
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

The x-input-send-event command was introduced in 2.2 with mention
that it is experimental, but now that several releases have elapsed
without any changes, it would be nice to document why that was done
and should still remain experimental in 2.5.
Meanwhile, our documentation states that we prefer 'lower-case',
rather than 'CamelCase', for qapi enum values. The InputButton and
InputAxis enums violate this convention. However, because they are
currently used primarily for generating code that is used internally;
and their only exposure through QMP is via the experimental
'x-input-send-event' command, we are free to change their spelling.
Of course, it would be nicer to delay such a change until the same
time we promote the command to non-experimental. Adding
documentation will help us remember to do that rename.
We have plans to tighten the qapi generator to flag instances of
inconsistent use of naming conventions; if that lands first, it
will just need to whitelist these exceptions until the time we
settle on the final interface.
Fix a typo in the docs for InputAxis while at it.

We are not ready (and might never be ready) to declare
introspection stable between releases. Clients written to
control multiple versions of qemu, and desiring to know
whether a particular member is supported for a given
command, must be prepared to locate that member in spite
of qapi changes that may affect the member's location or
type within the overall object, even though such changes
did not break QMP wire back-compatibility.

First of all, RESET_OWNER message is sent incorrectly, as it's sent
before GET_VRING_BASE. And the reset message would let the later call
get nothing correct.
And, sending SET_VRING_ENABLE at stop, which has already been done,
makes more sense than RESET_OWNER.

Drop the libseccomp required version back to 2.1.0, restoring the ability
to build w/ --enable-seccomp on Ubuntu 14.04.
Commit 4cc47f8b3cc4f32586ba2f7fce1dc267da774a69 tightened the dependency
on libseccomp from version 2.1.0 to 2.1.1. This broke building on Ubuntu
14.04, the current Ubuntu LTS release. The commit message didn't mention
any specific functional need for 2.1.1, just that it was the most recent
stable version at the time. I reviewed the changes between 2.1.0 and 2.1.1,
but it looks like that update just contained minor fixes and cleanups - no
obvious (to me) new interfaces or critical bug fixes.

This is a revert of ae6e8ef11e6cb, but with a bit of refactoring,
and also specifically adding arm/aarch64, rather than all
architectures. Currently, libseccomp code appears to also support
mips, ppc, and s390. We could therefore allow qemu to enable
seccomp for those platforms as well, with additional configure
patches, given they're tested and proven to work.

Peter reported a lock error on MacOS after my a82d593b
patch.
migrate_get_current does one-time initialisation of
a bunch of variables.
migrate_init does reinitialisation even on a 2nd
migrate after a cancel.
The problem here was that I'd initialised the mutex
in migrate_get_current, and the memset in migrate_init
corrupted it.
Remove the memset and replace it by explicit initialisation
of fields that need initialising; this also turns out to be simpler
than the old code that had to preserve some fields.
