When trying to establish whether or not debuginfo should be read from
a file, first the mapping permissions _before_ peering at the file's
header, rather than afterwards. This changes the logic to behave more
like it does in 3.3.x. Fixes #164669, although really it is all still
rather fragile. The bug report,
http://bugs.kde.org/show_bug.cgi?id=164669, contains a detailed
explanation.

Add a second expected output. It appears that a recent glibcs print
one (or a value near it) as "+1.0000e+00" instead of "+1.0000e-00".
Or it could be a rounding issue .. I dunno.

Use a "sided" comparison rather than a "point" comparison, so as to

Sigh: /bin/sh on Ubuntu is not bash, it is dash (what a nuisance) and
it doesn't do the "[ ]" thing itself; instead it hands it off to
/usr/bin/[. And that doesn't understand "==" on strings; it wants "="
instead.

Add a new expected output for this test. Really it's a bad test,

Run this test -q, so as to remove the variance in outputs exhibited as
different numbers of blank lines than expected. I assume this
signifies that different numbers of forked-but-not-exec'd processes
are exiting, but I'm not sure.

Improvements to the suppression mechanism:
* Allow frame-level wildcarding in suppressions. Based on a patch by
Akos PASZTORY. Fixes #151612. With this change, a line "..." in a
suppression stacktrace matches any number of frames, including zero.
* Show line numbers in syntax errors when parsing supp files.

Merge Helgrind from branches/YARD into the trunk. Also includes some
minor changes to make stack unwinding on amd64-linux approximately
twice as fast as it was before.
Fix for bug 166581: use correct output file name after PID change
This is a little tricky because
* we want to check directly at startup whether the output file
can be written, thus the file name is set at beginning.
* a fork changes the PID in the child, and thus (potentially) the
output file name has to be updated. This best is directly before
generating the profile dump.
* the child after fork needs to be controllable via callgrind_control.
The setup of the control interface needs the new file name, too.
The fix is to allow multiple calls of CLG(init_dumps), everytime the
output file name is needed.

On ppc32/64 we don't have a reliable way to detect function entries
and exits at the moment. So disable stack array bounds checking for
ppc32/64 platforms. Also (unnecessarily) disables global array bounds
checking on those platforms.
Add a flag --enable-sg-checks=no|yes [yes] so that stack and global
checking can be optionally disabled on any platform. This is useful
because stack and global checking is much more expensive than heap
checking, and so it may be desirable to disable it.
