initramfs cryptroot usplash support

[Alexander Malysh]

Binary package hint: cryptsetup

Attached patch against cryptsetup-2:1.0.4+svn26-1ubuntu1 fixes two issues:
1) we should wait at least 10sec for cryptsource device to appear. This is for example needed on my laptop with SATA.
2) don't quite usplash because new version has possibility to get password from user

Please review and commit.

Thanks for the patch. Does this still apply against cryptsetup 2:1.0.4+svn29-1ubuntu4? I've added the patch tag to draw the attention of packagers. I have unsubscribed ubuntu-universe-sponsors, as this does not represent a nre revision candidate (patch is not a debdiff). If the patch applies, and a debdiff is generated for this issue, please resubscribe ubuntu-universe-sponsors to request upload.

2:1.0.5-1ubuntu1 no longer quits usplash and correctly accepts a password while it's running, but the other status messages are only echod to the console (success, failure). Those should be written to the usplash box as well.
