7b1a5978c9 drd: Handle pthread_cond_destroy() failure properly

40644676b1 Introduce DISABLE_PTHREAD_SPINLOCK_INTERCEPT flag 
The flag DISABLE_PTHREAD_SPINLOCK_INTERCEPT is set only for MIPS32, and it is
used in DRD and Helgrind as a workaround for the issue #311690.
In short, pthread_spin_lock implementation has local branches to the start of
the function which interferes with the redirection system in Valgrind that
assumes it has to redirect each call/branch to a particular address.

e76f96cd60 drd: Fix a race condition in the pthread_create() intercept. 
Avoid that the futex wake call in DRD_(sema_up)() can get invoked after the semaphore has
already been destroyed. This is most likely the real fix for the bug described in the
commit message of r12332.

084b7cb10b Fix #284384 (clang 3.1 -Wunused-value warnings in valgrind.h, 
memcheck.h) by changing a bunch of VALGRIND_DO_CLIENT_REQUEST_EXPR
into VALGRIND_DO_CLIENT_REQUEST_STMT for cases where the return value
of the former would be unused.  (Bart Van Assche, bart.vanassche@gmail.com)

Note: I haven't analyzed yet since which commit these false positives
started to appear but it's most likely a commit applied after the 3.6

eea9337891 The pthread.h on Android has no definition for pthread_rwlock_t, which 
makes the associated intercepts in Helgrind and DRD un-compilable.
Add a configure test for it, and use them to guard the aforementioned
intercepts.

9a36fe677e Get rid of the remaining "set but not used" warnings reported by gcc 4.6 by 
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.

22baa8bb07 Implemented a more systematic approach for intercepting POSIX threads 
functions: for each function name to intercept, intercept the function
name itself, the function name with @* appended (versioned symbols on
Linux) and the function name with $* appended (versioned symbols on
Darwin). Updated filter_stderr such that symbol versions are removed.
Updated the expected output files that contain names of intercepted
functions.

6529f12189 Replaced code for suppressing the stack memory in use at the time a 
thread is being created by code for suppressing the memory allocated
from inside the pthread_create() call. The new implementation should be
a more portable solution for suppressing data races triggered by the
thread-local-storage implementation of a Pthreads library.

07045477ca Merge the DARWIN branch onto the trunk. 
I tried using 'svn merge' to do the merge but it did a terrible job and
there were bazillions of conflicts.  So instead I just took the diff between
the branch and trunk  at r10155, applied the diff to the trunk, 'svn add'ed
the added files (no files needed to be 'svn remove'd) and committed.
