Fix up all failures encountered when running the testsuite with
GDB_DEBUG="infrun".
Some tests rely on enabling debugging for various components. With
debugging on, this will be lost to the debug file.
Disable separate tty for mi tests when debugging. This currently
does not work.
disasm.c should send errors to the stderr instead of the logfile.
Note that enabling debug for other components might still cause
additional errors above what has been fixed here.

* disasm.c (set_disassembler_options): Send errors to stderr.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

I was looking for a way to reproduce easily PR 22979 by doing this:
(gdb) set architecture i386:x86-64
(gdb) set osabi none
However, I noticed that even though I did "set osabi none", the gdbarch
gdb created was for Linux:
(gdb) set debug arch 1
(gdb) set architecture i386:x86-64
...
(gdb) set osabi none
gdbarch_find_by_info: info.bfd_arch_info i386:x86-64
gdbarch_find_by_info: info.byte_order 1 (little)
gdbarch_find_by_info: info.osabi 4 (GNU/Linux) <--- Wrong?
gdbarch_find_by_info: info.abfd 0x0
gdbarch_find_by_info: info.tdep_info 0x0
gdbarch_find_by_info: Previous architecture 0x1e6fd30 (i386:x86-64)
selected
gdbarch_update_p: Architecture 0x1e6fd30 (i386:x86-64) unchanged
This is because the value GDB_OSABI_UNKNOWN has an unclear role,
sometimes meaning "no osabi" and sometimes "please selected
automatically". Doing "set osabi none" sets the requested osabi to
GDB_OSABI_UNKNOWN, in which case gdbarch_info_fill overrides it with a
value from the target description, or the built-in default osabi. This
means that it's impossible to force GDB not to use an osabi with "set
osabi". Since my GDB's built-in default osabi is Linux, it always falls
back to GDB_OSABI_LINUX.
To fix it, I introduced GDB_OSABI_NONE, which really means "I don't want
any osabi". GDB_OSABI_UNKNOWN can then be used only for "not set yet,
please auto-detect". GDB_OSABI_UNINITIALIZED now seems unnecessary
since it overlaps with GDB_OSABI_UNKNOWN, so I think it can be removed
and gdbarch_info::osabi can be initialized to GDB_OSABI_UNKNOWN.
gdb/ChangeLog:
PR gdb/22980
* defs.h (enum gdb_osabi): Remove GDB_OSABI_UNINITIALIZED, add
GDB_OSABI_NONE.
* arch-utils.c (gdbarch_info_init): Don't set info->osabi.
* osabi.c (gdb_osabi_names): Add "unknown" entry.
gdb/testsuite/ChangeLog:
PR gdb/22980
* gdb.base/osabi.exp: New file.
