ui/sdl: Fix handling of caps lock and num lock keys
Starting with SDL version 1.2.14, caps lock and num lock keys
will send a SDL_KEYUP when SDL_DISABLE_LOCK_KEYS=1 is set in
the environment.
The new code sets the environment unconditionally
(it won't harm old versions which do not know it).
The workaround for SDL_KEYUP is only compiled with old SDL versions.
A similar patch without handling of old SDL versions was already

vnc: Fix password expiration through 'change vnc ""' (v2)
commit
52c18be9e99dabe295321153fda7fce9f76647ac introduced a regression in the
change vnc password command that changed the behavior of setting the VNC
password to an empty string from disabling login to disabling authentication.
This commit refactors the code to eliminate this overloaded semantics in
vnc_display_password and instead introduces the vnc_display_disable_login. The
monitor implementation then determines the behavior of an empty or missing
string.
Recently, a set_password command was added that allows both the Spice and VNC
password to be set. This command has not shown up in a release yet so the
behavior is not yet defined.
This patch proposes that an empty password be treated as an empty password with
no special handling. For specifically disabling login, I believe a new command
should be introduced instead of overloading semantics.
I'm not sure how Spice handles this but I would recommend that we have Spice
and VNC have consistent semantics here for the 0.14.0 release.

Segmentation fault (core dumped)
add_init_drive() is confused about drive_init()'s failure modes, and
cleans up when it shouldn't. This leaves the DriveInfo with member
opts dangling. drive_del attempts to free it, and dies.
drive_init() behaves as follows:
* If it created a drive with media, it returns its DriveInfo.
* If it created a drive without media, it clears *fatal_error and
returns NULL.
* If it couldn't create a drive, it sets *fatal_error and returns
NULL.
Of its three callers:
* drive_init_func() is correct.
* usb_msd_init() assumes drive_init() failed when it returns NULL.
This is correct only because it always passes option "file", and
"drive without media" can't happen then.
* add_init_drive() assumes drive_init() failed when it returns NULL.
This is incorrect.
Clean up drive_init() to return NULL on failure and only on failure.
