block/vvfat: Plug memory leak in enable_write_target()

I figure the leak originated in bdrv_create2(), and was duplicated
into callers when commit 91a073a dropped that function.  Looks like
the other places have since been fixed.

qemu-io: Support multiple -o in open command

Instead of ignoring all option values but the last one, multiple -o
options now have the same meaning as having a single option with all
settings in the order of their respective -o options.

Same as commit 2dc8328 for qemu-img convert, except here we do it with
QemuOpts rather than QEMUOptionParameter.

blockdev: Plug memory leak in blockdev_init()

blockdev_init() leaks bs_opts when qemu_opts_create() fails, i.e. when

blockdev: Plug memory leak in drive_init()

bs_opts is leaked on all paths from its qdev_new() that don't got
through blockdev_init().  Add the missing QDECREF(), and zap bs_opts
after blockdev_init(), so the new QDECREF() does nothing when we go
through blockdev_init().

block/raw-posix.c: Avoid nonstandard LONG_LONG_MAX

In the MacOSX specific code in raw-posix.c we use the define
LONG_LONG_MAX. This is actually a non-standard pre-C99 define;
switch to using the standard LLONG_MAX instead.

This apparently fixes a compilation failure with certain
compiler/OS versions (though it is unclear which).

qemu-img: Report error even with --oformat=json

img_check() should report that the format of the given image does not
support checks even if JSON output is desired. JSON data is output to
stdout, as opposed to error messages, which are (in the case of
qemu-img) printed to stderr. Therefore, it is easy to distinguish
between the two.

Also, img_info() does already use error_report() for human-readable
messages even though JSON output is desired (through
collect_image_info_list()).

Revert "bsd-user: replace fprintf(stderr, ...) with error_report()"

This reverts commit 1fba509527beb74bdcf50bc07ad3cd8244ad9c61.

That commit converted various fprintf(stderr, ...) calls to
use error_report(); however none of these bsd-user files include
a header which gives a prototype for error_report, so this
causes compiler warnings. Since these are just straightforward
reporting of command line errors, we should handle these in the
obvious way by printing to stderr, as we do for linux-user.
There's no need to drag in the error-handling framework for this,
especially since user-mode doesn't have the "maybe we need to
send this to the monitor" issues system emulation does.

vnc: refuse to set a password with VNC_AUTH_NONE

Current code silently changes the authentication settings
in case you try to set a password without password authentication
turned on.  This is bad.  Return an error instead.

If we want allow changing auth settings at runtime this should
be done explicitly using a separate monitor command, not as
side effect of set_passwd.
