Add a package for ant, a java build tool.

Add a package that installed the pre-built maven distribution.

I've given up, for now, on building maven from source.  That processed
stumbled on two points before I gave up:

1. It downloaded several hundred .{pop,jar} files and I despaired of
   figuring out some way of mirroring and checksumming them; and

2. It exploded complaining about too many unacceptable license files,
   which seems odd in its own source tree.

Perhaps someone with more Java fu that I admit to can figure it out.
In the meantime, this is useful.

* libsodium: add latest versions, fix old versions

older versions of libsodium were added to an "old" subdirectory

prerequiste for the latest develop version of flux

Pkg-config depends on glib which depends on pkg-config. As a result,
pkg-config used to build glib internally. However, this fails on Mac.
Building pkg-config with an internal glib is now a variant, turned on
by default, and required to build glib.

* Add patch allowing GCC 6 to compile GCC 5

* Expand patch version range

* Tells boost explictly about libraries and headers

Ideally, bjam would determine the libraries and headers from the
executable. But it doesn't. This rigs a best guess for python libraries
and headers.

* Move glob import to top of file

* variable name change: alllibs --> all_libs

* Use dso suffix rather than hard-coded string

* Use only MAJOR.MINOR when setting up python in bjam

do_install : allow for an arbitrary number of phases

* Fixed a bug causing config-specified compiler flags to be ignored.
Updated the compiler config so all flags are in a separate section.

* Updated the documentation for the `compilers.yaml` file spec.

* Implemented basic testing for the 'flags' section of compiler config.

* Fixed a few minor problems with the manual compiler config documentation.
