Destroying a mutex that another thread might have just unlocked
is racy.  It usually works, but you cannot do that in general and
can lead to deadlocks or segfaults.  Change ccid to use joinable
threads instead.

(Also, qemu_mutex_init/qemu_cond_init were missing).

Rewrite the handshaking between qemu_thread_create and the
win32_start_routine, so that the thread can be joined without races.
Similar handshaking is done now between qemu_thread_exit and
qemu_thread_join.

This also simplifies how QemuThreads are initialized.

Allow to control if a QEMU thread is created joinable or not. Make it
not joinable by default to avoid that we keep the associated resources
around when terminating a thread without joining it (what we couldn't do
so far for obvious reasons).

The audio subsystem will need the join feature when converting it to
QEMU threading/locking abstractions, so provide that service.

Today net/socket.c has no consistent policy for closing the socket file
descriptor when initialization fails.  This means we leak the file
descriptor in some cases or we could also try to close it twice.

Make error paths consistent by taking ownership of the file descriptor
and closing it on error.

Not that there is blacklisting functionality we can no longer infer
the agent's capabilities via version. This patch extends the current
guest-info RPC to also return a list of dictionaries containing the name
of each supported RPC, along with a boolean indicating whether or not
the command has been disabled by a guest administrator/distro.

This adds a command-line option, -b/--blacklist, that accepts a
comma-seperated list of RPCs to disable, or prints a list of
available RPCs if passed "?".

In consequence this also adds general blacklisting and RPC listing
facilities to the new QMP dispatch/registry facilities, should the
QMP monitor ever have a need for such a thing.

Ideally, to avoid support/compatability issues in the future,
blacklisting guest agent functionality will be the exceptional
case, but we add the functionality here to handle guest administrators
with specific requirements.

All qemu_fclose() callers were already changed to accept any negative

This will make sure no error will be missed as long as callers always
check for qemu_fclose() return value. For reference, this is the
complete list of qemu_fclose() callers:

 - exec_close(): already fixed to check for negative values, not -1
 - migrate_fd_cleanup(): already fixed to consider only negative values
   as error, not any non-zero value
 - exec_accept_incoming_migration(): no return value check (yet)
 - fd_accept_incoming_migration(): no return value check (yet)
 - tcp_accept_incoming_migration(): no return value check (yet)
 - unix_accept_incoming_migration(): no return value check (yet)
 - do_savevm(): no return value check (yet)
 - load_vmstate(): no return value check (yet)

Also, we now return the qemu_fclose() value unchanged to the caller. For
reference, the migrate_fd_cleanup() callers are the following:

- migrate_fd_completed(): any negative value is considered an
  error, so the change is OK.
- migrate_fd_error(): doesn't check the migrate_fd_cleanup() return value
- migrate_fd_cancel(): doesn't check the migrate_fd_cleanup() return
  value

qemu_fclose() and QEMUFile->close will return -errno on error, and any
positive value on success.

We need the positive non-zero success values because
migration-exec.c:exec_close() relies on non-zero return values to get
the process exit code.
