279a7e01cf Update documentation on suppressions following addition of frame-level 
wildcarding in suppressions (r8725).  Also clarify a couple of bits of
wording.

53ed6e0dd5 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.

1b0a5e29a6 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.

25445f9819 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.

1eceb4282b Dwarf3 variable & type reader: use 64-bit numbers throughout to 
represent the sizes of types, even on 32-bit hosts, where a type with
a size >= 2^32 is, well, if not meaningless, then at least impossible
to instantiate.  This is of course motivated by reality .. on ppc32
SUSE11.0, the debuginfo for glibc-2.8 appears to contain a declaration
amounting to

  char __EH_FRAME_BEGIN__ [4294967296]
