Patch from Tito:

Remove -v verbose -V version -q quiet flags
Remove parse_opt_v2();
Rename parse_opt_v3() to parse_xfermode()
Remove if_strcat()
Rearrange code in  dump_identity() to reduce size
Modify some strings so that they could be optimized by the compiler
Minor code clean up
Remove unneeded #define <shm.h>

#if BB_BIG_ENDIAN && !defined(__USE_XOPEN)
# define __USE_XOPEN
#endif    
Must be before #include <unistd.h> and #include "busybox.h"
(noticed by Bernhard Fischer <rep.nop@aon.at>)

Remove duplicate code in do_time()
