Add "inferior" argument to some target_fileio functions

This commit adds a new argument to all target_fileio functions with
filename arguments to allow the desired inferior to be specified.
This allows GDB to support systems where processes do not necessarily
share a common filesystem.

gdb/ChangeLog:

	* target.h (struct inferior): New forward declaration.
	(struct target_ops) <to_filesystem_is_local>: Update comment.
	(struct target_ops) <to_fileio_open>: New argument inf.
	Update comment.  All implementations updated.
	(struct target_ops) <to_fileio_unlink>: Likewise.
	(struct target_ops) <to_fileio_readlink>: Likewise.
	(target_filesystem_is_local): Update comment.
	(target_fileio_open): New argument inf.  Update comment.
	(target_fileio_unlink): Likewise.
	(target_fileio_readlink): Likewise.
	(target_fileio_read_alloc): Likewise.
	(target_fileio_read_stralloc): Likewise.
	* target.c (target_fileio_open): New argument inf.
	Pass inf to implementation.  Update debug printing.
	(target_fileio_unlink): Likewise.
	(target_fileio_readlink): Likewise.
	(target_fileio_read_alloc_1): New argument inf. Pass inf
