[RFA] Ensure GDB warnings are styled.

While handling the comments of Tom related to
[RFC] Have an option to tell GDB to detect and possibly handle mismatched exec-files.
https://sourceware.org/ml/gdb-patches/2019-12/msg00621.html
I saw that GDB warnings are produced ignoring the given styles.
This patch:
* ensures that style markups are properly handled by "warning".
* changes 'set/show data-directory' so that file style is used
in warnings and in 'show message'
* changes all other messages in top.c to use file style when appropriate.
* Uses the above data-directory changes in gdb.base/style.exp
2019-12-15 Philippe Waroquiers <philippe.waroquiers@skynet.be>
* ui-file.c (stdio_file::can_emit_style_escape)
(tee_file::can_emit_style_escape): Ensure style is used also on
gdb_stderr when gdb_stderr is a tty supporting styling, similarly
to gdb_stdout.
* main.c (set_gdb_data_directory): Use file style to output the
warning that the given pathname is not a directory.
* top.c (show_history_filename, gdb_safe_append_history)
(show_gdb_datadir): Use file style.
2019-12-15 Philippe Waroquiers <philippe.waroquiers@skynet.be>
* gdb.base/style.exp: Test that warnings are styled.
