fixes #383

`pip` will install `setuptools` automatically.

pyenv-version-file-read: use sed instead of type/head/awk

Improve `pyenv version`, if there is one missing

pip-rehash: handle versions in commands, like "pip2" and "pip3.4"

I was seeing the following occasionally in scripts:

> …/.pyenv/libexec/pyenv-version-file-read: line 12: type: write error: Broken pipe

This patch hopefully improves/fixes this, and it seems better anyway to
just use sed here.

Fix test for adding shims in fish

This seems to have not been merged properly.

A similar issue is with the test for fish, which has been submitted as a
PR for rbenv: https://github.com/sstephenson/rbenv/pull/722.

Commit e2173df4 (for issue #369) did not handle the fish test properly.

This renames it and fixes the assertion.

Merge rbenv to have a common ancestor for future merges

Details on multiple Python2 and Python3 versions.

Add detail regarding activating multiple Python2 and Python3 versions simultaneously.

This merges
4d72eefffc
to build a common ancestor for future merges.

This is branched off f48a5b11d709ec616f766864b8e0ab894cb30962, which was
the last manual merge.

Discussion / initial idea: https://github.com/yyuu/pyenv/pull/286#issuecomment-66565475

This was done using:

    # Keep our changes for "unmerged, both added"
    for i in $(git status --porcelain | grep '^AA ' | cut -d\  -f2); do
      git checkout --ours $i
      git add $i
    done

    # "git mv" rbenv files to our name, keeping the current contents.
    for i in $(git status --porcelain | grep '^A ' | sed 's/^A  //'); do
      ours=${i//rbenv/pyenv}
      test -f $ours || { echo "Skipping: $i"; continue; }
      git mv -f $i $ours
      git reset HEAD $ours
    done

I've handled the following then manually:

    - rbenv.d/exec/gem-rehash.bash
    - rbenv.d/exec/gem-rehash/rubygems_plugin.rb

This should allow to merge rbenv in the future using:

    git merge rbenv/master -s recursive -X rename-threshold=5%

I am not sure about the rename-threshold, 25% also worked for one file
I've tested.
