app_server: keep pinned fonts accessible by ID after removal

On font removal styles may still be referenced by views, pictures or
whatever else. In that case, what we were doing had the following
effects:
- The style is still available through the family. So it is still
returned when listing fonts.
- The style is not available by ID. So a few app server messages will
fail, including those for string width or character escapements.
Moreover, if the removal was due to an update, adding the style again
fails because we already have one by that name. If all the old
references are finally dropped, we end up without the old nor the
updated style.

We now do the opposite: until all references are dropped, a style can
still be fetched by ID (that is, by an object that loaded it before
being removed), but it is not listed anymore (so it won't be given to an
app loading a font by name or by changing the style of a font of the
same family).

BFont: allow loading of user fonts from disk or memory

This patch adds an API call to BFont, called LoadFont, that
takes a string path to a font file. The user fonts are managed
via a new class called AppFontManager that inherits from the base
class FontManagerBase but adds the methods to add and remove user
fonts from disk or memory. There is also a new method called UnloadFont
to remove a user font, but on exit of an app all user fonts should be
automatically cleaned up.

Global/system fonts are managed by the GlobalFontManager, which is
a new class that also inherits from the base class FontManagerBase,
replacing the old "FontManager" class.

A maximum of 128 user fonts may be loaded, and memory fonts
may not exceed 20MB.

There's also an overloaded version of LoadFont that accepts
an area_id and loads the font from memory. A size and offset may
optionally be provided to allow for an area that contains more
than just a font.
