app_server: FontStyle lifecycle

FontFamily is babysitted by the FontManager. It doesn't own FontStyle
references, there's no place in it to release them.

FontManager owns a reference to the FontStyle, and it is in
fStyleHashTable. Putting a style there acquires a new reference, so we
can release the one from the new style. Removing a style from the map
releases the reference. We need to clear the map before shutting down
FreeType to get rid of our last references and let the styles die now
instead of afterwards to avoid double freeing the faces.

These solve the new crash from the previous patch. It didn't crash
before because even after the map was destroyed there were still
dangling references to the styles.

On removing a user font, the style will remove itself from the family
through the manager if that was the last reference, and the manager will
remove and delete the family if it has no more styles.

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.

app_server: Scan fonts in the looper thread.

This way, the first unlucky application to request the font list

app_server: Remove TODO comment from B_NODE_MONITOR handling.

As far as I can tell, this TODO has been resolved since 3 hours after
it was added in 2005, when the second case of B_ENTRY_REMOVED (i.e.
single-file removal instead of whole-directory removal) was implemented.
_RemoveDirectory does not appear to be fully implemented, though;
but it has its own TODO and does not need this one.

app_server: Add default case for FontManager::MessageReceived.

use .IsSet() instead if .Get() != NULL

Revert "Revert "Switch from DejaVu to Noto font""

This reverts commit 2423ba84701f064cb78a40010113a8a45cc02a92.

Revert "Switch from DejaVu to Noto font"

This reverts commit 945566ff43583e4f8102b4440c88f53dae775cb4.

As discussed on the mailing lists and with Humdinger off-list:
* The general design concensus tends slightly towards DejaVu, as metrics
of DejaVu look much better (DejaVu 12 and Noto 13 are roughly the same size,
but Noto has much wider margins with that)
* While Noto does have a wider set of fonts with support for lots of
different languages, DejaVu actually has built-in support for more
Unicode languages (the default Noto has, as far as I can tell, only
Latin/Greek/Cyrillic [2416 glyphs], while DejaVu also has Armenian, Georgian,
and a few other scripts too [5119 glyphs].)
* The worse rendering of DejaVu appears to have been somewhat rectified by
disabling the average-based subpixel filter in app_server.

Switch from DejaVu to Noto font

As discussed, Noto renders much better with freetype 2.7 [1].
The DejaVu package is still in the HaikuPorts repo and can be installed
manually just like all the other available fonts.

app_server: Fixed/documented uses of new without nothrow.

* This should fix all occurrences except for those in the drawing
sub directory.
* In some cases, the use of new without nothrow was okay, though.

Fix #10045.

- app_server's FontManager also needs to watch ~/config/non-packaged/fonts.

Remove B_COMMON*_DIRECTORY and kCommon*Directory constants

* This does intentionally break source compatibility, so that a review
of concerned code is forced.
* Binary compatibility should be maintained in most cases. The values
of the constants for the writable directories are now used for the
writable system directories. The values for the non-writable
directories are mapped to "/boot/system/data/empty/...", an empty or
non-existent directory, so that they will simply be skipped in search
paths. Only code that explicitly expects to find something in a
B_COMMON_* directory, will fail.

FontManager: fixed trace mode

Get app_server working on x86_64.

With this commit, app_server now compiles and runs at boot! Nothing
particularly interesting happens, just the blue background and a mouse
pointer. Remote backends are broken and not compiled in, see #8834.
Note that it won't be possible to build this quite yet, need to get
the FreeType package uploaded.

Cleanup app server directory a bit by creating a font and a decorator sub folder.
