Add a widget derived from GtkDrawingArea that handles the drawing. It
automaticaly requests rerendering of the page if necessary (i.e on a scroll and
rotate).
This should solve all the rendering issues.
The patch fixes the following build warnings:
zathura.c: In function ‘prepare_document_open_from_stdin’:
zathura.c:306: warning: implicit declaration of function ‘close’
zathura.c:314: warning: implicit declaration of function ‘read’
zathura.c:316: warning: implicit declaration of function ‘write’

We need to know the document's 'scale' value earlier (before cairo
surfaces are created). Otherwise, cairo surfaces will be re-created and
wrong page will be rendered (since zoom doesn't preserve page number).

It never returns NULL. If this function fails, the application is
terminated.

Currently, zathura crashes while performing ':close' command with the
following error:
GThread-ERROR **: file gthread-posix.c: line 226
(g_cond_free_posix_impl): error 'Device or resource busy' during
'pthread_cond_destroy ((pthread_cond_t *) cond)'
The error is because 'render' thread holds condition variable while
waiting for new pages to render. This patch modifies zathura's code to
correctly kill render thread and free allocated resources when the
document is being closed.
NOTE: should be applied on top of "Allow changing of "pages-per-row"
variable at runtime" commit to avoid conflicts in the
'page_view_set_mode()' function.
