ubi-utils: allow 'ubiformat' to read from stdin

This patch allows to read the image from stdin and adds an
'--image-size' option to specify its size.  'upiupdatevol' has this
feature already and it is useful for 'ubiformat' too.

It adds a read_all() function which reads a block of data. Plain
'read(2)' can fail on

  nc -l -p 1234 | ubiformat -f - -S 25427968

else.
