This makes "sequential" more or less mean an octave vertical interval,
but only for in-key mode. For chromatic mode, "sequential" is still just a
naive wrap-around layout for every note.
This juggles the implementation slightly in a way that's more resilient to
mistakes: the representation of pads in the surfaces is always fully reset
before setting up the grid, and a state message is sent for every single pad
once after the scale algorithm sets things up.
This means that scale algorithms don't need to deal with hairy edge cases like
running off the end of the scale or the valid range of MIDI notes.
"Mostly" because there are still some issues with horizontal overlap between
entries, but I think that's something that needs to be addressed separately.
Like earlier issues, this was caused by using a screen-derived or default
cairo/pango context. I also tinkered with some constants to make things look
sensible to me, and hopefully everywhere since it should always look the same
with the context fix.

This resolves a PBD vs ARDOUR namespace error for some compilers:
```
error: reference to 'microseconds_t' is ambiguous
libs/pbd/pbd/microseconds.h:29:19: error: candidates are: typedef uint64_t PBD::microseconds_t
libs/ardour/ardour/types.h:81:29: error: typedef PBD::microseconds_t ARDOUR::microseconds_t
```
In some cases old and/or conflicting port names were saved
with the session (e.g. "Faderport" for FP1,8). Loading old sessions
then merges this state into the config, which could lead to
port-registration failure when the surfaces was enabled.
* replace signal-emission with direct calls to CoreSelecton
using BaseUI's session pointer
* remove unused leftmost strip API
* use CoreSelection for first-selected strip
* Accessing CoreSelection does not modify the session
(allow access from const callbacks)
* replace static calls in P2 surface
This removes indirection and dependency on the GUI for
managing strip selection.
Previously this was inherited via PBD.
On MacOS/X, this adds
"-undefined dynamic_lookup -flat_namespace"
and various "-framework .." options to linkflags
Without this flag, .dylibs fail to link usually because
of missing `-lintl` (Undefined symbols: "_libintl_dgettext")
On other systems this is a NO-OP:
CFLAGS_OSX, CXXFLAGS_OSX and LINKFLAGS_OSX
are only set on the darwin platform.
