Support disabling feedback format correction #1234

When dcd_edpt_xfer() starts new transfer two separate problems were observed.
For both problems stream of OUT packets was pouring from host.
First problem was that total_len and actual_len were not atomic.
In case where incoming OUT packets are less (63) than MPS (64), actual_len and total_len
are set 63.
Then transfer complete from USBD is called that will schedule next 64 bytes transfer.
At that point incoming packet would start DMA if there is place in RAM, normally
it does not happen since actual_len == total_len.
If packets arrives and interrupt is raised after total_len is set (64) but actual_len is still 63 from
previous transfer, interrupt code sees that there is place in ram (1 byte) and transfer this 1 byte
to buffer that was already filled with previous packet.
To remedy this USB interrupt is blocked during transfer setup.
Second problem can happen when dcd_edpt_xfer setups xfer->total_len and actual_len correctly
but then context switch happens before xfer->data_received is checked.
If during this time two packets arrive one will be copied to RAM second will stay in endpoint with
data_received set to 1.
Then when xfer_edpt_xfer() checks data_receive flag it starts DMA again overwriting data.
To remedy this, data_received is checked together with check if data was already transferred.
If transfer was complete, there is no need to start DMA yet.
In such case data_received will be handled in same place by next xfer_edpt_xfer() correctly.

dwMaxFrameInterval minus dwMinFrameInterval should be evenly divisible by
dwFrameIntervalStep.

Two boards from Olimex are added:
olimex_hmz144 with PIC32MZ2048EFM144
olimex_emz64.c with PIC32MZ2048EFH064
Both can be programmed with Segger JLINK probe using ICSP
interface. (JTAG not tested but could also work but header
is not mounted).

These are different Broadcom chips. The peripherals are essentially
the same. The main differences are:
* The CPU(s)
* The interrupt controller
* The peripheral base address (but not the peripherals that we use)

definition of DEBUG breaks Microchip pic32 builds for Mynewt.
When MCU is not VALENTYUSB_EPTRI there is no need to have any
preprocessor definitions.
It may not look like a big deal but for xc32 builds, compiler
automatically force-includes some file that have structure with field name
DEBUG that result in build error in dcd_eptri.c when this file
is not really needed.
Moving DEBUG and LOG_USB few lines down should not break eptri builds.

Three changes are needed to accommodate xc32 compiler build:
- optimized build flag other than -Os
added CFLAGS_OPTIMIZED that defaults to -Os but can be overridden in boards
- build without -lnosys
added LIBS_GCC with default libraries that can be changed in boards
- build without LD_FILE specification
if LD_FILE is empty -Wl,-T options is not added to LDFLAGS
