Major layout change to the packages directory

Having one monolithic packages directory makes it hard to find things
and is generally overwhelming. This commit splits it into several
logical sections roughly based on function, recipes.txt gives more
information about the classifications used.

The opportunity is also used to switch from "packages" to "recipes"
as used in OpenEmbedded as the term "packages" can be confusing to
people and has many different meanings.

Not all recipes have been classified yet, this is just a first pass
at separating things out. Some packages are moved to meta-extras as
they're no longer actively used or maintained.

-From: Petr Vandrovec <vandrove@vc.cvut.cz>
-
-Patch below adds support for using different prescaler than 16 for 16c950
-chips.  This is needed for using Fujitsu-Siemens Connect2Air compact-flash
-card, which comes (apparently) with 806kHz clocks, and so you have to
-program prescaler for division by 7, and DLAB to 1, to get 115200Bd.  
-
-To get card properly running you also have to add lines below to
-/etc/pcmcia/serial.opts so kernel knows that base speed is not 115200 but
-50400 (50400 * 16 = 806400; 806400 / 7 = 115200).  As I've found no code
-specifying baud_rate in serial_cs, I assume that specifying it in
-serial.opts is right way to do this type of things.
-
-Patch also fixes problem that for UPF_MAGIC_MULTIPLIER maximum possible
-baud rate passed to uart code was uartclk / 16 while correct value for
-these devices (and for 16c950) is uartclk / 4.
-
-Patch also fixes problem that for UPF_MAGIC_MULTIPLIER devices with
-baud_rate 19200 or 9600 spd_cust did not work correctly.  Not that such
-devices exist, but we should not ignore spd_cust, user probably knows why
-he asked for spd_cust.
-
-serial.opts:
-
-case "$MANFID-$FUNCID-$PRODID_1-$PRODID_2-$PRODID_3-$PRODID_4" in
-'0279,950b-2-GPRS Modem---')
-    SERIAL_OPTS="baud_base 50400"
-    ;;
-esac
