When the conditions are right, we use libtool's interlibrary
dependencies to only link the application with the minimum set of
libraries required.  Those libraries will pull in the other required
libraries on demand.  That way, the application library dependencies
would be minimal, allowing us to add/remove extra libraries in the
future.

The "conditions are not right" when one of the following is true:

1. MPICH shared library builds are disabled.

2. libtool doesn't support interlibrary dependencies on this platform.

3. The user passed -static or -mpich-alllibs to the command line.

4. Interlibrary dependency tracking is explicitly disabled at
configure time.

The following library names are used to make the naming consistent
across the ABI compatibility group:

C libraries: libmpi.* and libpmpi.*
C++ library: libmpicxx.*
F77 libraries: libmpif77.*
F90+ library: libmpifort.*

This patch also gets rid of the FWRAPNAME variable, which is a
duplicate of MPIFLIBNAME.  Similarly, FCWRAPNAME is removed and a new
variable MPIFCLIBNAME is added, so it's consistent with the other
names.

PMPIFLIBNAME, which was unused, is no longer present.

Fixes #2039.

f77 and f90 were not consistent names with respect to what the code
was providing.  For example, "f90" also used code from "f77".  This
patch changes the naming to "mpif_h" and "use_mpi", which correspond
to using the mpif.h and "use mpi module" conventions specified by the
MPI standard.

This also includes changes to buildiface, autogen.sh and .gitignore to
work with these changes.

1. enable-fast=all|none should really reflect "all"/"none", not
"some".  We were enable some of the optimizations, but not all, e.g.,
mpit pvars disabling.

2. Making naming consistent and move related checks closer to each
other, so they are easier to verify.

3. Don't control enable-timing, enable-mpit-pvars, and
enable-error-checking from enable-fast.  They have their own configure
options.  enable-fast is kind of weird in that it sets some of its own
configure variables, but also resets variables set by other configure
options making it very confusing for users.  Instead we should point
out in the README what users should do for performance tests.

4. Allow optimization levels like O3 to be used with other enable-fast
options, such as ndebug.

5. Remove some incorrect and/or unnecessary comments.

6. Don't force default compiler optimizations with --disable-fast is
given.

   are necessary.

Simplify logic in compile wrapper scripts. Use configure substitutions
where possible to better match pkg-config style.

Signed-off-by: Pavan Balaji <balaji@mcs.anl.gov>

Includes the following modifications by Pavan Balaji:

Remove the PAC_COMPILER_SHLIB_FLAGS usage, instead of modifying the
macro in confdb.

The ordering of flags in mpicc and friends does not match that of
pkg-config.  This is because of two reasons.

1. pkg-config reorders flags when it outputs them.  This requires us
to manually adjust the flags in mpicc to match up, and is error prone.

2. mpicc and friends provide LDFLAGS before the user-specified flags,
followed by the include and library directories.  This is to make sure
that the LDFLAGS are listed before the application source file.
Reordering them to match pkg-config loses this flexibility.

In C, left-shift has well-defined behavior, but right-shift does not

bits with 0's or 1's.  In this patch, we type-cast the values to
unsigned integers to make the behavior well-defined.

In some cases, MPIR_COUNT_ALIGNMENT was not being defined.  This
fixes that case, which came up when trying the -feature=fint=on option
for the Fortran 77 code.

This was changed to 1024 to give space for larger error strings.  But
this caused an ABI breakage for a number of MPICH partners.  This
patch reverts the size back the size to what we had in older mpich
releases.

The previous patch was meant to allow devices to automatically pick
