Apparently with glibc >= 2.18 the value returned by pthread_mutexattr_gettype()
is not the same as the value passed to pthread_mutexattr_settype(). Add a
workaround for this glibc bug.

When all threads are blocked in a syscall, DRD_(thread_get_running_tid)()
returns (or can return?) a "valid" DrdThreadId (probably the last one
that was running ?).
However, in such a situation, VG_(get_running_tid)() returns 0 (as effectively
there is no thread running).
This discrepancy (drd_tid "valid" and "vg_tid" invalid) can (probably) only
happen with gdb monitor commands, as a thread can (normally) execute a
client request only when it is running.
However, vgdb can "force" the invocation of the gdb monitor client request,
even if no thread is running.
In such a case, the assert should not verify that drd_tid and vg_tid are
consistent.
To reproduce the problem:
./vg-in-place --tool=drd sleep 60
and in another window:
./coregrind/vgdb help
which then gives
...

Move memcheck/mc_replace_strmem.c to shared/vg_replace_strmem.c and
add several intercepts for SSE-variants. Include that source file from
drd/drd_strmem_intercepts.c, helgrind/hg_intercepts.c and
memcheck/mc_replace_strmem.c.
Merge memcheck/tests/filter_memcpy into tests/filter_stderr_basic.
Update tests/check_headers_and_includes.

Option -v outputs a list of used suppressions. This only gives
the nr of times a suppression was used.
For a leak search, this only gives the nr of loss records that
have been suppressed, but it does not give additional needed details
to understand more precisely what has been suppressed
(i.e. nr of blocks and nr of bytes).
=> Add in the tool interface update_extra_suppression_use and
print_extra_suppression_info functions to allow the tool to record
additioonal use statistics for a suppression. These statistics
can be done depending on the error (and its data) which is suppressed.
Use this in memcheck for the leak suppressions, to maintain and output
the nr of blocks and bytes suppressed by a suppression during
the last leak search.

clang 3.3 produces an error message for /usr/include/c++/4.6/chrono
which happens to get included somewhere inside <thread>.
This happens with C++ headers from:
gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3.

Non-POD variable length arrays are supported by g++ but not by clang.
Hence convert the variable length array in this test program into a vector.

(1) Detect availability of pthread_setname_np. Ignore testcases
memcheck/tests/threadname[_xml] if not available.
(2) Enable _GNU_SOURCE to avold compiler warnings.
(3) In threadname_xml filter out stackframes referring to system
libraries. Added tests/filter_xml_frames to do that.
(4) Adjust .exp files as needed
(5) Do not ship stdout.exp for memcheck/tests/threadname[_xml].

If a suppression file contains an error, the lineno reported could be wrong.
Also, give filename and lineno of the used suppressions in -v debugging output.
The fix consists in ensuring that tool specific read_extra function gets
the Int* lineno pointer, together with other VG_(get_line) parameters.

exp-32bit files needed minor update for the last store, and some mips32
platforms also need additional exp-mips32 due to different way of loading
and storing double values.
This fixes drd/tests/annotate_trace_memory on different 32-bit platforms.

Workaround for bug #318643. Disable the tests for now so they don't
go into an infinite loop and fill up the disks on arm, ppc32 or ppc64.
