fc96358cdd truncate: Detect integer overflow, fix relative sizes, add tests.
The change to expand_number (r204654) broke detection of too large sizes and
relative sizes ('+'/'-').

Also add some tests.

human-friendly power-of-two numbers (i.e. 2k, 5M etc).

5eccbe45a7 The -r option can also cause the files to be extended (not
necessarily truncated).

a39846b5e4 o Don't leak fd on error.
o parselength() returns 0 or -1 so int is enough for its return type.

e6f3621dd3 Allow to specify size in terabytes by using T or t suffix.
This speeds up my testing a bit. Because truncate(1) doesn't allocate
blocks on file system before they are used, it is very useful to
emulate huge file systems:

	# truncate -s 16T fs.img
	# mdconfig -a -f fs.img
	# newfs /dev/mdX

(-t swap can be used as well)
