wm4 49d1b42f70 client API: add a way to notify clients of property changes
This turned out ridiculously complex. I think it will have to be
simplified some day. Main reason for the complexity are:
- filtering properties by forcing clients to observe individual
  properties explicitly
  (to avoid spamming clients with changes they don't want)
- optional retrieval of property value with the notification
  (the basic idea was that this is more user friendly)
- allowing to the client to specify a format in which the value
  should be retrieved
  (because if a property changes its type, the client API couldn't
  convert it properly, and compatibility would break)

I don't know yet which of these are important, and everything could
change. In particular, the interface and semantics should be adjusted
to reduce the implementation complexity.

While I consider the API complete, there could (and probably will) be
bugs left. Also while the implementation is complete, it's inefficient.
The complexity of the property matching is O(a*b*c) with a clients,
b observed properties, and c properties changing at once. I threw away
an earlier implementation using bitmasks, because it was too unwieldy.

wm4 98dc8206ae options: handle escape sequences in e.g. --playing-msg differently
M_OPT_PARSE_ESCAPES was pretty stupid, and broke the (useful) assumption
that string variables contain exactly the same value as set by the
option. Simplify it, and move escape handling to the place where it's
used.

Escape handling itself is not terribly useful, but still allows useful
things like multiline custom OSD with "\n".

wm4 206616b697 lua: port to client API
This is partial only, and it still accesses some MPContext internals.
Specifically, chapter and track lists are still read directly, and OSD
access is special-cased too.

The OSC seems to work fine, except using the fast-forward/backward
buttons. These buttons behave differently, because the OSC code had
certain assumptions how often its update code is called.

The Lua interface changes slightly.

Note that this has the odd property that Lua script and video start
at the same time, asynchronously. If this becomes an issue, explicit
synchronization could be added.

wm4 88ae914b1e Add a client API
Add a client API, which is intended to be a stable API to get some rough
control over the player. Basically, it reflects what can be done with
input.conf commands or the old slavemode. It will replace the old
slavemode (and enable the implementation of a new slave protocol).

wm4 a2d144fc8f m_property: mp_msg conversions
Includes some semi-crappy hacks to avoid changing too much code for this
conversion (allowing NULL log argument for m_property_do()).
