hwloc configure: fix typo -- add missing $

Arrgh!  Missed a "$" in the last commit, making the test always
false.
plm base: move flag inside the #if in which it is used

Avoid a compiler warning by declaring the tflag only inside the #if in
which it is used (i.e., if hwloc support is built).
libfabric: don't LIBADD the common library in the static case

Adding the libfabric common library in the --disable-dlopen case will
result in duplicate symbols.
OPAL: skip comparison when when fs=autofs in mtab, because we are looking for reals fs type
Merge pull request #319 from miked-mellanox/topic/opal_path_nfs_autofs

skip check for autofs if fstype is autofs jenkins: check
Bump up max send size.  Gives much better performance for GPU transfers while only decreasing host transfers by a small amount.
This was not supposed to be part of the 1895f29 commit.
If we are using hwthread cpus, then default to binding there, letting the user override to whatever they want
If someone specifies the bitmap for hwthreads and wants hwthread cpus, then don't parse the slot list as it expects cores - just copy the provided bitmap across as it already has the required info
man: update a bunch of attribute-related man pages

Per discussion starting
http://www.open-mpi.org/community/lists/users/2014/12/26018.php, at
least note that OMPI does not allow adding or deleting attributes in
an attribute copy or delete callback (or any of its children) on the
same object on which the callback was invoked.
LSF expresses its affinity file in hwthreads and expects those to be used as cpus, so set things accordingly

libfabric: add missing header file
gitignore: trim a lot of kruft

This gitignore was simply the catenation of all the svn:ignore
properties.  However, .gitignore is pretty good at regular expressions
that span the entire tree, so we can consolidate/remove a lot of
redundant entries.
Revert "libfabric: add missing header file"

That wasn't a missing header file; in fact, it should have been
.gitignored!

This reverts commit 35bf5fc60c4970f988e80c7101fd5f27a22ea790.
gitignore: even more regexp ignores

Simple regexps to always ignore the hwloc/libevent stuff, regardless
of their specific version.

Yay regexps!
Correctly compute the size of the needed memory for the datatype tests.
Fixes open-mpi/ompi#294.
