Refactor MIME DB access

* Add class DatabaseLocation. It contains a list of the MIME DB
directory paths plus methods to access type files.
* Move all low-level MIME DB access functions from
database_{support,access} to DatabaseLocation. All code that formerly
used those now requires a DatabaseLocation object. In BMimeType and in
the registrar the default object is used, but the low-level classes
can now be reused with different locations.
* Move get_icon_data() from database_access to database_support and
delete the former, which is now empty.

Move MIME DB code back from registrar to src/kits/storage/mime

* Together with database_{access,support}.cpp it is built into a static
library.
* Add new interfaces MimeSniffer and Database::NotificationListener for
plugging in registrar specific functionality (the sniffer add-on
support and the notification mechanism).

bonefish+mmlr:
* Move most of MIME database support out of libbe and into registrar
* Use the (async) MessageDeliverer instead of a synchronous SendMessage in _SendMonitorUpdate

This fixes a deadlock when the message port of a MIME database watching
application gets full as documented in bug #1311.

* Rewrote BeBuild.h which had "a few" consequences (got rid of all those class
definitions).
* Minor cleanup here and there.

* Added new (currently private) API class BMimeSnifferAddon,
representing the interface for, well, MIME sniffer add-ons.
* Implemented the respective add-on manager and make use of it in
the MIME database code. Unfortunately the MIME DB code completely
lives in libbe.so and hence I had to put my code there too.
IMHO we should (one day) remove the direct (read-only) MIME DB
access from libbe and move everything into the registrar.
Currently the add-on manager supports built-in add-ons only; it
doesn't really load anything from disk ATM.
* Added a built-in text sniffer add-on to the registrar. It's based
upon the BSD file tool code.

This closes bug #250 (plain text files are identified as such, now).

responsible for managing sniffer rules and sniffing files and data
streams.
