7f196f23c4 When canonicalising CFI information, truncate overlapping address 
ranges and remove zero-length entries.  If these appear it's because
the generating compiler has created invalid CFI info.  Nevertheless we
should handle this robustly.  This fixes a bug reported by Bill
Hoover.

6789f6542e A commit which is almost all trivial change. 
- m_main: if --log-file-qualifier applies, do not add ".pid"
  at the end of the name

- Fix the logic which detected whether the just-devised name
  already existed.  This was broken (by me) because it could not
  distinguish the reasons for failing to open the logfile.

  Doing this required changing the return type of VG_(open)
  from Int to SysRes (to make failure reasons visible) and 
  that's the cause of most of the changes.

2e51dbbe3c Make VG_(kill_self) use kill to send the signal, not tkill, as we are 
sending it to the whole process not a single thread.

This routine is only used when we absolutely want to terminate
valgrind and as things stand it fails if called from anything other
than the initial thread as it winds up sending the signal to the main
thread only and that typically doesn't even exist any more so we
fall through and panic.

6be8d53922 This commit reduces the overhead of each heap allocation done by 
Valgrind's allocator, by overlapping the redzones (used when blocks
are in-use) with the prev/next ptrs (used when they are free).
This reduces the overhead for a heap block allocated by the core from
32B to 16B on 32 bit machines, and from 48B to 32B on 64 bit machines.

The only conceivable downside of this is that on 64 bit machines, if
the client frees a block and then writes past the start/end of it,
it will corrupt the metadata after only 8 bytes of overwriting, rather than
16 bytes.  Memcheck will have squealed to kingdom come by this time anyway.
(This won't happen on 32 bit machines because the overhead hasn't changed
for client blocks as allocated by Memcheck on 32 bit machines.)

I also tweaked the access functions.

61448c507d We have a nice little collection of text files describing various high 
level things.  But they're all over the place.  This commits moves
them all to the new docs/internals/ directory, and gives them
