Add a new gdbarch method to print a single AUXV entry.
Different platforms have different meanings for auxiliary vector entries. The 'print_auxv_entry' gdbarch method allows an architecture to output a suitable description for platform-specific entries. A fprint_auxv_entry function is split out of fprint_target_auxv. This function outputs the description of a single auxiliary vector entry to the specified file using caller-supplied formatting and strings to describe the vector type. The existing switch on auxiliary vector types is moved out of fprint_target_auxv into a new default_print_auxv_entry function. default_print_auxv_entry chooses an appropriate format and description and calls fprint_single_auxv to describe a single vector entry. This function is used as the default 'print_auxv_entry' gdbarch method. fprint_target_auxv now invokes the gdbarch 'print_auxv_entry' method on each vector entry. gdb/ChangeLog: * auxv.c (fprint_auxv_entry): New function. (default_print_auxv_entry): New function. (fprint_target_auxv): Use gdbarch_print_auxv_entry. * auxv.h (enum auxv_format): New enum. (fprint_auxv_entry): Declare. (default_print_auxv_entry): Declare. * gdbarch.sh (print_auxv_entry): New. * gdbarch.c, gdbarch.h: Re-generated.
