On Solaris, we still do get error reports about destroying
a barrier which was never initialized even after SVN r15962.
We also get an error report about destroying barrier bar3
which is still waited upon by a thread.

This is a workaround for bug #358213 helgrind/drd pthread_barrier tests
hangs with new glibc pthread barrier implementation. This makes sure that
the tests don't hang anymore. It does this by creating new threads that
sleep and kill the other threads after some time. But this introduces
some non-determinism that might cause the tests to occassionally fail
(both against old and new glibc implementations).

Both tests define a execute_native_thread_routine function that we
took from libstdc++. Unfortunately because of a bug this function
is not local in some versions of libstdc++ and so our similar named
function will clash when trying to link.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70476#c2
Simply rename our version to work around this.
Since we don't build this part of the test code for gcc >= 6, this
issue only happens if the buggy libstdc++ thread code is used together
with gcc 5. This is the case with for example devtoolset-4-gcc-5.

At many places, we have:
VG_(fun(a,b,c))
instead of
VG_(fun)(a,b,c)
So, fix these cases, found using:
grep -n -i -e 'VG_([a-z][a-z0-9_]*[^a-z0-9_)]' *.c */*.c */*/*.c

Ivo Raisr had reported that thread startup was slow on Solaris.
This patch reduces the thread startup time on Solaris.

In case we do recognize the xend, but detect it is invalid
(used outside a transaction) we generate a segsegv instead
of a sigill. Handle that in the same way in the test case.

when a pthread_rwlock is used in an invalid way.
Recent glibcs use transactional memory instructions to do lock ellision
but will sometimes, when locks are used in an invalid way, may calls to
xend on systems which don't support it, on the grounds that the program
is invalid anyway.
So we try and catch and ignore the resulting SIGILL in our tests that
deliberately work with invalid locks.

Two things:
- remove the buffer argument from VG_(DebugInfo_sect_kind)
- allocate AddrInfo::SectKind::objname dynamically

This is (a) consistent with how the other containers are defined
and, more importantly, (b) allows the constification of the hash table API.

The change eliminates the fixed size buffers in gen_suppression and
show_used_suppressions. This is achieved by changing the return type from
VG_TDICT_CALL(tool_get_extra_suppression_info and
VG_TDICT_CALL(tool_print_extra_suppression_use from Bool to SizeT.
A return value of 0 indicates that nothing (except the terminating '\0'
which is always inserted) was written to the buffer. This corresponds to the
previous False return value. A return value which is equal to the buffer
size (that was passed in as function argument) indicates that the buffer was
not large enough. The caller then resizes the buffer and retries.
Otherwise, the buffer was large enough.
Regtested with a resize value of 1.

- Document that the allocation function must ot return NULL.
- As a conequence of the previous requirement the various Create and AllocNode
functions cannot return NULL. Remove pointless asserts at call sites.
- Remove documentation of undefined function CreateWithCmp.
- Names of library functions (such as 'free') are reserved as a are names
beginning with underscores. Don't use those.

There are plans to enable --read-inline-info=yes for all Valgrind
tools. Hence make the DRD regression test output independent of how
--read-inline-info has been set.

as opposed to the valgrind code proper. In particular, make sure that
-mpreferred-stack-boundary=2 does not get used for the preload shared
objects, since that can cause the stack to become misaligned and leads
to segfaults. Modified version of a patch from Matthias Schwarzott
(zzam@gentoo.org). Fixes#324050.
Also, fix the configure check in configure.ac for
-mpreferred-stack-boundary=2 so that it checks whether this is
allowable for 32-bit code generation even on 64-bit (x86) hosts. This
check was wrong before now and led to 32-bit builds on 64-bit hosts
generating poorer code for speed critical helper functions (eg
helperc_LOADV32le) than on 32-bit builds on 32-bit hosts.
