* remote-fileio.c: New file implementing the remote File-I/O protocol.
* remote-fileio.h: New header file defining remote File-I/O interface.
* remote.c (remote_write_bytes, remote_read_bytes): Remove
static storage class.
(remote_wait, remote_async_wait): Call remote_fileio_request() on
'F' packet.
(_initialize_remote): Call initialize_remote_fileio().
* remote.h: Declare remote_write_bytes() and remote_read_bytes().
* Makefile.in (REMOTE_OBS): Add remote-fileio.o
(SFILES): Add remote-fileio.c.
Add dependencies for building remote-fileio.o. Add remote-fileio.h to
dependencies for building remote.o.
* defs.h: Declare gdb_stdin, gdb_stdtargerr and gdb_stdtargin.
* main.c: New ui_file gdb_stdin, gdb_stdtargerr and gdb_stdtargin.
(captured_main): Initialize new ui_files.
* ui-file.c: Add read and fgets input functions.
(ui_file_new): set ui_file_fputs and ui_file_read to null functions.
(null_file_read): New function.
(ui_file_read): New function.
(set_ui_file_read): New function.
(stdio_file_read): New function.
* ui-file.h: New type ui_file_read_ftype.
(set_ui_file_read): Declare.
(ui_file_read): Declare.
* ui-file.c: Include "gdb_string.h"
* cli-out.c: Include gdb_string.h to avoid compiler warnings.
* wrapper.[ch] (struct gdb_wrapper_arguments): Change fields into
unions, since they are all used to hold both pointers and ints
at various times. Casting pointer to int and vice versa gives
warnings (and is not safe) if they are not the same size.
