hdf5: Add mpi support

Optionally, build the parallel version of hdf5.
hdf5: Offer openmpi version of the package
hdf5: Optional enableShared flag

Required by h5py in mpi mode.
mpi4py: New package, version 1.3.1

Python wrapper for the message passing interface standard.

Currently building without mpe, or vampir-trace support.
h5py: New package, version 2.3.1

A pythonic interface to the hdf5 library. It also supports parallel hdf5.
openmpi: Optional configure flags

 * Activate support for the Sun Grid Engine
 * Pass PATH/LD_LIBRARY_PATH pointing to the current mpi installation
   to other processes by default.
krb5: explicitly giving --with-tcl=no option for configure to remove impurity
Add `--no-same-permission` to `tar` command in node package builder

This is because of an error while using `nix` under Archlinux:
```
building path(s) `/nix/store/rwkcbhv9jfhzhandfslg62knl2xw0r7m-node-sources'
building /nix/store/rwkcbhv9jfhzhandfslg62knl2xw0r7m-node-sources
suspicious ownership or permission on `/nix/store/rwkcbhv9jfhzhandfslg62knl2xw0r7m-node-sources'; rejecting this build output
cannot build derivation `/nix/store/01qsszx9y2kyx1x72zr5magy2la98720-uglify-js-2.4.15.drv': 1 dependencies couldn't be built
```

The permissions on all file are like the following:
```
drwxrwxr-x 1 root root    358 Jun  9 17:04 .
drwxr-xr-x 1 root root 421110 Jul 21 15:49 ..
-rw-rw-r-- 1 root root     22 Jun  9 17:04 .gitattributes
```
After the fix, permissions are OK, and no suspicious error any more.

Error is encountered for any node package built. I'm not sure why it
fails on Arch but work on nixos, but I believe the flag is safe to add
anyway.
updating bitcoin to 0.9.2.1
fixing whitespace
Added abduco
rsync: sha256 for the patch was updated
Changed to correct license from licenses.*
liquidfun: added google liquidfun (a box2d fork)
liquidfun: updated url and license
plan9port:
	- Update to 20140306
	- Fixed libXt dependency.  The compiler could not find X11/IntrinsicP.h, even though it is available through the nix store.  I think there must be some issue with the 9c compiler being used and not obeying the CFLAGS that nix is supposed to pass.  There are probably other dependencies I'm missing, but 9c found in my /usr/include.
plan9port: builder.sh called install script twice, meaning a redundant recompile.
Merge branch 'master' of ssh://github.com/vvanpo/nixpkgs into plan9port
nano: support system-wide nanorc

This patch does two things
1. builds nano with sysconfdir=/etc; and
2. adds an option programs.nano.nanorc
nano: bump to version 2.3.6
