Three actions have been added to the main View menu (Guesses submenu)
in order to easily change the number of Guesses displayed.

Guesses > Show more (alt - +)        [shows 5 more guesses]
          Show fewer (alt - -)       [shows 5 fewer guesses]
          ---
          Reset to default (alt - 0) [resets to 5 guesses]

Motivation behind this commit is that in large UIs with thousands
of strings, 5 guesses are not enough in some situations to gather
all the information necessary to correctly translate a string.

Now it is possible to search using a Perl-like regular
expression. This enables the user to perform powerful
searches. There are many scenarios in which this is
convenient, let me show an example:

Source (Eng)     | Translation (Spa)
------------------------------------
From               Desde
From               De
... from ...       ... de ...
... of ...         ... de ...
from 1 to 10       de 1 a 10
(plus many other strings also containing "de" or "desde")

Even simple Regular Expressions like
^Desde$
^De$
from \d+ to \d+
become very convenient for fine-grained searches.

If the regular expression written in the Find Dialog
is not valid, text is highlighted in red and Find
button is disabled.

Linguist shows the number of finished units and the number of editable
units in the lower right corner of the window (e.g.: 6714/6833).
It also shows this completion progress number per context.

With this change, it displays the difference between these numbers
in a tooltip (i.e. hovering the mouse on the count 6714/6833), for
both global progress count and per context progress count.

While this change may be arguable, the remaining count is the number
that a translator tracks and is constantly checking, other numbers
are less relevant. This small change improves User Experience since
the translator doesn't need to use a calculator or do a mental
calculation, which takes time and may also lead to miscalculations.

Context for each Guess entry from "Phrases and guesses" is shown.
This is quite convenient since context provides valuable information.
Same source phrase could be in different contexts and the translation
for each of them can be potentially different.

For example, it would be useful in this situation (English-Spanish):

Source phrase | Translation | Definition
Add             Añadir        Guess from 'ButtonToolbar' (Ctrl+1)
Add             Sumar         Guess from 'CalculatorDialog' (Ctrl+2)
Addition:       Ampliación:   Guess from 'SizeEditorDisplay' (Ctrl+3)

This is more helpful than:

If qgetenv() doesn't return a valid environment variable, try querying

This is useful for projects outside Qt, as it allows using e.g.
QT_INSTALL_DOCS and QT_INSTALL_HEADERS. The former can be used for
accessing the Qt documentation template, and the latter is useful for
projects that need to pass Qt's include paths to Clang (which QDoc
uses for parsing C++ documentation). The build system doesn't
provide these paths when trying to build docs for a module that
doesn't build on the host platform; for example, building Active Qt
documentation on Linux.

A class node must have pointers to the class nodes of its base classes, but these
pointers might not exist when qdoc creates the class node for the class. They might
not exist until all the index files and include files have been parsewd. qdoc was
trying to resolve the base classes too early. This update lets qdoc wait until it
is known that everything has been built before attempting to resolve inheritance.

This update also delays finding the pointer to the function node for the overridden
function for a function marked "override" until the pointer is needed. Instead of
storing the pointer to the node, the qualification path to the function is stored
as a string, and the string is used to look up the overridden function when it is
needed, which is only when the \reimp command is processed during output.

The function that resolves the pointer to the overridden function was moved to the
function node class, where it makes more sense. The way a few qdoc warnings are
reported was also changed.
