add UDP protocol support for logger

When a syslog daemon fails and SysLogHandler cannot reconnect to
it, server processes (proxy, container, object, and more)
would start consuming 100 % CPU and stop responding to requests.
It is because the server process go into an infinite loop if they
fail to reconnect to /dev/log.
This problem happens only when using unix_sockets.

This change enables us to use syslog without unix_sockets and fixes bug 780025.

Remove ambiguity in memcache_servers documentation

The documentation could be understood like the following:
memcache_servers from memcache.conf is always used if set, even if
memcache_servers in proxy-server.conf is set.

This is clearly not the case, as proxy-server.conf has a higher priority
if it memcache_servers is set there.

Made ranged requests on large objects working correctly when size of manifest file is not 0 byte.

Fixed bug 969411

Ranged GET request checked wheter the object is large objects only when response is 416 Requested Range Not Satisfiable.

All ranged GET requests should check the object is large object or not because size of the manifest file can be larger than 0.

Fixed bug 1011636 with segmented objects

The X-Object-Manifest header value should be url encoded to allow for
"special" characters to be used. This fix decodes such encoding. A
corresponding fix to python-swiftclient (and any other clients) needs
to be made to url encode the header value when sending.

I also fixed any pep8 1.3.1 violations I found in the test I modified
to verify this.

Validate devices and partitions to avoid directory traversals

swift.common.utils.validate_device_partition is a new function to check
that a device and a partition are valid. This means that they don't
contain '/' and are not '.' or '..'.

We use this new function every time we get devices and partitions from a
request.

Updated probe tests

The probe tests were woefully out of date with all the changes that
have ocurred since they were written. I've updated most of them and
removed some that are hopeless outdated.

I also greatly improved the timing issues (hopefully completely
solved them? I ran them 25 times with no problems) and made them pep8
1.3.1 safe.

Adapt Swift for WebOb 1.2

Based on PatchSet 3 of https://review.openstack.org/#/c/7569/ , make them to pass all funcional tests with both webob 1.x and 1.2.

The additional following compatibility issues were addressed:
 - Until patch for range header issue is merged into official webob release, testRangedGetsWithLWSinHeader() should skip test against webob 1.2
(https://github.com/Pylons/webob/commit/49c175aec2b5c134511dfea6564bfb1d37ab23a9)

 - common.constraints.check_utf8() can accept both utf8 str and unicode.
