[RFA][python] Add gdb.Value.string method.

Hi,

This patch adds a method to the Value python class which returns the
value as a Python Unicode string. It depends on the patch I just posted
in the "Add la_getstr member to language_defn", and assumes that the
"Fixes and improvements to gdb.Value" patch has been applied. Ok?

[commit] Start of New Year Procedure applied...

Hello,

Just a quick note to let everyone know that I applied the Start of New
Year procedure as documented in our internals manual:
  - 2009 added to the copyright notices
  - GDB now prints 2009 as its copyright year
  - ChangeLog has been rotated (with associated fnchange.lst update)

The update of the copyright notices was performed by a script
using emacs. I reviewed about 20% of the changes before giving up,
and everything seemed to be fine. Let us know if you see something
wrong or some files that we missed.

2009-01-03  Joel Brobecker  <brobecker <at> adacore.com>

        Updated copyright notices for most files.

2009-01-03  Joel Brobecker  <brobecker <at> adacore.com>

        * top.c (print_gdb_version): Update copyright year.

2009-01-03  Joel Brobecker  <brobecker <at> adacore.com>

        * config/djgpp/fnchange.lst: Add entry for ChangeLog-2008.

This part is approved, but I have a few comments:

> + <at> findex gdb.history

The text below this does not mention "gdb.history" at all.  Should it?
I could imagine a reader who gets here by following the "gdb.history"
index entry, and is then puzzled by not finding that text anywhere.

> +If  <at> var{number} is less than or equal to zero, then  <at> value{GDBN} will

> +last element to find the value to return.

For clarity, I'd separate the zero case and the negative case.  First,
"is less than or equal to zero" is a mouthful that would be eliminated
then; you could simply say "negative".  And second, "count zero
elements backward" is an abstraction that is a better avoided.

Committed: fix size of CRIS special register 2

Had I used the name (PID), I would have trigged that this'd to
be the wrong size.  For reference,

Committed.

	of number 2, PID.

	* cris/semcrisv32f-switch.c: Regenerate.

Simics has it to, in some different ways:

skip-to <bookmark> 
reverse n time units
continue n time units

I think this is a good example of the kind of new commands and abilities that
come with having a reverse ability in the first place, like Marc said. 

And as the later discussion evolved, it would be jolly nice to have an idea of
time in gdb. I think that is needed anyway to handle multicore, multiprocessor,
and multithreaded debug: when things happen in disparate locations under the
control of a single debugger quickly gets very interesting...

Best regards,

Committed: add access syscall to sim/cris

The access syscall was used one way or another (perhaps it was
just in an error path) in hello-world with glibc-2.9 (eglibc).

I see it's also used in the gfortran testsuite, so this will
hopefully change a few FAILs with "Unimplemented syscall: 33
(0x3dfff...)" in the log to PASS for cris{,v32}-axis-linux-gnu
later on.

sim/testsuite:
	* sim/cris/c/access1.c: New test.
sim:
	* cris/traps.c (TARGET_SYS_access, TARGET_R_OK, TARGET_W_OK)
	(TARGET_X_OK, TARGET_F_OK): Define.
	(cris_break_13_handler) <case TARGET_SYS_access>: New case.
