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().

For functions using _gtk_text_buffer_get_line_log_attrs():
- gtk_text_buffer_backspace()
- some gtk_text_iter functions (word/sentence/cursor boundaries)
As the FIXME comments show, there is a bug with
gtk_text_iter_is_cursor_position() for an empty last line.

find_by_log_attrs() can return true only in this case:
return moved && !gtk_text_iter_is_end (arg_iter);
So if the iter moved (i.e. something has been found), but is the end
iter, find_by_log_attrs() returns false.
Now the same checks are made in find_visible_by_log_attrs(). The public
functions using find_visible_by_log_attrs() say in their documentation
that false is returned for the end iter, hence the check with
gtk_text_iter_is_end().

attrs[len] is the last PangoLogAttr available, at the iter position after the
last character of the line.
For a line in the middle or the start of the buffer, the '\n' is taken
into account by 'len'. For example the is_word_end is generally reached
before the '\n', not after. But for the last line in the buffer, where
there is no trailing '\n', it is important to test until attrs[len].
The bug didn't occur before because find_by_log_attrs() worked directly
on the iter passed as the function argument. But now it is no longer the
case.
https://bugzilla.gnome.org/show_bug.cgi?id=618852
Do not work with the iter passed as the function argument. Work with
another iter, and set it back to the function argument only if something
has been found.
This fixes a few unit tests. But there are regressions for a few others.
https://bugzilla.gnome.org/show_bug.cgi?id=618852
- As the tests show, some of the functions have a strange and
inconsistent behavior for corner cases.
- Rename test_full_buffer() -> test_search_full_buffer() because
textiter.c is used for other GtkTextIter unit tests.

When the search is case sensitive, g_utf8_normalize() is not called, so
the skip_decomp argument of the function forward_chars_with_skipping()
must be FALSE.
To verify that, when searching "éb", the count parameter of
forward_chars_with_skipping() have a different value:
- case sensitive: count = 2
- case insensitive: count = 3 (g_utf8_normalize() has been called)
The commit adds unit tests that didn't pass before, and that now pass
(without known regression, obviously).

The function must return TRUE only if there is a tag toggle _after_ the
iter, not _at_ the iter. So for the end iter, the function must always
return FALSE.
Add also unit tests for gtk_text_iter_forward_to_tag_toggle().
