fallocate: new command
The fallocate(1) utility is used to preallocate blocks to a file.
This can be useful for virtual images, database files, testing, etc.
Normally we'd hope that various tools will start using preallocation
internally, but until then such a utility may be useful, and could be
scripted as well.
The original Eric's version is available at:
http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/2490
This version:
- checks for fallocate glibc function and kernel syscall
- does not provide a fallback and does not call posix_fallocate()
- adds long options
- uses err.h for errro messages
- adds NLS support
- cleanups man page
