Tom Tromey 3cd5229387 Change the pager to a ui_file
This rewrites the output pager as a ui_file implementation.

A new header is introduced to declare the pager class.  The
implementation remains in utils.c for the time being, because there
are some static globals there that must be used by this code.  (This
could be cleaned up at some future date.)

I went through all the text output in gdb to ensure that this change
should be ok.  There are a few cases:

* Any existing call to printf_unfiltered is required to be avoid the
  pager.  This is ensured directly in the implementation.

* All remaining calls to the f*_unfiltered functions -- the ones that
  take an explicit ui_file -- either send to an unfiltered stream
  (e.g., gdb_stderr), which is obviously ok; or conditionally send to
  gdb_stdout

  I investigated all such calls by searching for:

    grep -e '\bf[a-z0-9_]*_unfiltered' *.[chyl] */*.[ch] | grep -v gdb_stdlog | grep -v gdb_stderr

  This yields a number of candidates to check.

  * The breakpoint _print_recreate family, and
    save_trace_state_variables.  These are used for "save" commands
    and so are fine.

  * Things printing to a temporary stream.  Obviously ok.

  * Disassembly selftests.

  * print_gdb_help - this is non-obvious, but ok because paging isn't
    yet enabled at this point during startup.

  * serial.c - doens't use gdb_stdout

  * The code in compile/.  This is all printing to a file.

  * DWARF DIE dumping - doesn't reference gdb_stdout.

* Calls to the _filtered form -- these are all clearly ok, because if
  they are using gdb_stdout, then filtering will still apply; and if
  not, then filtering never applied and still will not.

Therefore, at this point, there is no longer any distinction between
all the other _filtered and _unfiltered calls, and they can be
unified.

In this patch, take special note of the vfprintf_maybe_filtered and
ui_file::vprintf change.  This is one instance of the above idea,
erasing the distinction between filtered and unfiltered -- in this
part of the change, the "unfiltered_output" flag is never passe to
cli_ui_out.  Subsequent patches will go much further in this
direction.

Also note the can_emit_style_escape changes in ui-file.c.  Checking
against gdb_stdout or gdb_stderr was always a bit of a hack; and now
it is no longer needed, because this is decision can be more fully
delegated to the particular ui_file implementation.

ui_file::can_page is removed, because this patch removed the only call
to it.

I think this is the main part of fixing PR cli/7234.

		   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.
