Philippe Waroquiers 3f4d92ebdf Fix the problems reported by prefix check of command-def-selftests.c
The next commit updates command-def-selftests.c to detect missing
or wrong prefix commands in a list of subcommands.
This command structure selftest detects a series of problems
that are fixed by this commit.

Many commands have a null prefix command, e.g.
    (gdb) maintenance selftest command_str
    Running selftest command_structure_invariants.
    list 0x560417949cb8 reachable via prefix 'append binary '.  command 'memory' has null prefixcmd
    list 0x560417949cb8 reachable via prefix 'append binary '.  command 'value' has null prefixcmd
    ...

Most of these are fixed by the following changes:
  * do_add_cmd searches the prefix command having the list
    in which the command is added.
    This ensures that a command defined after its prefix command
    gets the correct prefix command.
  * Due to the GDB initialization order, a GDB file can define
    a subcommand before the prefix command is defined.
    So, have add_prefix_cmd calling a new recursive function
    'update_prefix_field_of_prefix_commands' to set the prefix
    command of all sub-commands that are now reachable from
    this newly defined prefix command.  Note that this recursive
    call replaces the function 'set_prefix_cmd' that was providing
    a partial solution to this problem.

Following that, 2 python commands (defined after all the other GDB
commands) got a wrong prefix command, e.g. "info frame-filter" has
as prefix command the "i" alias of "info".  This is fixed by having
lookup_cmd_for_prefixlist returning the aliased command rather than
the alias.

After that, one remaining problem:
    (gdb) maintenance selftest command_str
    Running selftest command_structure_invariants.
    list 0x55f320272298 reachable via prefix 'set remote '.  command 'system-call-allowed' has null prefixcmd
    Self test failed: self-test failed at ../../classfix/gdb/unittests/command-def-selftests.c:196
    Ran 1 unit tests, 1 failed
    (gdb)

Caused by initialize_remote_fileio that was taking the address of
its arguments remote_set_cmdlist and remote_show_cmdlist instead
of receiving the correct values to use as list.

	* cli/cli-decode.c (lookup_cmd_for_prefix): Return the aliased command
	as prefix, not one of its aliases.
	(set_cmd_prefix): Remove.
	(do_add_cmd): Centralize the setting of the prefix of a command, when
	command is defined after its full chain of prefix commands.
	(add_alias_cmd): Remove call to set_cmd_prefix, as do_add_cmd does it.
	(add_setshow_cmd_full): Likewise.
	(update_prefix_field_of_prefixed_commands): New function.
	(add_prefix_cmd): Replace non working call to set_cmd_prefix by
	update_prefix_field_of_prefixed_commands.
	* gdb/remote-fileio.c (initialize_remote_fileio): Use the real
	addresses of remote_set_cmdlist and remote_show_cmdlist given
	as argument, not the address of an argument.
	* gdb/remote-fileio.h (initialize_remote_fileio): Likewise.
	* gdb/remote.c (_initialize_remote): Likewise.

README

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
