Fix handling of package-db entries in .ghc.environment files, etc.
Previously interpreting the content of the .ghc.env files was done after the step that loaded the available package dbs. This meant that setting the package db flags was ineffective. This patch moves interpreting the env files before loading of the package dbs. Also, the package-db entries refer to files. Allow spaces in these file names. Also treat as comments lines beginning with "--". These are pretty minor fixes in a feature that up 'til now has been essentially unused (witness no bug report about it), so there's very low risk here. If we can get this into 8.0.2 then cabal can start generating the .ghc.environment files, otherwise it cannot as it needs the working package-db entries, to be able to refer to local package dbs in the build tree (or cabal nix store). Test Plan: Manually create example .ghc.env files run ghci; :show packages Done this. It works.
