Some gdb.guile tests such as scm-error.exp copies .scm file to
${subdir}/, how ${subdir} doesn't exist in parallel testing
(outputs/${subdir} exists).

This patch is to remove the third argument of gdb_remote_download, so
that gdb_remote_download can return the correct location.
Further, these tests only copy .scm files to a different name. From what
I can tell from the comments, looks we do this to avoid clobbering file
in in-tree build. However, if source and dest of copy are the same, the
operation is no-op. So it makes few sense to copy .scm files to a
different names. I tried in-tree build/test with this patch, test
result isn't changed.

I see the following two fails on arm-none-eabi target, because argv[0]
isn't available.
print argv[0]^M
$1 = 0x1f78 "/dev/null"^M
(gdb) FAIL: gdb.base/argv0-symlink.exp: kept file symbolic link name
print argv[0]^M
$1 = 0x1f78 "/dev/null"^M
(gdb) FAIL: gdb.base/argv0-symlink.exp: kept directory symbolic link name
My first thought is to check [target_info exists noargs], and skip the
test if it returns true. However, noargs is set in gdbserver board
files, so argv0-symlink.exp will be skipped on gdbserver board file.
The change is too aggressive.
When the program is running with gdbserver, argv[1] to argv[N] aren't
available, but argv[0] is. Fortunately, argv0-symlink.exp only
requires argv[0]. argv0-symlink.exp can be run with gdbserver board
file, as what we do now.
What we need to check is whether argv[0] is available, so I add a new
proc gdb_has_argv0 to do so by starting a program, and check
argc/argv[0] to see whether argv[0] is available.
Dan fixed the similar problem by checking noargs, which is too strong.
https://sourceware.org/ml/gdb-patches/2010-02/msg00398.html as a
result, the test is skipped on gdbserver. This patch fixed it too.

Some testcases, mostly gdb.reverse ones, assume the presence of a
'/' directory separator before the source file name. This is
incorrect for mingw32 hosts, generating false failures for those
tests.
I attempted to catch most of the occurrences of the pattern
".*/$srcfile" and replaced them with ".*$srcfile". The latter
is used elsewhere in the testsuite. The resulting patch is attached.
I also see other occurrences of the same assumption throughout the
testsuite, but usually they are arguments for function calls and i
seem to recall either the test harness or GDB deals with those
paths properly.

have empty bodies.
User-defined commands that have empty bodies weren't being shown because
the print function returned too soon. Now, it prints the command's name
before checking if it has any body at all. This also fixes the same
problem on "show user <myemptycommand>", which wasn't being printed due
to a similar reason.

I find some gdb.python tests fail on arm-none-eabi target, because the
tests assume that memory on address 0x is inaccessible. Some tests
(in gdb.base) are aware of this, so do a "x 0" check first. However,
the code is copy-n-paste.
This patch is to move the "x 0" check to a procedure in lib/gdb.exp,
and get needed tests call it. The original code matches pattern
"0x0:\[ \t\]*Error accessing memory address 0x0\r\n$gdb_prompt $", but
I remove it from the new proc is_address_zero_readable, because GDB
doesn't emit such message any more.
