- move req_ctx_find_get into ram, since this is frequently used within
interrupt handlers and thus ought to be as fast as possible
- correctly initialize req_ctx size (bugfix!)

- Build UTF-16LE USB String descriptors from ASCII File
- Introduce USB String Descriptor to DFU and runtime firmware

- add more fine-grained debugging macros in pcd_enumarate.c
- resolve race conditions between main-loop ep_refill and irq-triggered
ep_refill by adding one irq-[b]locking variant
- consolidate endpoint reset code into reset_ep()
- add code to handle correct transmission and reception of usb transfers
larger than endpoint size
- use new jump address (0x104000) in DFU Cstartup.S
- move main_usb to pcd subdirectory
- fix include/compile.h make dependencies
- make usb benchmark code use new large req_ctx

all the req_ctx state changes from within pcd_handler.c and only expose the
refill_ep() functions.
It's questionable whether we need to keep calling those functions all the time
either. Once kicked off, the tx completion interrupts of the UDC will refill
the pipe as long as there is data available.
So realistically speaking, we'd only need to trigger tx once (and keep
triggering until no EBUSY or other error is signalled anymore). Some form of
state machine would be fine for doing this, one that registers a timer with
the core OS timer (once we have something equivalent to 'struct timer_list'.

- Add automatic generation of include/compile.h with svn revision and compiletime
- Add openpcd_compile_version structure to obtain version via USB
- Move LED commands into new CMD_CLS_GENERIC family
- Update TODO
- Add support for large (2048 byte) request contexts in addition to 64byte
- Shrink req_ctx size by collapsing rx and tx buffer into one
- move definition of DFU_API_LOCATION to header file
- Implement large req_ctx aware USB transmit / refill routines
- Implement TX refilling for IRQ Endpoint
- Print version information at startup time
- move some generic req_ctx processing into usb_handler.c
- Some further work on DFU (still not finished)
- Only use '-Os' for DFU, use '-O2' for application code

DFU occupies 0x00100000 - 0x00100fff in flash, application starts at 0x00101000.
DFU also occupies the first couple of bytes in SRAM, application starts at 0x00200024.
In order to produce a samba-flashable image, first build dfu.bin by typing
'make -f Makefule.dfu', succeeded by 'make TARGET=... DEBUG=... BOARD=...' and then
concatenating the two files together, e.g. cat dfu.bin main_reqa.bin > flash.bin.
Actual flashing via DFU is still not operational, but will be implemented next
