Add simple combined exe build for mupdf/muxps tools.

Move to a non-pdf specific type for links. PDF specific parsing is
done in pdf_annots.c as before, but the essential type (and handling
functions for that type) are in a new file fitz/base_link.c.
The new type is more expressive than before; specifically all the
possible PDF modes are expressable in it. Hopefully this should
allow XPS links to be represented too.

Firstly, we rename pdf_store to fz_store, reflecting the fact that
there are no pdf specific dependencies on it.
Next, we rework it so that all the objects that can be stored in
the store start with an fz_storable structure. This consists of
a reference count, and a function used to free the object when
the reference count reaches zero.
All the keep/drop functions are then reimplemented by calling
fz_keep_sharable/fz_drop_sharable. The 'drop' functions as supplied
by the callers are thus now 'free' functions, only called if
the reference count drops to 0.
The store changes to keep all the items in the store in the linked
list (which becomes a doubly linked one). We still make use of
the hashtable to index into this list quickly, but we now have
the objects in an LRU ordering within the list.
Every object is put into the store, with a size record; this is
an estimate of how much memory would be freed by freeing that
object.
The store is moved into the context and given a maximum size;
when new things are inserted into the store, care is taken to
ensure that we do not expand beyond this size. We evict any
stored items (that are not in use) starting from the least
recently used.
Finding an object in the store now takes a reference to it already.
LOCK and UNLOCK comments are used to indicate where locks need to
be taken and released to ensure thread safety.

draw_simple_scale.c is a cut down version of draw_scale.c, that only
uses filter functions that return values strictly in the 0 to 1 range.
Because of that, we can use bytes rather than ints as intermediate
storage, and have no clipping to do.

This frees us from passing errors back everywhere, and hence enables us
to pass results back as return values.
Rather than having to explicitly check for errors everywhere and bubble
them, we now allow exception handling to do the work for us; the
downside to this is that we no longer emit as much debugging information
as we did before (though this could be put back in). For now, the
debugging information we have lost has been retained in comments
with 'RJW:' at the start.
This code needs fuller testing, but is being committed as a work in
progress.

Huge pervasive change to lots of files, adding a context for exception
handling and allocation.
In time we'll move more statics into there.
Also fix some for(i = 0; i < function(...); i++) calls.

pdf/data_encodings.h and pdf/data_glyphlist.h were added without adding them
to the solution.

Also turn on font hinting when rendering non-aa text.
|
|
Update the text rendering code to use the raster renderer in freetype rather
than the smooth one. No change to the hinting methods used yet.

Add fz_bitmaps (1bpc versions of pixmaps, really).
Add fz_halftones (arrays of fz_pixmaps used as threshold arrays).
Add simple halftoning code.
Add pdfdraw usage of the above (ask for a .pbm and you get a halftoned image).

reverse is not true). Update projects to reflect recent movement in files.

The run-together words are dead! Long live the underscores!
The postscript inspired naming convention of using all run-together
words has served us well, but it is now time for more readable code.
In this commit I have also added the sed script, rename.sed, that I used
to convert the source. Use it on your patches and application code.
