The original mtest routine only generated tests for noncontiguous
derived datatypes. This patch added two tests for every derived
datatype: (1) contiguous ddt (stride=block length) without lower-bound;
(2) contiguous ddt with lower-bound.

The original mtest routine used extent as the space required by
derived datatypes (i.e., to calculate the offset per datatype in a
data buffer). However, it is incorrect if the lower-bound is not zero.
The space must be lower-bound + extent. This patch fixed it.

Removes unnecessary thread yielding in threaded nonblocking context id
allocation algorithm. The error was introduced by "copy-pasting" from
the blocking context id allocation algorithm
(MPIR_Get_contextid_sparse_group) when implementing the nonblocking
algorithm. Note the subtle difference on thread handling between the
two. In the blocking algorithm, yield is needed to allow another thread
to make progress. In nonblocking algorithm, there is no need to yield to
another thread because this thread will not block the progress. On the
contrary, unnecessary yield will allow other threads to execute and
insert wrong order of entries to the nonblocking schedule and cause
errors.

If the destination of a LMT nonblocking send, which
follows a rendez-vous protocol, receives the RTS packet to the
unexpected queue followed by a cancelation request, the request in
the unexpected queue never gets freed. To solve the issue, we
forcefully free the rendez-vous request by adding an additional
request release operation. Refs #287

According to the standard, collectives using the same communicator must
implement thread safety in the application level. So, if using
MPI_Comm_spawn in THREAD_MULTIPLE safety level, it must use different
communicators.

I've modified the test to use different communicators per thread so that
we can still test its thread safety.

For tests that call pthread routines, add an explicit dependency.
This was not an issue previously, because either the compile wrappers
always added -lpthread, or the linker discovered the pthread symbols
via an interlibrary dependency on libmpi. However on FreeBSD 10, the
interlibrary dependency resolution appears more strict. Applications
must specify any libraries directly used, thus this fix.

If the user passes the -static flag, we disable interlibrary
dependencies, since the linker would pick the static versions of the
libraries in that case.

We are still making an assumption that the default mode of the linker
is shared, and the user can specify static library builds with
-static.  However, this is not always true.  On BG/Q, for example, the
default is static.

Fixes #2190.

This includes several changes:

1. Merged WRAPPER and EXTERNAL LIBS.  There is no reason to maintain
two names for these flags.  These are eventually appended and added to
the compiler wrappers anyway.

2. Updated mpicc and friend to add the necessary flags directly
instead of trying to merge these flags in configure.

It does not make sense for the user to specify LDFLAGS/LIBS that would
only be used to build the MPICH library, but not the user application.
Doing do will create a false dependency of the MPICH library on these
external libraries resulting in weird interactions with the user
application in cases where interlibrary dependencies are not
supported.  We were anyway silently modifying the WRAPPER LDFLAGS/LIBS
to include these anyway, so the flags themselves were weirdly screwed
up.

This patch simply removes them instead of pretending to allow them,
but not really allowing them.
