RFC: [PATCH] Simplify installed.db format

[Igor Peshansky <pechtcha at cs dot nyu dot edu>]

Hi,

The current format for installed.db is (except the first line)

PKG-NAME TARBALL-NAME 0

which setup tries to parse as

package-name filename filesize src-filename srcsize

(with src-filename and srcsize never used, and the filesize field never
accessed).  I propose to remove the unused fields, with the intention of
later reusing the (always 0) for something else.

The attached patch fixes the parsing of installed.db package lines.
Comments welcome.
	Igor
