initramfs-tools: merge debian v0.125

This bug was fixed in the package initramfs-tools - 0.125ubuntu1

---------------
initramfs-tools (0.125ubuntu1) yakkety; urgency=medium

  * Merge with debian 0.125 (LP: #1599915). Remaining delta:
   - Set takeover=1 in update-initramfs.
   - Drop hooks/keymap and associated code; console-setup takes care of
     this in Ubuntu.
   - Add a new 'fixrtc' script that tries to set the system clock forward
     based on the last mount time of the root disk; without this kludge,
     systems without a working RTC will end up in a perpetual reboot loop.
   - Set hostname at boot, for the benefit of mdadm autoassembly.
   - Ignore errors from iscan and iscan-data hooks.
   - Allow scripts and hooks to specify OPTION=VAR, and unless VAR is set
     to something other than "n", the script will not be included.
   - Restore the framebuffer hook and script, copying KMS and other
     framebuffer drivers into the initramfs, but make them optional; you
     need to set FRAMEBUFFER=y for these to be included.
   - Add hwaddr= alias for BOOTIF= for compatibility.
   - When receiving "recovery" on cmdline, start upstart with --startup-
     event=recovery (LP: #575469)
   - Make /etc/mtab a symlink to /proc/mounts on startup, since e.g.
     current ntfs-3g doesn't work otherwise.
   - Automatically blacklist vga16fb when vga= or video= specified on
     kernel command-line.
   - Add Hyper-V paravirtualised device drivers to the initramfs to allow
     booting of stock images in a Hyper-V guest. (LP: #917135)
   - Add mountroot failure support, to allow meaningful messages when no
     root device can be found.
   - Retain netboot= compatibility option.
   - Retain cryptopts= compatibility option.
   - Add vfat modules to the initramfs.
   - Maintain compatibility with pre- /run configurations
   - Increase rootdelay to 180s on powerpc/ppc64/ppc64el (LP: #1326199)
   - fixrtc: wait for udev to settle to expose device symlinks
   - fixrtc: handle hwclock -s failures safely
   - fixrtc: support busybox, handle last mount time on system partition,
     expose fs create time (LP: #1420473)
   - fixrtc: avoid using xargs, wait-for-root before examining
   - fixrtc: suppress /dev/ram as a root when using systempart (LP:
     #1443329)
   - ppc64el: enable PowerPC NX Crypto Coprocessor
   - resume: only resume when the partition contains a resume image
   - resume: announce resume via plymouth if available
   - Don't load keymaps unless we're loading a framebuffer; but set the
     keymap before giving a root shell.
   - Add new initramfs-tools-bin package containing a binary that uses
     libudev to wait for udev to create the udev device, or wait for udev
     to finish processing if we catch it in the act, and returns the
     filesystem type as already probed by udev.
   - Incorporate rzscontrol from compcache so that we can control current
     ramzswap devices.
   - Support loading compcache from the initramfs.
   - debian/control: update Vcs-* links for Ubuntu.
   - hook-functions: fix PowerPC NX Crypto Coprocessor support (LP:
     #1454687)
   - Drop: Maintain compatibility with pre- /run configurations (LP:
     #1485752)
   - Drop: Ignore errors from ...
