No, none.

Yes, seems to be in many distribution buildscripts.
Seems maintainers by reflex think udev is installed, that they
want it themselfs, or that it provides some convenience that shouldn't
be left out.

Since it's funtoo (which is based on gentoo): everything.

By modifying the funtoo build script, removing mentions of udev:

$ cd /usr/portage
$ diff ./x11-drivers/xf86-input-evdev/xf86-input-evdev-2.9.2.ebuild*
10c10
< RDEPEND=">=x11-base/xorg-server-1.12
---
> RDEPEND=">=x11-base/xorg-server-1.12[udev]
$ diff x11-base/xorg-server/old/xorg-server-1.16.4-r1.ebuild x11-base/xorg-server/xorg-server-1.16.4-r1.ebuild
12c12
< IUSE="dmx kdrive xnest +xorg xvfb glamor ipv6 minimal nptl selinux +suid systemd tslib +udev unwind wayland"
---
> IUSE="dmx kdrive xnest +xorg xvfb glamor ipv6 minimal nptl selinux +suid systemd tslib unwind wayland"

<       udev? ( >=virtual/udev-150 )
170d168
<               $(use_enable udev config-udev)
$

and then

# emerge --regen

I don't remeber if I had to do anything with mesa. In mesa there is:

$ git remote -v
origin  git://anongit.freedesktop.org/git/mesa/mesa (fetch)
origin  git://anongit.freedesktop.org/git/mesa/mesa (push)
$ ./configure --help | grep sysfs
  --enable-sysfs          enable /sys PCI identification [default=disabled]
$

which you can use instead of libudev.

///

If you run current xorg server, you have to make your own xorg.conf (I
think). I added flag below to make it work:

Section "ServerFlags"
...
        Option "AutoAddDevices" "off"
EndSection
