Added a missing require to webrick/rest.rb.

Replaced 106806 occurances of ^( +)(.*$) with

The ruby community almost universally (i.e. everyone but Luke, Markus, and the other eleven people
who learned ruby in the 1900s) uses two-space indentation.

3 Examples:

    The code:
        end

        # Tell getopt which arguments are valid
        def test_get_getopt_args
            element = Setting.new :name => "foo", :desc => "anything", :settings => Puppet::Util::Settings.new
            assert_equal([["--foo", GetoptLong::REQUIRED_ARGUMENT]], element.getopt_args, "Did not produce appropriate getopt args")

    becomes:
        end

        # Tell getopt which arguments are valid
        def test_get_getopt_args

          assert_equal([["--foo", GetoptLong::REQUIRED_ARGUMENT]], element.getopt_args, "Did not produce appropriate getopt args")

    The code:
            assert_equal(str, val)

            assert_instance_of(Float, result)

        end

        # Now test it with a passed object
    becomes:
          assert_equal(str, val)

          assert_instance_of(Float, result)

        end

        # Now test it with a passed object
    The code:
        end

* Replaced 704 occurances of (.*)\b([a-z_]+)\(\) with \1\2

  3 Examples:

      The code:
          ctx = OpenSSL::SSL::SSLContext.new()
      becomes:
          ctx = OpenSSL::SSL::SSLContext.new
      The code:

* Replaced 31 occurances of ^( *)end *#.* with \1end

  3 Examples:

      The code:

      becomes:

      The code:
          end # Dir.foreach
      becomes:
          end
      The code:
          end # def
      becomes:
          end

* Replaced 6 occurances of (while .*?) *do$ with

  The do is unneeded in the block header form and causes problems
  with the block-to-one-line transformation.

  3 Examples:

      The code:
          while line = f.gets do
      becomes:
          while line = f.gets
      The code:
          while line = shadow.gets do
      becomes:
          while line = shadow.gets
      The code:
          while wrapper = zeros.pop do
      becomes:
          while wrapper = zeros.pop

* Replaced 19 occurances of ((if|unless) .*?) *then$ with

  The then is unneeded in the block header form and causes problems
  with the block-to-one-line transformation.

  3 Examples:

      The code:
          if f = test_files_for(failed).find { |f| failed_trace =~ Regexp.new(f) } then
      becomes:
          if f = test_files_for(failed).find { |f| failed_trace =~ Regexp.new(f) }
      The code:
          unless defined?(@spec_command) then
      becomes:
          unless defined?(@spec_command)
      The code:
          if c == ?\n then
      becomes:
          if c == ?\n

* Replaced 758 occurances of

      ((?:if|unless|while|until) .*)
          (.*)
      end

  with

  The one-line form is preferable provided:

      * The condition is not used to assign a variable
      * The body line is not already modified
      * The resulting line is not too long

  3 Examples:

      The code:
          if Puppet.features.libshadow?
              has_feature :manages_passwords
          end
      becomes:
          has_feature :manages_passwords if Puppet.features.libshadow?
      The code:
          unless (defined?(@current_pool) and @current_pool)
              @current_pool = process_zpool_data(get_pool_data)
          end
      becomes:
          @current_pool = process_zpool_data(get_pool_data) unless (defined?(@current_pool) and @current_pool)
      The code:
          if Puppet[:trace]
              puts detail.backtrace
          end
      becomes:
          puts detail.backtrace if Puppet[:trace]

This patch allows the puppetmaster to serve file chunks by chunks without
ever reading the file content in RAM.
This allows serving large files directly with the master without impacting
the master memory footprint.

This was an API compatibility problem with mongrel's HTTPResponse.start()
method between Mongrel 1.0.x and 1.1.x (the number of parameters changed).
The older version does not provide the option to set the response header
message which was used (redundantly with the response body) to return the
error message when the HTTP response was signaling an error.

In order to suport the older version the call was wrapped with a fallback
and the coresponding code in the other rest implementations was adjusted
to always send the error message in the response body.  Then the rest
terminus was adjusted to pull the message from the response body (if it
is present) rather than from the header (which is only used as a fallback
for dealing with older puppetmasters), and the tests were augmeted to
verify this behaviour.

There were two problems:
 * server->client communications is using Content-Type with the
direct format name instead of the format mime-type.
 * client->server communications is not using Content-Type to
send the format of the serialized object. Instead it is using the
first member of the Accept header. The Accept header is usually
reserved for the other side, ie what the client will accept
when the server will respond.

This patch makes sure s->c communication contains correct Content-Type
headers.

This patch also adds a Content-Type header containing the mime-type of
the object sent by the client when saving.

This commit includes multiple, related changes, all
in one commit because the whole thing was necessary to
reach a functional tree again:

* The URI starts with the environment, so:
  /production/certificate/foo
  /development/file_content/path/to/your/file
* All REST handling is done by a single instance mounted
  at / for webrick and Mongrel, rather than having individual
  instances mounted at, say, /certificate.
* All REST URI translation is done by an API module.  Currently
  only the 'v1' module exists with no support for additional modules,
  but it's well-separated and will be easy to expand as we need it.

We previously only handled simple strings as values,
but we know handle true and false as booleans, we URI-escape
all strings, and we can yaml-encode and then escape arrays of
strings.

This could get abused a bit, in that we're just yaml-dumping anything
that's an array, but it should be pretty safe.  Mmmm, should.
