Subject: [PATCH 1/2] cmake: s/ICONV/Iconv/ in FIND_PACKAGE

The cmake module we provide is in the file FindIconv.cmake,
so we must match the case correctly. It happens to work in
practice because we only turn on ICONV on Darwin, and people
generally have case-insensitive filesystems there.

Note that we only need to update the package name here. The
package itself still sets the all-uppercase ICONV_FOUND
flag, so we continue to use uppercase in the rest of cmake.

Subject: [PATCH 2/2] examples: add a basic for-each-ref example

This is quite close to running "git for-each-ref" except:

  1. It does not take any formatting or selection options at
     all.

  2. The output is not sorted.

I wrote it to look at debugging some issues with ref
iteration, but there's no reason it can't live on as an
example command.
