[RFA] gdb_ari.sh patch to eliminate wrong critical errors

["Pierre Muller" <muller@ics.u-strasbg.fr>]

  strerror and floatformat_to_double are two
entries at top of ARI web pages
shown as critical regressions, but which are due to
changes in the implementations of their substitutes.
See
http://sourceware.org/gdb/current/ari/
  This patch fixes removes three entries:
1) strerror	2	Do not use strerror(), instead use safe_strerror()
2) floatformat to double	1	Do not use floatformat_to_double()
from libierty, instead use floatformat_to_doublest()
3) gdb/utils.c missing strerror
appearing in that order in the Critical section.

  I tested this locally and it does reduce the 
number of critical entries to 4.
  
  Daniel, could you please commit this?

  Remaining problems are:
1) inline	9	Do not use the inline attribute; 
since the compiler generally ignores this, better 
algorithm selection is needed to improved performance
  This problem is limited to three files:
vec.c (1) vec.h (7) and xtensa-tdep.c (1).
It could be easily removed, but I was wondering if 
there was a special reason why vec.h 
had some many.

2) GNU/Linux	4	Do not use `Linux', instead use `Linux kernel' 
or `GNU/Linux system'; comments should clearly differentiate between 
the two (this test assumes that word `Linux' appears on the same line 
as the word `GNU' or `kernel'
  This one is a little too subtle for me, as I am hardly able to
distinguish between 'GNU/Linux system' and 'Linux kernel'...

3) hash	3	Do not use ` #...', instead use `#...'
(some compilers only correctly parse a C preprocessor directive 
when `#' is the first character on the line)
  This 3 appearances are in:
  ada-lex.c (2) and xtensa-tdep.c (1)
  But ada-lex.c is an automatically generated file, and I am even wondering
why 
this file is checked.

4) obsolete system	2	No config file for system
These 2 entries are configure.host and configure.tgt
which are again generated files...

ChangeLog pseudo-entry:

2007-10-10  Pierre Muller  <muller@ics.u-strasbg.fr>

	* gdb_ari.sh (strerror): update rule to reflect
	implementation of safe_strerror in posix-hdep.c and mingw-hdep.c.
	(floatformat_to_double): update rule to accept
	call in gdb/doublest.c source.
