* Do backslash escape parsing in parse_kv() [was being done in the copy
module purely for newlines in the copy module's content param before]
* Make parse_kv always return unicode
* Add bandaid to transform args to unicode until we can fix things
calling parse_kv to always send it unicode.
* Make split_args deal with unicode internally. Warning, no bandaid for
things calling split_args without giving it unicode (shouldn't matter
as dealt with str internally before)
* Fix copy and unarchive action plugins to not use setdefaultencoding
* Remove escaping from copy (it was broken and made content into latin-1
sometimes). escaping is now in parse_kv.
* Expect that content is now a unicode string so transform to bytes just
before writing to the file.
* Add initial unittests for split_args and parse_kv. 4 failing
tests.because split_args is injecting extra newlines.
Prevents an exception from raising in some corner cases where SSH might
be misconfigured. It seems not to fix a specific problem, although it
makes the method a little bit more solid.
We have been caching the paths to the plugins but before we would only
cache the specific plugin that we were looking for. This meant that we
might search through all of the plugin directories before finding the
specific module we were interested in. The next plugin we needed we
might again search through all the plugin directories before finding the
plugin we wanted.
This new code will cache all the potential plugins in each directory
searched. For a play that only uses one plugin we'll only search
through directories until we encounter the directory that has the proper
plugin. For a large playbook with many plugins used we'll search
through each directory at most once each.

Dynamic task includes still need some work, this is a rough first version.
* doesn't work with handler sections of playbooks yet
* when using include + with*, the insertion order is backwards
* fix potential for task lists to be unsynchronized when using the linear
strategy, as the include conditional could be predicated on an inventory
variable
