Use gdb_byte * instead of void *

This patch changes the argument type to gdb_byte * in order to align
with the to_xfer_partial interface.

gdb:

	* target.c (raw_memory_xfer_partial): Change argument type
	from void * to gdb_byte *.
	(memory_xfer_partial_1, memory_xfer_partial): Likewise.
fix crash in frame filters

apply_frame_filter calls ensure_python_env before computing the
gdbarch to use.  This means that python_gdbarch can be NULL while in
Python code, and if a frame filter depends on this somehow (easy to
do), gdb will crash.

The fix is to compute the gdbarch first.

Built and regtested on x86-64 Fedora 18.
New test case included.

fix erroneous error-handling in frame filter code

This fixes PR python/16487.

The bug here is that the function-name-handling code in py_print_frame
had a small logic error (really a misplaced closing brace).  This
error could lead to a Py_DECREF(NULL), which crashes.

This patch fixes the bug in the obvious way.

Built and regtested on x86-64 Fedora 18.  New test case included.

avoid python exception in FrameDecorator.py

This fixes a bug in FrameDecorator.py.

FrameVars seems to assume that Frame.block can return None if there is
no block.  However, it actually throws an exception.

I saw this bug while developing a frame filter, but unfortunately I
don't know how to reproduce it.  It seems to me that the SAL tests in
_is_limited_frame should exclude the bad cases; and in my attempts to
write a test they do.

Nevertheless I think the fix is reasonably obvious and ought to go in.

Issue a linker error if TLS sections are not adjacent

Bad linker script may lead to TLS sections separated by non-TLS sections
in output.  This patch changes linker assert to a linker error to
provide better linker diagnosis.

	if TLS sections are not adjacent.
Remove the display of known MCU names from the MSP430 port of GAS.

New MSP430 MCU parts are being created by TI all the time and the
list is basically always out of date.  Instead any name will be
accepted by the -mmcu= command line option.  ISA selection is now
based upon the -mcpu= command line option, just as is done for GCC.

gas/ChangeLog
	* config/tc-msp430.c (show_mcu_list): Delete.
	(md_parse_option): Accept any MCU name.  Accept several more
	variants for the -mcpu option.
	(md_show_usage): Do not call show_mcu_list.
