hsize and vsize

[Werner LEMBERG]

Any reason why `hsize' and `vsize' are defined in lilypond's init
files?  They are completely useless.  I even go one step further:
Noone needs paper init files like `a4-init.ly'.  Currently, lilypond
needs a single paper dimension, namely `linewidth'.  In the future, it
will probably need `textheight' also to find proper page breaks.

What do you think about getting rid of this old stuff, creating a
`lilyrc' file (and a user-specific `.lilyrc') which contains a proper

  linewidth = ...

entry (to be overridden in a .ly file)?
