Removed a configure dependancy on SOX for IIO.

Removed a spurious initOK label in the driver_initialize function.

Added the codeBlocks key to the .gitignore file.

Added my name and those who helped me to the Changelog file.
Implemented various changes from a second code review by Stéphane;
JackIIODriver::Attach is now JackIIODriver::Open.
JackIIODriver::Detach is now JackIIODriver::Close.
driver_initialize now uses 'goto' on error to reduce replication.

No functional change, only whitespace.

This commit is based on Matt Flax's commits, just slightly polished and
split into logical blocks.

I did not review the code itself, since Stephane has already accepted
Matt's sequence into the codebase, thus indicating he's fine with the
changes.
