Fixes test regression introduced in commit 8e2e4780.

* daemon/libvirtd.c (daemonConfigLoad): Add argument.
(main): Update caller.

It is common for the $HOME/.libvirt/libvirtd.conf file to not
exist. Treat this situation as non-fatal since we can carry
on with our default settings just fine.

* daemon/libvirtd.c: Treat ENOENT as non-fatal when loading
  config

The dispatch for the CLOSE RPC call was invoking the method
virNetServerClientClose(). This caused the client connection
to be immediately terminated. This meant the reply to the
final RPC message was never sent. Prior to the RPC rewrite
we merely flagged the connection for closing, and actually
closed it when the next RPC call dispatch had completed.

* daemon/remote.c: Flag connection for a delayed close
* daemon/stream.c: Update to use new API for closing
  failed connection
* src/rpc/virnetserverclient.c, src/rpc/virnetserverclient.h:
  Add support for a delayed connection close. Rename the
  virNetServerClientMarkClose method to virNetServerClientImmediateClose
  to clarify its semantics

If a client disconnects while it has a stream active, there is
a race condition which could see libvirtd crash. This is because
the client struct may be freed before the last stream event has
triggered. This is trivially solved by holding an extra reference
on the client for the stream callbak

* daemon/stream.c: Acquire reference on client when adding the
  stream callback

This patch adds #if HAVE_SASL where needed in libvirtd.h

Detected by Coverity; only strikes on OOM so not serious.

* daemon/libvirtd.c (daemonPidFilePath): Plug leak.

* daemon/libvirtd.c, daemon/remote.c: Add #if HAVE_SASL and
  suitable function stubs to allow build without SASL

If a message packet for a invalid stream is received it is just
free'd. This is not good because it doesn't let the client RPC
request counter decrement. If a stream is shutdown with pending
packets the message also isn't released properly because of an
incorrect header type

* daemon/stream.c: Fix message header type
* src/rpc/virnetserverprogram.c: Send dummy reply instead of
  free'ing ignored stream message

The stream code was reusing a stream message object before
it was removed from the linked list of filtered messages.
This caused any later queued messages to be completely lost.

* daemon/stream.c: Delay reuse of stream message until
  after it is removed from the queue

The virNetServerClient object had a hardcoded limit of 10 requests
per client. Extend constructor to allow it to be passed in as a
configurable variable. Wire this up to the 'max_client_requests'
config parameter in libvirtd

* daemon/libvirtd.c: Pass max_client_requests into services
* src/rpc/virnetserverservice.c, src/rpc/virnetserverservice.h: Pass
  nrequests_client_max to clients
* src/rpc/virnetserverclient.c, src/rpc/virnetserverclient.h: Allow
  configurable request limit

Version 1.3 of <sys/sdt.h> uses this macro

  #define STAP_CAST(t) (size_t)t

that breaks like this if t is a function

  remote.c:1775: error: cast from function call of type 'const char *'
  to non-matching type 'long unsigned int' [-Wbad-function-cast]

For that to work it should probably look like this

  #define STAP_CAST(t) ((size_t)(t))

In systemtap 1.4 this was completely rewritten.

Anyway, before commit df0b57a9 t was always a variable, but now
also a function is used here, namely virNetSASLSessionGetIdentity.

Use an intermediate variable to avoid this problem.

libvirtd now uses the generic RPC code for MDNS, so its
custom mdns APIs are no longer required

* daemon/mdns.c, daemon/mdns.h: Removed obsolete files

This guts the libvirtd daemon, removing all its networking and
RPC handling code. Instead it calls out to the new virServerPtr
APIs for all its RPC & networking work

As a fallout all libvirtd daemon error reporting now takes place
via the normal internal error reporting APIs. There is no need
to call separate error reporting APIs in RPC code, nor should
code use VIR_WARN/VIR_ERROR for reporting fatal problems anymore.

* daemon/qemu_dispatch_*.h, daemon/remote_dispatch_*.h: Remove
  old generated dispatcher code
* daemon/qemu_dispatch.h, daemon/remote_dispatch.h: New dispatch
  code
* daemon/dispatch.c, daemon/dispatch.h: Remove obsoleted code
* daemon/remote.c, daemon/remote.h: Rewrite for new dispatch
  APIs
* daemon/libvirtd.c, daemon/libvirtd.h: Remove all networking
  code
* daemon/stream.c, daemon/stream.h: Update for new APIs
* daemon/Makefile.am: Link to libvirt-net-rpc-server.la

We already have a public virDomainPinVcpu, which implies that
Pin and Vcpu are treated as separate words.  Unreleased commit
e261987c introduced virDomainGetVcpupinInfo as the first public
API that used Vcpupin, although we had prior internal uses of
that spelling.  For consistency, change the spelling to be two
words everywhere, regardless of whether pin comes first or last.

Integer overflow and remote code are never a nice mix.

* src/remote/remote_driver.c (remoteDomainGetVcpus): Avoid overflow
on sending rpc.
* daemon/remote.c (remoteDispatchDomainGetVcpus): Avoid overflow on
receiving rpc.

Since we virEventRegisterDefaultImpl is now a public API, callers need
a way to invoke the default registered Handle and Timeout functions. We
already have general functions for these internally, so promote
them to the public API.

v2:
    Actually add APIs to libvirt.h

Removes special case code from the generator and handle additional
methods.

The generated version of remoteDispatchDomainPinVcpu(Flags) has no
length check, but this check was useless anyway as it was applied to
data that was already deserialized from its XDR form.

It was already generatable but skipped.

Even though rpc uses 'unsigned int' for the _len parameter that
passes the length of item<length>, the public libvirt APIs all
use 'int' and filter out lengths < 0, except for virDomainSendKey.

* include/libvirt/libvirt.h.in (virDomainSendKey): All other APIs
use int for array length.
* src/libvirt.c (virDomainSendKey): Adjust.
* src/driver.h (virDrvDomainSendKey): Likewise.
* daemon/remote_generator.pl: Likewise.

Commit 64000eab is part 1, that only covered the daemon side by
accident. Part 2 covers the client side too.

The position of the struct parameter in the function signature
differs. Instead of hardcoding the handling for this add an annotation
to the .x file to define the position.

When an operation started by virDomainBlockPullAll completes (either with
success or with failure), raise an event to indicate the final status.  This
allows an API user to avoid polling on virDomainBlockPullInfo if they would
prefer to use the event mechanism.

This patch implements the remote protocol for the new API
(virDomainPinVcpuFlags).

Detected by Coverity.  Commit ef21beda was incomplete; it solved
a leak one one path, but not on the other.

* daemon/libvirtd.c (qemudSetLogging): Avoid leak on success.

Detected by Coverity.  Only possible in OOM situations.

* daemon/remote.c (remoteDispatchDomainScreenshot): Plug leak.

Spotted by Coverity.  Only possible on an OOM condition, so
unlikely to bite in the wild.

* daemon/libvirtd.c (qemudSetLogging): Don't leak memory.

After successfull virDomainSave/virDomainManagedSave calls
the guest will no longer be active, so the domain ID must
be reset to -1

* daemon/remote_generator.pl: Special case virDomainSave &
  virDomainManagedSave for same reason as virDomainDestroy
