py-inferior.exp: Make sure local var is allocated on the stack.

The testcase, at some point, is trying to change the contents
of a string that was defined as follow:

    char *str = "hello, testsuite";

The problem is that the string is constant, and str is never used
to change the contents of the string in the program, so the compiler
is free to allocate it in a read-only section.  This is what happens
on x86-windows, for instance.

As a result, trying to change the contents of the string during
the `python gdb.inferiors()[0].write_memory (addr, str)' results
in the following error:

    (gdb) python gdb.inferiors()[0].write_memory (addr, str)
    gdb: write target memory, 5 bytes at 0x00403064

    gdb.MemoryError: Cannot access memory at address 0x403064
    Error while executing Python code.

This patch prevents this from happening by declaring str as an
array rather than a pointer.

gdb/testsuite/ChangeLog:

        * gdb.python/py-inferior.c (f2): Make str an array rather
        than a pointer.

ppc sim: Improve invalid option error message

This patch improves the error message when an invalid option is
detected, by also printing the option that actually caused the error.
For instance, from GDB:

        (gdb) target sim --hello
        Invalid option: --hello
        Usage:
        [...]

We also added the usage after an invalid long-name option (Eg: --hello)
to be in line with what's being done for all other invalid options
being detected.

sim/ppc/ChangeLog:

        * psim.c (psim_options): Add option that cause the error
        in invalid-option error messages. Print the usage when
        detecting an invalid long-name option.

ppc sim: Allow --sysroot command-line option

There was a recent change that cuased the "target sim" command
to add a --sysroot option to the argument vector passed down to
the simulator.  This caused a failure in the powerpc simulator,
as it did not recognize it.  This patch fixes the problem by adding
support for the --sysroot option (it ignores it).

sim: bfin: import testsuite

Now that the common sim testsuite code supports .S and .c files, we
can import the Blackfin testsuite.  There are about ~800 tests here,
so I'm only attaching a compressed patch of them.  Other than adding
files to sim/testsuite/sim/bfin/, the sim/configure.tgt file was
updated to mark Blackfin as having a testsuite, and sim/configure
regenerated.

sim: bfin: add support for glued SIC interrupt lines

The BF537 family glues a bunch of peripherals into single interrupt lines
that run into the SIC.  To model this same behavior in the sim, we need to
use the glue-or device, and in order to use that, we need to tweak things
a bit in the mach code to allow declaring of these new devices.

sim: bfin: push SIC mappings to device tree

The machs.c file is the best place for holding cpu-specific details, so
restructure the way the SIC manages its ports to do just that.  Now the
SIC's have a standard set of input pins and the different line routing
from peripherals is kept in the device tree only.  This better models
the hardware where the SIC doesn't care about the exact peripheral that
is sending it stuff, just which input pin it gets it on.
