This:
...
$ cat ~/.gdbinit
define tui hookpost-enable
  focus cmd
end

define layout hookpost-src
  focus cmd
end

define layout hookpost-asm
  focus cmd
end

define layout hookpost-regs
  focus cmd
end

define layout hookpost-split
  focus cmd
end

define layout hookpost-next
  focus cmd
end

define layout hookpost-prev
  focus cmd
end
...
gets us a fair amount of the way, but has two caveats:
- doesn't work for gdb -tui.  When tui_enable is called, the hook is not
  installed yet.  We can't fix this by moving the hooks to .gdbearlyinit,
  because that's too early for define.
- doesn't work for new layouts, unless we add an additional hook for each
  of those.

Then again, the first caveat can be worked around by introducing some alias
that has the desired behaviour:
...
$ alias tui="gdb -q -tui -iex \"focus cmd\""
...
