bug #34302: Feature request : device configuration with parent classes

Browse Source 
* config_gram.y: if memory section is overwritten old entry is removed
        
(not in original patch)
* config_gram.y: if programmer or part is defined twice, a warning is
  output and the first instance is removed
        
General cleanup and free functions, so valgrind does not report any lost
blocks at program end.
* avrpart.[hc]: added avr_free_(opcode|mem|part) functions
* pgm.[hc]: added pgm_free function
* update.[hc]: added free_update functions
* config.[hc]: added cleanup_config function, use yylex_destroy to reset
  the lexer after usage. (So it can be reused.)
* main.c: add cleanup_main function which is called by atexit() (This 
  frees all lists so that at program exit only really lost memory is 
  reported by valgrind.)
* usbasp.c: added libusb_free_device_list() and libusb_exit() calls to
  avoid lost memory
* buspirate.c: moved memory allocation from initpgm to setup and added 
  free in teardown
* configure.ac: add definition of HAVE_YYLEX_DESTROY if $LEX is flex.
* Makefile.am: added . in front of SUBDIRS to build avrdude before trying
  to use it for creating the part list for the docs.
