Introduce GIT_DIR environment variable.
During the mailing list discussion on renaming GIT_ environment variables, people felt that having one environment that lets the user (or Porcelain) specify both SHA1_FILE_DIRECTORY (now GIT_OBJECT_DIRECTORY) and GIT_INDEX_FILE for the default layout would be handy. This change introduces GIT_DIR environment variable, from which the defaults for GIT_INDEX_FILE and GIT_OBJECT_DIRECTORY are derived. When GIT_DIR is not defined, it defaults to ".git". GIT_INDEX_FILE defaults to "$GIT_DIR/index" and GIT_OBJECT_DIRECTORY defaults to "$GIT_DIR/objects". Special thanks for ideas and discussions go to Petr Baudis and Daniel Barkalow. Bugs are mine ;-) Signed-off-by: Junio C Hamano <junkio@cox.net>
