qemu: Set "qemu-event" thread identity
It may happen that qemuProcessStop() is called from "qemu-event"
thread. But this thread doesn't have any virIdentity set
(virIdentity being thread local) and therefore it may be unable
to open connection to secondary drivers. It is unable to do so
in split daemon scenario, because in there opening a connection
is coupled with copying current thread identity onto the
connection. Code-wise, virIdentityGetCurrent() returns NULL which
in turn makes virGetConnectGeneric() fail. This problem does not
occur in monolithic daemon scenario, because no identity copying
is done there.
Long story short, inability to open secondary driver connection
can lead to unwanted results. Therefore, do what
qemuProcessReconnectHelper() does - set the new thread identity
to be the one of the caller.

rpc: Temporarily stop accept()-ing new clients on EMFILE
This commit is related to 5de203f879 which I pushed a few days
ago. While that commit prioritized closing clients socket over
the rest of I/O process, this one goes one step further and
temporarily suspends processing new connection requests.
A brief recapitulation of the problem:
1) assume that libvirt is at the top of RLIMIT_NOFILE (that is no
new FDs can be opened).
2) we have a client trying to connect to a UNIX/TCP socket
Because of 2) our event loop sees POLLIN on the socket and thus
calls virNetServerServiceAccept(). But since no new FDs can be
opened (because of 1)) the request is not handled and we will get
the same event on next iteration. The poll() will exit
immediately because there is an event on the socket. Thus we end
up in an endless loop.
To break the loop and stop burning CPU cycles we can stop
listening for events on the socket and set up a timer tho enable
listening again after some time (I chose 5 seconds because of no
obvious reason).
There's another area where we play with temporarily suspending
accept() of new clients - when a client disconnects and we check
max_clients against number of current clients. Problem here is
that max_clients can be orders of magnitude larger than
RLIMIT_NOFILE but more importantly, what this code considers
client disconnect is not equal to closing client's FD.
A client disconnecting means that the corresponding client
structure is removed from the internal list of clients. Closing
of the client's FD is done from event loop - asynchronously.
To avoid this part stepping on the toes of my fix, let's make the
code NOP if socket timer (as described above) is active.

a VM with an attached TPM without having to run this program on the
command line before. This program needs to run once.
