Status of my valgrind branch

Hi,

the valgrind branch is not ready yet.  And it grew to 8 patches in the 
meantime:

http://repo.or.cz/w/git/dscho.git?a=log;h=c9486d38d070fefe39f90512e2e12d3a64eba1b3

There is one big problem I only realized today, when trying to catch that 
valgrind bug [*1*]: in the suppression file, I introduced the "..." 
notation, which is only available with valgrind 3.4.0.  Which was 
published this month.

So I have to think about the issue a bit more, and maybe just claim that 
valgrind 3.4.0 is required.  But maybe there are people who disagree with 
me saying that older valgrind should be supported.

Ciao,
Dscho

[*1*] Turns out that the issue I was reporting happens with Ubuntu's zlib, 
which I erroneously thought would be pretty vanilla.  It is not: it was 
compiled with "-O3 -DUNALIGNED_OK", both of which are required to hit the 
bug.

Still, it is a bug in valgrind, I am pretty sure by now, as the byte is 
not uninitialized as valgrind claims.

Oh, and I wasted a _lot_ of time on this today.
