Bjørn Forsman c9baba9212 Fix many package descriptions
(My OCD kicked in today...)

Remove repeated package names, capitalize first word, remove trailing
periods and move overlong descriptions to longDescription.

I also simplified some descriptions as well, when they were particularly
long or technical, often based on Arch Linux' package descriptions.

I've tried to stay away from generated expressions (and I think I
succeeded).

Some specifics worth mentioning:
 * cron, has "Vixie Cron" in its description. The "Vixie" part is not
   mentioned anywhere else. I kept it in a parenthesis at the end of the
   description.

 * ctags description started with "Exuberant Ctags ...", and the
   "exuberant" part is not mentioned elsewhere. Kept it in a parenthesis
   at the end of description.

 * nix has the description "The Nix Deployment System". Since that
   doesn't really say much what it is/does (especially after removing
   the package name!), I changed that to "Powerful package manager that
   makes package management reliable and reproducible" (borrowed from
   nixos.org).

 * Tons of "GNU Foo, Foo is a [the important bits]" descriptions
   is changed to just [the important bits]. If the package name doesn't
   contain GNU I don't think it's needed to say it in the description
   either.

longDescription = ''
hwloc provides a portable abstraction (across OS,
versions, architectures, ...) of the hierarchical topology of
modern architectures, including NUMA memory nodes, sockets,
shared caches, cores and simultaneous multithreading. It also
gathers various attributes such as cache and memory
information. It primarily aims at helping high-performance
computing applications with gathering information about the
hardware so as to exploit it accordingly and efficiently.
hwloc may display the topology in multiple convenient
formats. It also offers a powerful programming interface to
gather information about the hardware, bind processes, and much
more.
