This prevents having to export those callbacks and put them in the
global namespace. Also, use inline shell script in Makefile.am instead
of a Python script which should be more portable (by default) and gets
rid of the helper script.

Checks if the compiler supports -fvisibility and the linker supports
-dynamic-list arguments and use them instead of hardcoding. The new
geany-lib.m4 also accomodates future use of Libtool versioning.

This will allow plugins to link against the core when accessing API
functions, now that the macro/struct/funcptr stuff is gone.

Also convert the helper libraries into Libtool helper libraries as
linking a shared library against static libraries is (apparently) not
portable.

Add rest of headers needed for declarations of all public API
functions. Add HAVE_PLUGINS define to geanyplugins.h since some headers
need this and it should always be valid for this header.
geanyfunctions.h left for source-level backwards compatibility for
plugins which might `#include` this header directly. I don't know why
they do it, but some Geany-Plugins do this.

It only needs to be specified in one place for each function.

This allows them to be dynamically exported when -fvisibility=hidden
is applied.

TODO: remove the CFLAGS hack in configure.ac

Adds a new header `pluginexport.h` to put the macros in, could be
moved into an existing header (support.h?) by I didn't want to drag
a bunch of existing stuff into the source files for this one macro.

TagManager has relative include, this could be fixed by changing the
include directories for it if it's a problem. Mark the Scintilla
functions exported by re-declaring them in sciwrappers.c with the
attribute to avoid changing upstream Scintilla code.

Uses a Python script to generate a listing used by the linker to
determine which symbols to dynamically export. This provides finer
grained control of which symbols are dynamically exported, limiting
only to the ones needed for GtkBuilder signal connections.

The build system integration could probably be done a little cleaner.

Enable new Scintlla lexer.cpp.verbatim.strings.allow.escapes lexer
property for ObjectiveC.

Also remove extra padding around the button's image to reduce its size
and try and avoid it expanding the tab's height.

This at least fixes the editor tabs height on Adwaita theme, where they
were 1px taller than normal.

Use the short name for EOL mode in the statusbar

Disable "rules hint" for the Documents tab

The "rules hint" property is used to tell the theme for which TreeView
even/odd rows should have a different color. This is typically used for
long rows or rows which need to be visually separated for some reason.

Currently the Documents sidebar view uses it which doesn't make much
sense because the row is short and neither of the other tabs in the sidebar
use it.

Merges PR #417.

This does not change anything in practice because static variables are
initialized implicitly as we need them anyway, but this makes things
clearer and more explicit.

Spell "Windows" as "Windows", not "Win".

Always use absolute path when opening projects from command-line

At the moment when geany project is loaded from commandline using
e.g. "geany myproject.geany", the relative path is used by geany
so e.g. Project->Recent Projects shows the relative path instead of
the absolute one (also if the project is already in the list with an absolute
path, additional entry with relative path is created).

Use main_get_argv_filename(), which is already used for ordinary files,
also for opening .geany files.

OS X integration

Create geany_run_script.sh in the temporary directory instead of the
working directory.

Fix compiler warning

The current implementation uses single menu for the toolbar and
menubar and reparents it when file menu is shown/hidden.
Connectiong "show"/"hide" signals doesn't work for menu items
on OS X (and I suppose Ubuntu either) so the template submenu is
never shown in the File menu.

The easiest fix seems to be having two identical menus the same
way we have them for recent files.

Since we have a simple way to check Geany has entered foreground
on OS X, use it to check the current document's disk status.

The expose-event/draw signals were used to reenable the menu
after it has been disabled when VTE overrides the given keybinding.
This doesn't work on OS X where GtkMenuBar isn't displayed
(there may be a similar problem with the global menubar on
Ubuntu).

The reason why these signals were used was probably slight
flickering of the menubar when using ordinary g_idle_add() to
reenable the menu (the dimmed menu gets drawn after which
it gets reenabled and redrawn non-dimmed). It is however possible
to use idle function with higher than redraw priority in which case
the menu is enabled before the redraw so the dimmed menu
isn't drawn at all.

Fixes https://sourceforge.net/p/geany/bugs/1081/

Normal clicking the launcher icon just brings the application to
the foreground so there must be a way users can create a new
instance of Geany.

Add an entry "New Window" to the context menu which is shown
when right-clicking the Geany icon in the launcher (most applications
have the "New Window" entry there).

In addition, fix "Open in new window" when using app bundle.

Since both of these functionalities create a new Geany instance,
factor-out the instance creation code into a new utility function
and use it in both cases.

NSApplicationBlockTermination signal is emitted when clicking
the Quit menu to check whether the application permits
quitting - react accordingly.

---

NSApplicationOpenFile signal is emitted when

* file is dragged on the application icon
* application is selected from "Open with" menu after right-clicking
the file
* when double-clicking a file for which the application is default
editor/viewer
* when file is opened from command-line

When the application isn't running, it is first started and then this
signal is emitted.

Use the signal to open files. In addition, when the opened file
has the ".geany" suffix, open it (but only if the project isn't already
open). The project has to be opened in idle function because blocking
the signal handler for a long time by the project-close confirmation
dialog causes problems.

We have to disable quartz accelerator handling because otherwise
accelerators are performed also from other windows than the main
Geany editor (e.g. Ctrl+V with find dialog open performs the keybinding
Ctrl+V and inserts the text to the editor).

OS X applications have an extra menu entry to the left of the File menu -
an "application menu". This menu usually contains About, Preferences,
Quit. Many users, however, may be used to Geany from other platforms
and expect Preferences to be under the Edit menu so leave them there.
Quit and About are rarely used and the application menu is the place where
they are supposed to be - move these entries from other Geany menus there
and hide them in the affected menus (the quit entry is inserted automatically,
we just need to hide it from File).

Also tell OS X the Help menu is dedicated to help (we get search in
menu entries by name for free thanks to this).

The global menu should refresh automatically based on user actions.
Unfortunately this is not the case when gtk_menu_reorder_child()
is used because it does not emit any signals so the gtk-mac-integration
library doesn't see this call. Refresh the menu manually after calling
this function.

This patch adds the gtk-mac-integration library and uses it to
adjust various paths in Geany to point it inside the app bundle
if Geany runs from inside the bundle.

It adds the utils_resource_dir() utility function to return
correct directories for various kinds of resources for all supported
operating systems. Using this function the patch adjusts all Geany
resource, plugin, icon, doc, and locale paths.

Under some conditions, geany_run_script.sh is not deleted and we
have no means to detect this in Geany (e.g. when the terminal emulator
is started correctly but it fails to execute the script for some reason).
In this case it is better to keep the garbage in /tmp than the working
directory. Apart from that, it eliminates potential transfer of the run script
over a NFS and eliminates the visibility of the script in working directory
on Windows.

Apart from that this patch fixes some locale/utf8 conversion problems
and other subtle problems with the previous implementation.

Closes https://sourceforge.net/p/geany/patches/10/

Fix installation of data files on Windows with the Autotools build
system.

Most of our tree view tooltips were set from plain text values but
parsed as markup by GTK, which sometimes lead to markup errors, when
the tooltip value contained markup control characters.

This also adds ui_tree_view_set_tooltip_text_column() to the plugin
API so plugins can easily set plain text tooltips from tree views
columns.
