Skip symbols from IRQ stack.
...
There is a bug in the kernel where it includes the stack of the IRQ
that generated the event, so that the stack ends up looking like this:
[ip] [irq stack] [real stack].
As a temporary workaround, this patch filters out the irq stack
symbols.

Show the "-- kernel --" marker in kernel threads
...
The innermost context is normally user mode, so we don't show. For
kernel threads, the innermost context is the kernel, so don't filter
it out.

Disable accessibility
...
Accessibility prevents sysprof from working reliably, so disable
it. Specifically, it
- causes large amounts of time to be spent in sysprof itself
whenever the label is updated.
- sometimes hangs at shutdown
- does long-running roundtrip requests that prevents
reading the event buffers, resulting in lost events.

Beginning of the end for BinParser.

Instead of the clunky BinParser, we are moving to a scheme where the
ELF accessors are defined by macros. This is the first step towards
getting rid of it.
