This commit makes it possible to set relative priorities for
components. Before the addition of the patched component there was
only one component that would run on any system but that is no longer
the case. When determining which component to open each component's
query function is called and the one that returns the highest priority
is opened. The default priority of the patcher component is set
slightly higher than the old ptmalloc2/ummunotify component.
This commit fixes a long-standing break in the abstration of the
memory components. ompi_mpi_init.c was referencing the linux malloc
hook initilize function to ensure the hooks are initialized for
libmpi.so. The abstraction break has been fixed by adding a memory
base function that calls the open memory component's malloc hook init
function if it has one. The code is not yet complete but is intended
to support ptmalloc in 2.0.0. In that case the base function will
always call the ptmalloc hook init if exists.

* datatype: Fix a incorrect datatype name of `MPI_UNSIGNED`
Name of predefined datatype for C `unsigned int` gotten by
`MPI_TYPE_GET_NAME` should be `MPI_UNSIGNED`, not `MPI_UNSIGNED_INT`.
* datatype: Fix incorrect datatype names of `MPI_C_BOOL` and `MPI_CXX_*`
Names of predefined datatypes gotten by `MPI_TYPE_GET_NAME` are:
after this commit (correct) | before this commit (incorrect)
-----------------------------------------------------------
MPI_C_BOOL MPI_BOOL
MPI_CXX_BOOL MPI_BOOL
MPI_CXX_FLOAT_COMPLEX MPI_C_FLOAT_COMPLEX
MPI_CXX_DOUBLE_COMPLEX MPI_C_DOUBLE_COMPLEX
MPI_CXX_LONG_DOUBLE_COMPLEX MPI_C_LONG_DOUBLE_COMPLEX
* datatype: Fix a incorrect datatype name of `MPI_2DOUBLE_PRECISION`
Name of the predefined datatype for Fortran two `double precision`
gotten by `MPI_TYPE_GET_NAME` should be `MPI_2DOUBLE_PRECISION`,
not `MPI_2DBLPREC`.
This bug was caused by setting the name to `opal_datatype_t::name`
instead of `ompi_datatype_t::name`.
* datatype: Fix `MPI_UNSIGNED_CHAR` internal flag
`MPI_UNSIGNED_CHAR` is an integer type.
* ompi/cxx: Fix C++ `MPI::LONG_DOUBLE_INT` definition
Just a typo fix. Without this fix, `MPI::MAX_LOC` and `MPI::MIN_LOC`
cannot be used with `MPI::LONG_DOUBLE_INT` in C++ programs.
I know the C++ binding is obsolete, but fixing this is harmless.

This commit adds the following symbols
MPI_Alloc_mem_cptr_f
MPI_Alloc_mem_cptr_f08
PMPI_Alloc_mem_cptr_f
PMPI_Alloc_mem_cptr_f08
These are implemented in the same way as other `_cptr` routines.
Before this commit, a same PML tag may be used for distinct
communications for long messages. For example, consider a condition
where rank A calls ```MPI_PUT``` targeting rank B and rank B calls
```MPI_GET``` targeting rank A simultaneously.
A PML tag for the ```MPI_PUT``` is acquired on rank A and is used
for the long-message communication from rank A to rank B.
A PML tag for the ```MPI_GET``` is acquired on rank B and is used
for the long-message communication from rank A to rank B.
These two tags may become a same value because they are managed
independently on each rank. This will cause a data corruption.
This commit separates the tag used in a single RMA communication
call, one for communication from an origin to a target, and one
for communication from a target to an origin. A "base" tag
is acquired using ```get_tag``` function and PML tag is caluculated
from the base tag by ```tag_to_target``` and ```tag_to_origin```
function.
`sendcounts`, `sdispls`, and `sendtype(s)` must be ignored
if `MPI_IN_PLACE` is specified for `sendbuf`.
This commit makes the param check code same as the blocking
`ALLTOALL{V|W}` function.
This commit ensures the bml is always enabled whether or not it will
be used. This ensures that any available btls communicate their modex
so that they can be used for one-sided communication.

Or at least that was the origin of the issue. It turns out
we were freeing the wrong buffer (but as it only happen in the
case of an error we never noticed).
This patch addresses most (if not all) @derbeyn concerns
expressed on #1015. I added checks for the requests allocation
in all functions, ompi_coll_base_free_reqs is called with the
right number of requests, I removed the unnecessary basic_module_comm_t
and use the base_module_comm_t instead, I remove all uses of the
COLL_BASE_BCAST_USE_BLOCKING define, and other minor fixes.
