Makefile overhaul

* added a "help" target
* moved pydoc creation to Makefile (bin/build/do_pydoc.sh no longer necessary)
* moved html doc creation to Makefile (allows parallelization)
* support parallel deprules compression (_compress-deprules)
* enforce file/dir mode for all installed files
  (use recursive "install", not "cp -r")
* "dist" target: compress with bzip2, gzip and xz, depending on
  X_BZIP2, X_GZIP, X_XZ
* removed broken "install-roverlay" target
* "install-pymodules" renamed to "install" as it installs
  scripts/binaries as well
* "install-config-compressed" dropped in favor of COMPRESSED_CONFIG=0|1
  (in "install-config")
* added "install-bashcomp", "install-nonpy"
* removed uninstall-roverlay, renamed uninstall-pymodules->uninstall

These changes are incompatible with the current roverlay-9999.ebuild's
src_install().
