For current process, check memory accesses.
When attempting to unwind the current process, the library simple reads and
writes to memory for memory accesses. Unfortunately, if an unwind winds up
with invalid data, then the process can segfault. Add a guard to all memory
accesses that verifies that reads/writes are valid before attempting them.
For now, this guard is a nop on all systems except linux systems.
Also, modify the adjust_ip function to use the access_mem function
so that all reads go through the right function.

ARM: invalidate proc info after non-dwarf unw_step()
After successfully stepping the cursor on ARM, the proc info is
invalidated only in dwarf_step(). Invalidate the proc info also when
stepping with the non-dwarf based methods. This fixes
unw_get_proc_info() returning stale data.
The core dump unwinder can be used for demonstrating the bug. When
unwinding based only on DWARF data, the proc info is correct:
$ UNW_ARM_UNWIND_METHOD=1 ./test-coredump-unwind core `cat backing_files` 2>/dev/null
ip=0x000086d8 proc=000086d4-000086dc handler=0x00000000 lsda=0x00000000
ip=0x000086ef proc=000086dc-000086f2 handler=0x00000000 lsda=0x00000000
ip=0x000086e7 proc=000086dc-000086f2 handler=0x00000000 lsda=0x00000000
ip=0x00008597 proc=00008584-0000859a handler=0x00000000 lsda=0x00000000
ip=0x76e3ac3b proc=76e3aba0-76e3acec handler=0x00000000 lsda=0x00000000
When unwinding based only on the exidx method, we see the proc info
lagging behind:
$ UNW_ARM_UNWIND_METHOD=4 ./test-coredump-unwind core `cat backing_files` 2>/dev/null
ip=0x000086d8 proc=000086d4-000086db handler=0x00000000 lsda=0x00000000
ip=0x000086ef proc=000086d4-000086db handler=0x00000000 lsda=0x00000000
ip=0x000086e7 proc=000086dc-000086f3 handler=0x00000000 lsda=0x00000000
ip=0x00008597 proc=000086dc-000086f3 handler=0x00000000 lsda=0x00000000
ip=0x76e3ac3b proc=00008584-0000859b handler=0x00000000 lsda=0x00000000
ip=0x000085c3 proc=76e3aba0-76e3ae4b handler=0x00000000 lsda=0x00000000
Finally, with this patch applied, we get the desired proc info also with
the exidx unwinder:
$ UNW_ARM_UNWIND_METHOD=4 ./test-coredump-unwind core `cat backing_files` 2>/dev/null
ip=0x000086d8 proc=000086d4-000086db handler=0x00000000 lsda=0x00000000
ip=0x000086ef proc=000086dc-000086f3 handler=0x00000000 lsda=0x00000000
ip=0x000086e7 proc=000086dc-000086f3 handler=0x00000000 lsda=0x00000000
ip=0x00008597 proc=00008584-0000859b handler=0x00000000 lsda=0x00000000
ip=0x76e3ac3b proc=76e3aba0-76e3ae4b handler=0x00000000 lsda=0x00000000

Call dwarf_step only if CONFIG_DEBUG_FRAME is defined
The ARM EABI does not use the .eh_frame and .eh_frame_hdr sections for unwinding. Therefore it doesn't make sense to call dwarf_step if CONFIG_DEBUG_FRAME is not defined.

This patch add support for resuming at a certain stack frame even if signal

is used. RT and non-RT signal frames are handled for both >=2.6.18 and

Have the ARM extbtl-parser operate on the DWARF model directly.
This eliminates the arm_stackframe and therefore the need to synchronize the
two models. It also clears the way for unwinding call stacks with mixed
DWARF- and extbl-frames.
