[bash] Define dotfiles.

Shells are command line interpreter for UNIX systems. These shells can
operate in one of three modes: interactive, non-interactive or
login. Login mode starts with a login prompt. After that it works
similarly to either interactive or non-interactive mode.

~/.bash_profile is the dotfile for bash in the login mode. It sources
program-specific *.sh profiles in {XDG_CONFIG_HOME}/profile.d. This
mimics behaviour of /etc/profile, the global shell dotfile.

~/,bashrc is the dotfile for bash in the interactive mode.
