.mailmap: Map email addresses to names

.mailmap: Map email addresses to names

People change email addresses quite often and sometimes forget to
add their entry to the mailmap file.  I have contacted lots of
people, whose name occurs multiple times in the short log having
different email addresses. The entries in the mailmap of this patch
are either confirmed by them or are trivial.  Trivial means
different capitalisation of the domain (@MIT.EDU and @mit.edu) or
the domain was localhost, (none) or @local.

Additionally to adding (name, email) mappings to the .mailmap file,
it has also been sorted ("LC_ALL=C /usr/bin/sort", byte-value sort).

While the most changes happen at the email addresses, we also have a
name change in here. Karl Hasselström is now known as Karl Wiberg
due to marriage. Congratulations!

To find out whom to contact I used the following small
script:

    #!/bin/bash
    git shortlog -sne |awk '{ NF--; $1=""; print }' |sort |uniq -d > mailmapdoubles
    while read line ; do
        # remove leading whitespace
        trimmed=$(echo $line | sed -e 's/^ *//g' -e 's/ *$//g')
        echo "git shortlog -sne | grep \""$trimmed"\""
    done < mailmapdoubles > mailmapdoubles2
    sh mailmapdoubles2
    rm mailmapdoubles
    rm mailmapdoubles2

Also interesting for similar tasks are these snippets:

    # Finding out duplicates by comparing email addresses:
    git shortlog -sne |awk '{ print $NF }' |sort |uniq -d

    # Finding out duplicates by comparing names:
    git shortlog -sne |awk '{ NF--; $1=""; print }' |sort |uniq -d
