I had no choice but to use string for the map key. This is
because the only information that could be passed to the controller is a
string.
With this new architecture, persistent error lists are now possible.
* Buffer
- errorList_, addError(), : deleted
- std::map<std::string, ErrorList> errorLists_ : new member
- errorList(std::string const & type): associated accessors
* buffer_funcs.C
- bufferErrors(Buffer const & buf, TeXErrors const & terr): now needs a third errorList argument
- bufferErrors(Buffer const & buf, ErrorList const & el): deleted.
* Converter
- convert(): now needs an ErrorList argument instead of filling the Buffer errorList member directly.
- runLaTeX(): ditto

* exporter.C
- Export(): send the Buffer::errors() signal instead of calling LyXView::showErrorList() directly in lyxfunc.C
* ControlErrorList.C
- initialiseParams(): translation operation transfered here from LyXView::showErrorList().
* LyXView.C
- LoadLyXFile(): add a showErrorList("Parse") call.
- showErrorList(): simplified due to code transferred to the ControlErrorList.

TODO 1: All occurrences of "LyXView::showErrorList()" in the "kernel" should be replaced by a boost signal emission (Buffer::errors()). This signal is already connected to this showErrorList() slot.
TODO 2: The ErrorList mechanism is used wrongly in a number of place, most notably in "Converter.C". Instead of replacing the ErrorList in the "Buffer" class, the "Converter" class should maintain its own list instead and connect directly to the LyXView::showErrorList() slot.
Buffer:
* errorList_: new private member and associated access methods.
* setErrorList(): new accessor method.
* addError(): apend an error to the errorList_.
* error(): deleted.
* errors(): new boost signal, unused for now. Shall be used instead of LyXView::showErrorList().
LyXView:
* getErrorList(), addError(), errorlist_, errorConnection_: deleted.
* errorsConnection_: new boost connection for the Buffer::errors() signal.
lyx_main.C:
* LyX::exec2(): manually print all errors.
BufferView.h: remove unneeded ErrorList forward declaration.
BufferView::pimpl::menuInsertLyXFile(): delete Buffer::error() connection and add a FIXME comment
text.C: Use Buffer::addError() instead of Buffer::error() signal emission.
ControlErrorList.C: get the ErrorList from the Buffer instead of LyXView

With this change, the only difference between BufferView.h and BufferView_pimpl.h is "cursor.h" so I think it is time to merge the two classes at last.
BufferView:
* showErrorList(), getErrorList(): transfered to LyXView.
BufferView::pimpl
* addError(), showReadonly(), connectBuffer(), disconnectBuffer(): transfered to LyXView.
CutAndPaste.C: adapted to API changes
frontends/controllers/ControlErrorList.C: ditto
lyxfunc.C: ditto
git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@14458 a592a061-630c-0410-9148-cb99ea01b6c8
The performance may suffer a bit because we do the second drawing step in all cases. This could be possibly optimized out by checking the return value of the BufferView::update() method in "lyxfunc.C:1610". But it is maybe better to keep those two parts of the frontend ignorant of each other: the event handling and the drawing.
BufferView:
* needRedra(), need_redraw_: deleted.
* updateMetrics(): now public.
* update(): only do the first drawing step. Returns true if a full updateMetrics is needed before drawing on screen.
WorkArea:
* redraw(): no check on BufferView::needRedraw(), call updateMetrics() unconditionally.
* processKeySim(): uneeded "redraw()" call commented out. When/if the call to LyXView::redrawWorkArea() in "lyxfunc.C:1610" is not needed anymore, this line should be uncommented out.
