178fbd72d3 Tidy up timerfd wrapper stuff a bit:
* make linux_kernel_2_6_22 return Bool

* linux_kernel_2_6_22: don't assert if /proc/sys/kernel/osrelease
  can't be opened

* PRE(sys_timerfd_create), PRE(sys_signalfd):
  use %ld for Word arguments, and use house types

4cae5c3ed5 Merge branches/OTRACK_BY_INSTRUMENTATION into the trunk. This adds
support to Memcheck for tracking the origin of uninitialised values,
if you use the --track-origins=yes flag.

This currently causes some Memcheck regression tests to fail, because
they now print an extra line of advisory text in their output.  This
will be fixed.

The core-tool interface is slightly changed.  The version number for
the interface needs to be incremented.

2e55cfac69 Make the clone system call wrappers call VG_(register_stack) to record
the new thread's stack, then make the stack unwinder use that information
to make a better guess at the stack bounds.

This helps avoid crashes trying to unwind the stack under wine when
the starting point is a routine without a proper stack frame.

29ff6066e9 Add a new flag, --child-silent-after-fork=no|yes [no]. When enabled,
causes child processes after fork to fall completely silent, which can
make the output a lot less confusing.  In addition it is pretty much
essential in XML output mode, so as to avoid mixing up any child XML
output with the parent's.

db29debc13 Make handling of setuid executables marginally more sensible, as
suggested in #119404.

Prior to this commit, if the current traced process attempted to
execve a setuid executable, an error was always returned.  The revised
behaviour is:

If the current (traced) process attempts to execve a setuid
executable:

* If --trace-children=yes is not in effect, the execve is allowed.

* If --trace-children=yes is in effect, the execve is disallowed
  (as at present), but an error message is printed (unless in XML mode),
  so at least the execve does not fail silently any more.

As per discussion on #119404 we could probably do a lot better, but
these changes are at least simple, useful and uncontroversial.

06666933d9 Merge (from branches/THRCHECK) the following two changes to the core-tool
interface:

r6805: Modify two thread-notification events in the core-tool
interface.  This removes track_post_thread_create and
track_post_thread_join.  The core can only see low level thread
creation and exiting, and has no idea about pthread-level concepts
like "pthread_create" and "pthread_join", so these are a bit
ambiguous.

Replace them with track_pre_thread_ll_create, which is notified before
a new thread makes any memory references, and
track_pre_thread_ll_exit, which is notified just before the new thread
exits, that is, after it has made its last memory reference.

r6823: Core-tool interface: give 'needs_tool_errors' an extra Boolean
indicating whether or not the core should print thread id's on error
messages.
