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.

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.

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.

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.

AIX only: print name of missing syscall as well as number -- important
because there is no fixed name/number binding.

- track SysRes changes
- track VG_(am_find_nsegment) const-ness change
- increase number of client syscall args supported from 6 to 8
- simplify type SyscallStatus. Simply hold a copy of the SysRes
for the syscall rather than have this be a data structure
incorporating something very similar to the fields of a SysRes,
and more besides. Change various macros in priv_types_n_macros.h
to match.

functions for AIX.

too difficult.
