Deb package consistency tweaks

Changes to the various deb files to be consistent with an installed foundationdb-server. This includes user name, directories, owner, permissions and file names. Additionally, stop signing as the server packages aren't (on purpose). While there, fix relevant Lintian warnings and rewrite init script based off the /etc/init.d/skeleton for standard compliance with less custom portions.

Other changes:
- Wrap Main.main() work in try/catch and output to logger. Eliminates need for server_stdout.log
- Change FDBSQL_HOME of fdbsqlparser to an command line argument
- Change log file name to layer.log
- Add text.indexpath to properties file so it isn't going to /tmp on real installs
- Tweak test paths of the data, text and log for consistency
- Remove -Xss from jvm.options as a recent JRE (tested with 1.7.0_40) has a 288 min and it seems to be a moving target

Note: Includes services-config-optional branch.
