Simulator: Adds necessary functionality to build Simulator under ARM Linux. Tested only on Raspberry3. Currently setjmp/longjmp do not save/restore floating point registers.  Patch provided by Bitbucket user nbkolchin.

6LoWPAN:  The original, Contiki-based design used only a single buffer for reassemblying larger packets.  This could be a problem issue for hub configurations which really need the capability concurrently reassemble multiple incoming streams concurrently.  These was also a design issue in that the reassembly buffer could be corrupted by outgoing packets.  The design was extended to support multiple reassembly buffers, each associated with the reassembly tag and source address.  This assures that there can be be no corruption of the reassembly once it has started.

STM32L4 DAC: report transfer as completed in DMA callback.  Without this even O_NONBLOCK writes block the calling task if DAC was using DMA.

drivers/audio:  Fix naming of configurations to be compliant for vs1053 audio driver.  One file was not saved before last commit.

drivers/sensors:  Fix more naming of configurations to be compliant for two more drivers.  Still a few more to go.

drivers/sensors:  Fix more naming of configurations to be compliant for two more drivers.  Still a few more to go.

drivrs/sensors:  Make a few other configuration settings consistent with the (undocumented) standard.

drivrs/sensors/hts221:  Fix inconsistent configuration variable naming; Try to bring closer to an as-of-yet undocumented naming convention.

drivers/wireless/spirit: Fixes a pre-processor directive

Network procfs: procfs/net_procfs_route.c building error occur if CONFIG_NET_ROUTE is enabled.  Fix suggested by Aleksandr Kazantsev

drivers/lcd: ssd1306: separate lcd_dev_s setup to separate object.  g_oleddev takes 1 KiB because framebuffer and was allocated to .data section because of lcd_dev_s function pointer setup. Move lcd_dev_s setup out, so that g_oleddev goes to .bss and avoid wasting ROM.

drivers/lcd: ssd1306: fix memory corruption caused by ssd1306_getrun().  ssd1306_getrun was writing one extra byte (with value 0) past target buffer when pixlen is multiple of 8. When pixlen was not multiple of 8, last byte of buffer was fully cleared, instead of modifying only the (pixlen % 8) bits of last byte.

drivers/lcd: ssd1306: add support for board power control.  ThingseeOne has regulator for controlling display power on/off.  Patch adds support for board based power control to SSD1306 driver.
