Andrew Burgess 19cf757a87 gdb: spread a little 'const' through the target_section_table code 
The code to access the target section table can be made more const, so
lets do that.  There should be no user visible changes after this
commit.

gdb/ChangeLog:

	* gdb/bfd-target.c (class target_bfd) <get_section_table>: Make
	return type const.
	* gdb/exec.c (struct exec_target) <get_section_table>: Likewise.
	(section_table_read_available_memory): Make local const.
	(exec_target::xfer_partial): Make local const.
	(print_section_info): Make parameter const.
	* gdb/exec.h (print_section_info): Likewise.
	* gdb/ppc64-tdep.c (ppc64_convert_from_func_ptr_addr): Make local
	const.
	* gdb/record-btrace.c (record_btrace_target::xfer_partial):
	Likewise.
	* gdb/remote.c (remote_target::remote_xfer_live_readonly_partial):
	Likewise.
	* gdb/s390-tdep.c (s390_load): Likewise.
	* gdb/solib-dsbt.c (scan_dyntag): Likewise.
	* gdb/solib-svr4.c (scan_dyntag): Likewise.
	* gdb/target-debug.h (target_debug_print_target_section_table_p):
	Rename to...
	(target_debug_print_const_target_section_table_p): ...this.
	* gdb/target-delegates.c: Regenerate.
	* gdb/target.c (target_get_section_table): Make return type const.
	(target_section_by_addr): Likewise.  Also make some locals const.
	(memory_xfer_partial_1): Make some locals const.
	* gdb/target.h (struct target_ops) <get_section_table>: Make
	return type const.
	(target_section_by_addr): Likewise.
	(target_get_section_table): Likewise.

#ifndef TARGET_DEBUG_H
#define TARGET_DEBUG_H
/* Printers for the debug target. Each prints an object of a given
type to a string that needn't be freed. Most printers are macros,
for brevity, but a few are static functions where more complicated
behavior is needed.
References to these printers are automatically generated by
make-target-delegates. See the generated file target-delegates.c.
In a couple cases, a special printing function is defined and then
used via the TARGET_DEBUG_PRINTER macro. See target.h.
A few methods still have some explicit targetdebug code in
target.c. In most cases this is because target delegation hasn't
been done for the method; but individual cases vary. For instance,
target_store_registers does some special register printing that is
more simply done there, and target_xfer_partial additionally
bypasses the debug target. */
