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.
