MI -trace-find, print frame with LOC_AND_ADDRESS instead of SRC_AND_LOC.
When I looked for print_stack_frame calls in MI, I wondered why this
one passing down SRC_AND_LOC. print_stack_frame does:
/* For mi, alway print location and address. */
if (ui_out_is_mi_like_p (current_uiout))
print_what = LOC_AND_ADDRESS;
So it really doesn't matter which value is passed down, but, to avoid
confusion in readers, it's better to use the MI standard here.
There's another SRC_AND_LOC in mi-interp.c, but that one makes sense.

restore_selected_frame: tweak warning.
I noticed SRC_LINE has special handling within print_stack_frame (mid
statement handling), so I audited all uses, and noticed the one in
restore_selected_frame. I actually added this warning myself back in
2008, but reading back, I think we can do better. "reparsed frame" is
probably confusing to users.

bsd-kvm.c: Fix arguments to print_stack_frame.
1 is SRC_AND_LOC.
Then, this is passing -1 as print_level argument to print_stack_frame.
-1 is not a valid print_level value (it's a regular boolean). But, it
used to be, before
<https://sourceware.org/ml/gdb-patches/2004-04/msg00585.html>.
What happened is that bsd-kvm.c did not exist at the time of that

| * gdb_ptrace.h: Use ptrace64 instead of ptrace if HAVE_PTRACE64

... is responsible for this regression:
(gdb) x /x &__n_pthreads

Prior to the patch, we have:
(gdb) x /x &__n_pthreads
0xf06a8258 <__n_pthreads>: 0x00000003
The problem occurs inside rs6000_ptrace32, while calling ptrace64.
The address is given to rs6000_ptrace32 as an "int *", while
ptrace64 takes a "long long". The cast causes the address to be
sign-extended, which results in GDB trying to read the wrong address.
This patch fixes the issue by casting the address to a "uintptr_t"
instead, and letting the compiler do the implicit conversion to
"long long" in the function call.

fix gdb.arch to be parallel-safe
This fixes parts of gdb.arch to be parallel-safe.
I only changed the bits I could test on this machine.
I don't have access to many of the machines needed to fully switch
gdb.arch; but I am happy to provide advice to others attempting this.
Or, I can send an untested patch to convert it all.

introduce gdb_remote_download and finish parallel fixes in gdb.dwarf2
This finishes making gdb.dwarf2 parallel-safe.
To do this, this patch introduces a new gdb_remote_download proc, that
works somewhat differently in the one specific case where it matters:
for a copy to "host", if no destination was given, and the host is not
actually remote, then standard_output_file is used. In parallel mode
this guarantees that the resulting file will end up in a parallel-safe
location.
