Subject: vhdx: Use QEMU UUID API
X-Git-Tag: TizenStudio_2.0_p2.3.2~9^2~14^2~5^2~170^2~19
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cb6414dfec8a308e68529b0fd2a454403c05bbb3;p=sdk%2Femulator%2Fqemu.git

vhdx: Use QEMU UUID API

This removes our dependency to libuuid, so that the driver can always be
built.

Similar to how we handled data plane configure options, --enable-vhdx
and --disable-vhdx are also changed to a nop with a message saying it's
obsolete.
