Don't mention "Unix" in native target name.

I find the mention of "Unix" unnecessary (and really slightly a lie)
on GNU/Linux in a couple of places:

 (gdb) maint print target-stack
 The current target stack is:
  - multi-thread (multi-threaded child process.)
  - child (Unix child process)
  - exec (Local exec file)
  - None (None)

 (gdb) help target child
 Unix child process (started by the "run" command).

 (gdb) target child
 Use the "run" command to start a Unix child process.

It's also odd that e.g., the Windows port says "Unix" in reaction to
"target child" (it was already that way before Windows used
inf-child.c):

 (gdb) target child
 Use the "run" command to start a Unix child process.
 (gdb)

So drop "Unix", going in the direction of saying mostly the same on
all native targets:

  (gdb) maint print target-stack
  The current target stack is:
   - multi-thread (multi-threaded child process.)
 - - child (Unix child process)
 + - child (Child process)
   - exec (Local exec file)
   - None (None)

  (gdb) help target child
 - Unix child process (started by the "run" command).
 + Child process (started by the "run" command).

 (gdb) target child
 -Use the "run" command to start a Unix child process.
 +Use the "run" command to start a child process.

Rename Solaris's target to "target child" like most other ports.

Note that "target procfs" is used by QNX, but the test must be failing
there, as nto-procfs.c overrides to_open with a method that doesn't
throw the error being tested.  So I'm just removing the test
completely.

daily update
Rename native-only terminal related functions.

Looking at target_terminal_inferior etc. in async mode, I realized
that the naming of the terminal_inferior, terminal_ours,
etc. functions doesn't really give a clue that they're meant for the
native target only.  This patch renames them.  There's already
child_terminal_info using the child_ prefix, and, they're most
prominently installed by inf-child.c, so I went with the child_
prefix.  I dropped "inferior" from a couple to make the name match the
corresponding target method.

Tested on x86_64 Fedora 17, and cross built for mingw.  I didn't test
gnu-nat.c, but I think the change is as obvious as it gets.  I grepped
the tree looking for other potential spots that would need adjustment
but this is all I found.  If something breaks, it should be trivial to
fix.
