swapping the roles of the VALGRIND_DO_CLIENT_REQUEST() and
VALGRIND_DO_CLIENT_REQUEST_EXPR() macros. Also, many __attribute__((unused))
declarations on variables have been eliminated. Closes#269778.
Note: so far this patch has been tested on x86/Linux, amd64/Linux and
ppc64/Linux but not yet on any other supported CPU/OS combination.

fd leak in vgdb.c
break missing in valgrind-low-s390x.c
* use option --vgdb=full for the tests mcsigpass.vgtest and mcsignopass.vgtest
This might improve these tests on ppc32/debian 6.0
* added a paragraph in gdbserver_tests/README_DEVELOPPERS to indicate
how to report problems about failing gdbserver tests.

on various platforms:
* In all gdbserver_tests using gdb:
Made a more general way to remove the initial start message.
* tests using threads burning cpu modified to have only 1 thread.
This makes them independent of the scheduler fairness.
* filter_gdb and filter_vgdb enhanced to anonymise
some debian 6.0/ppc specific things
some s390x/gdb 7.0, gdb 7.1 specific things
* vgdb.c: added an #include <linux/ptrace.h> to fix compilation
on s390x fedora and suse. (Christian Boerntrager)
* fixed a bug in valgrind-low.c debug log :
when a register size is 0, its image cannot be output (and register
should not be transferred).
* added a parameter --keep-unfiltered to vg_regtest.in
This will make it easier to update filter_gdb:
in case gdbserver_tests are failing due to "artificial"
differences to be filtered, re-run the tests using:
perl tests/vg_regtest --keep-unfiltered gdbserver_tests
Then a tar file with all the *.out in gdbserver_tests
will allow me to better/faster update the filter_gdb.
* made a better detection of a working PTRACE_GETREGS at compile time
and/or at run-time.
This is the patch on bug 214909 comment 69.

info created by LLVM 2.9 work properly. As per long discussion in
#272189, this isn't actually possible -- LLVM 2.9 creates bogus line
number info, and the bogusness can't be worked around at the Valgrind
end.

tid == VG_INVALID_THREADID rather than an uninitialised ThreadId.
Also in format_message, improve precondition assertions for
frameNo and tid.
There's no error in the current code since if frameNo == -1 then
tid is unused, but it caused IBM's BEAM checker to complain.

"insn_address >> 1". The former is appropriate for ARM code, where
all insns are 4-sized and 4-aligned, but not for Thumb code, where the
minimum size and alignment is 2. The old scheme happened to work for
Thumb (indeed, any hash function would), but caused huge amounts of
conflict misses in the fast cache for some programs.
The change has been observed to reduce conflict misses by up to 100
times, and in some cases, improves performance significantly for Thumb
code. Performance of ARM code is unchanged or possibly a bit worse.

on ppc32-linux. This is needed to make Altivec-using code work
correctly. Noticed when running ./auxprogs/gsl16test with gcc-4.6
with args -mcpu=970 -g -O3 -ftree-vectorize on Memcheck, in
which case a few of the tests failed because malloc() returns
8 byte aligned memory when it should return 16-aligned memory.
