Reduce reliance on boost - the hard part 
the rest from `tools/convert_boost.sh`.

* replace boost::function, boost::bind with std::function and std::bind.

This required some manual fixes, notably std::placeholders,
some static_casts<>, and boost::function::clear -> = {}.

968533cc23 (re)add mechanism for a callback in any glib event loop executed before the loop "executes" 
This is based on code from earlier commits that were later reversed, but we need some mechanism
to ensure that threads have a thread local tempo map ptr set. The big difference is that this
time we do not implement this for all instances of an AbstractUI - implementation is left to
each thread/event loop

Fix BaseUI x-thread signal vs thread-start race 
Control surfaces c'tor usually subscribe to signals e.g.
PortConnectedOrDisconnected. This happens after the parent BaseUI
is created, but before set_active() -> BaseUI::run() is called.

At this point in time there is no run_loop thread.

There are two options to handle AbstractUI::call_slot():

 A. Queue the event in the event-loop, using the thread-local
    request buffer of the caller. Then hope the BaseUI
    thread is started, and calls ::handle_ui_requests() before
    the memory pool runs out of space.

 B. Handle the event in the calling thread. -- This may not be
    rt-safe and may call functions with locks held by the caller.
    It will however not accumulate events.

This takes approach (B). If _run_loop_thread is NULL, directly
handle the signal.

In the past, prior to 50abcc74b5, approach (A) was taken.
NULL never matched Glib::Threads::Thread::self().

This also reverts a prior attempt (e417495505) to address this issue.

Fix possible race (BaseUI creation vs x-thread signal-emission) 
When a BaseUI is being created, signals can arrive before the
_run_loop_thread is running, which can trigger an assert in
BaseUI::caller_is_self().

4adb2f97cc Use timeout source to process ui requests on windows 
Using a timeout source to process ui events/requests is suboptimal
but it works for the moment. Have to use g_source functions as glibmm
functions are not thread safe AFAIK.

Behaviour should be exactly the same on unix.

1e0fd01815 drop boost::signals2 and replace with carl's solution which continues to rely on boost::function and boost::bind but alters two important semantics of signals2: (1) when a Connection object is disconnected, the slot ("functor") associated with the connection is destroyed immediately, unlike signals2 where this is deferred to a subsequent connect/emit call on the signal (2) if one functor called by the signal disconnects another Connection, the functor represented by the Connection will NOT be called during the current signal emission (signals2 copies the slot list at the start of emission and calls everything in the slot list). this change fixes some very nasty crashes apparently caused by boost::signals2 assuming that the memory referenced by a functor remains valid after a disconnect (google will show other developers who had issues with this).

e0aaed6d65 *** NEW CODING POLICY *** 
All #include statements that include a header that is a part of a library
bundled with ardour MUST use quotes, not angle brackets.

Do this:

#include "ardour/types.h"

NOT this:

#include <ardour/types.h>

Rationale:

This is best practice in general, to ensure we include the local version
and not the system version.  That quotes mean "local" (in some sense)
and angle brackets mean "system" (in some sense) is a ubiquitous
convention and IIRC right in the C spec somewhere.

More pragmatically, this is required by (my) waf (stuff) for dependencies
to work correctly.  That is:

!!! FAILURE TO DO THIS CAN RESULT IN BROKEN BUILDS !!!

Failure to comply is punishable by death by torture. :)

P.S. It's not that dramatic in all cases, but this (in combination with some
GCC flags specific to the include type) is the best way I have found to be
absolutely 100% positive the local ones are being used (and we definitely
want to be absolutely 100% positive on that one).
