Some gdb.dwarf2/*.exp tests copy file1.txt to host via gdb_remote_download
but dw2-filename.exp and dw2-anonymous-func.exp don't do that. Looks like
an oversight in this patch
https://sourceware.org/ml/gdb-patches/2013-08/msg00365.html
There are some fails in remote host testing.
FAIL: gdb.dwarf2/dw2-anonymous-func.exp: list file1.txt
FAIL: gdb.dwarf2/dw2-filename.exp: interpreter-exec mi -file-list-exec-source-files
FAIL: gdb.dwarf2/dw2-filename.exp: info sources
This patch is to invoke gdb_remote_download to copy file1.txt to host
and remote it at the end. This patch fixes these fails above.

Pierre proposed this patch
https://sourceware.org/ml/gdb-patches/2013-10/msg00011.html and
Tom gave a suggestion that it's better to do check \t in print_wchar
<https://sourceware.org/ml/gdb-patches/2013-11/msg00148.html>
However, I don't see the follow-up to this discussion.
We encounter two fails in printcmds.exp on mingw host, and Pierre's
patch fixes them. I pick it up, update a little per Tom's
comments, and post it here for review. This patch fixes these fails
below on mingw32 host.

Since we're not compiling with gcc, we don't know where the

testsuite/outputs/gdb.dwarf2/foo (parallel mode).

I happened to notice that print_macro_definition is indented

* macrocmd.c (print_macro_definition): Reindent.
This patch fixes mi-file.exp fails on remote host. First, we can't
assume ${srcdir}/${subdir}/${srcfile} directory exists on remote host,
so this patch changes it to match ${srcfile} only on remote host.
Second, regexp pattern ".*/${srcfile}" isn't friendly to Windows path.
The file name is "basics.c" in my test env and can't match the pattern
due to "/" in it. Remove "/" from the pattern.

After I run test like this,
$ make check RUNTESTFLAGS='--host_board=local-remote-host dw2-basic.exp'
gdb.dwarf2/file1.txt in source tree was removed. In some gdb.dwarf2/*.exp,
file1.txt is copied to host and then removed at the end. However, in
local-remote-host-notty.exp, ${board}_download doesn't copy the file but
return the absolute path of the src file. 'remote_file host delete' at
the end will remove the file in source tree.
This patch is to overwrite ${board}_file, and specially make "delete"
option do nothing. This approach is used in gdbserver-base.exp and
remote-stdio-gdbserver.exp too.

to access a global as it expects a GOTPCREL relocation. This is really not
necessary as the linker could use a copy relocation to get around it. This
patch enables copy relocations with pie.
Context:
This is useful because currently the GCC compiler with option -fpie makes
every extern global access go through the GOT. That is because the compiler
cannot tell if a global will end up being defined in the executable or not
and is conservative. This ends up hurting performance when the binary is linked
as mostly static where most of the globals do end up being defined in the
executable. By allowing copy relocs with fPIE, the compiler need not generate
a GOTPCREL(GOT access) for any global access. It can safely assume that all
globals will be defined in the executable and generate a PC-relative access
instead. Gold can then create a copy reloc for only the undefined globals.

In mi_interpreter_init, multiple MI consoles/channels are created and a quoting
character is given. In mi_console_raw_packet, we check if the value is not 0
to decide if we should quote the string, but we don't use the value. It is
hardcoded to ". We might never use another quoting character than an actual
quote, but I suggest we change it, for correctness. There is not visible
behavior change.
I changed the latest fputs_unfiltered changed to fputc_unfiltered just to stay
consistent.
