[PATCH RFC 0/3] mke2fs: small doc and features

[Ralph Siemsen <ralph.siemsen@linaro.org>]

Three independent fixes for mke2fs:

1) document the hash_seed option
2) prohibit multiple '-E' arguments 
3) add extended option for setting root inode security context

The first fix is straightforward.

For the second one, some alternatives would be:
- only print a warning, not a fatal error (but that is easy to miss)
- allow multiple '-E' options, and join them automatically

For the third one, the main use case is when generating empty
filesystems for use when SELinux is enabled.
