Make internal_vproblem always work

internal_vproblem can be called (via malloc_failure) from almost the
first line of captured_main, but it will crash if called before the
first call to set_width.  This commit makes internal_vproblem work
at any time.

There are two parts to this.  If called before gdb_stderr is set up,
internal_vproblem will fall back to printing the message on regular
stderr and aborting.  If called after gdb_stderr is set up but before
filtered printing is set up, internal_vproblem will operate as usual
except that it can not query whether to quit and/or dump core so it
defaults to doing both.

gdb/ChangeLog:

	* utils.h (filtered_printing_initialized): New declaration.
	* utils.c (abort_with_message): New function.
	(internal_vproblem): Use abort_with_message for first level
	recursive internal problems, and if gdb_stderr is not set up.
	Protect calls to target_terminal_ours, begin_line and query.
