Avoid crashes when passing an invalid location to a
gtk_text_buffer_get_iter_at_*() function.
A first attempt added boolean return values to know if @iter has been set to
the exact location, but it breaks Python and JS bindings because the out
parameter is already a return value in those languages.
Unit tests are added.

This reverts commit a9a1c00cc9.
Unfortunately, adding the boolean return broke both the python
and javascript bindings, since they now return a tuple consisting
of the boolean and the out argument.
Avoid crashes when passing an invalid location to a
gtk_text_buffer_get_iter_at_*() function.
A boolean is returned to know if @iter has been set to the exact
location.
Unit tests are added.

This commit adds the GtkTextTag:underline-rgba and :strikethrough-rgba
properties and the necessary plumbing to apply these colors in GtkTextLayout.
With this change, you can alter the color of underlines including those
of type PANGO_UNDERLINE_ERROR.
You might want to alter the underline color to differentiate between
spelling and grammer mistakes. In code editors, it is convenient to
differentiate between errors and warnings.
Note that the GtkTextAppearance struct is public ABI and has no spare
room for new fields, so we are resorting to some tricky packing to store
the colors in the unused pixel field of the fg_color and bg_color structs.
This packing is accomplished by the macros in gtktextattributesprivate.h.

NULL was returned in case of an empty last line. Every users needed to
special-case this. Now it will return the expected result: char_len of 0
with one PangoLogAttr.
In compute_log_attrs(), 'paragraph' will be the empty string "" with
'char_len' == 0.
pango_get_log_attrs() works fine with an empty string, it will return
one correct PangoLogAttr (because there is one text position for the
empty string).
It fixes the unit tests for gtk_text_iter_is_cursor_position().

- only one blank line is enough to separate code sections.
- the 'signals' variable was in the middle of function prototypes.
- compare pointers to NULL in some conditions ("if(blah) should be used
only if blah is a boolean variable). It makes the code clearer.
- various other things.
Although there is the "changed" signal, it is more correct to notify the
"text" property too. It can be useful for a small text view, where the
text is saved e.g. to gsettings with a binding to the text property.
The "text" property includes only the text, not child widgets or images,
so the notify signal is sent too many times (also for child widgets and
images), but it's not a big problem.

This is expected to happen on wayland and other platforms with no primary selection,
and just leads to the selected text being cleared after any attempt to change the
text selection itself through either mouse/keyboard.
Returns NULL in case of a duplicated tag name in the tag table. It is
still a programmer error to duplicate a name, but if it happens the
behavior is a little nicer (and hopefully doesn't crash).

It is more logical to first delete the selection and then pasting the
text. When the selection and the text contain tags, the new behavior is
more natural.
A segfault in paste_from_buffer() is also avoided. The segfault occurs when
the text to paste is deleted because it is the selection.

Move GtkWrapMode from GtkTextTag to the GtkTextView section. The wrap
mode property is in the text view.
Links to the "mark-set" and "mark-deleted" signals.
Add a precision about gtk_text_buffer_get_iter_at_line().
Fix typo in gtk_text_tag_set_priority().

For gtk_text_iter_get_char(), due to the "Returns" at the beginning of
the description, the description was not visible. So the first sentence
has been reworded.
