Add the support of capability to makedevs as extended attribute.
Now, it's possible to add a line "|xattr <capability>" after a
file description to also add a capability to this file. It's
possible to add severals capabilities with severals lines.

Currently, makedevs will query the host's /etc/passwd and /etc/group to
resolve usernames and group names. This is inherently flawed, as we can
never guarantee that the UIDs will be the same on the target as on the
host, or even whether a particular user does exist on the host.
This is because getpwnam() and getgrnam() will forcibly read the
system's /etc/passwd and /etc/group, and there is no way to tell them to
look anywhere else.
However, we can use fgetpwent() and fgetgrent() instead, for which
we can pass a FILE* stream to read from to get the entries. This means
we must implement the scanning-loop ourselves, but fortunately, that's
pretty trivial to do.

There's no real reason to sync after creating the device nodes,
and it slows down the file system image creating quite a lot on
busy systems, so get rid of it.

The makedevs script did not always generate the requested set of device names / minor number series.
* If start != 0, then requesting (count) devices would generate only (count - start)
* If start != 0 && increment != 1, then requesting minors starting with (minor) would generate minors starting with (minor + (start * (increment - 1)))
This patch fixes the code and updates the usage text with extra examples.
