From: Steve Reinhardt <stever@eecs.umich.edu>

Subject: New ini-file feature: += appends RHS to LHS. Added doxygen comments
 to inifile.hh. Updated initest.  Some other minor cleanup.

base/inifile.cc:
    Add support for '+=' append operation.
    Factor common code from IniFile::load() and IniFile::add() into new Section::add().
    Rename ConfigTable to SectionTable (more descriptive).
    Fix bug in Section::dump().
base/inifile.hh:
    Add doxygen comments.
    Add support for '+=' append operation.
    Factor common code from IniFile::load() and IniFile::add() into new Section::add().
    Rename ConfigTable to SectionTable (more descriptive).
test/Makefile:
    initest needs cprintf.o now.
test/foo.ini:
    Add test of '+=' operator.
test/initest.cc:
    Bring this up-to-date.  Steal main loop from main.cc so we can test
    multiple .ini files and command-line assignments too.
