pio.c - remove redundant include (lualib.h includes lua.h)
STM32F4 - uip-conf.h - replace with identical file with less restrictive copyright
uip-conf.h (various platforms) - note inconsistency -
comment says UIP_CONF_UDP_CHECKSUMS should be 0, but it is 1
so which is right?  (comment or code)
LM3S - ethernet - make platform net functions use their arguments
rather than assuming they are dealing with uip_buf
LM3S - ek-lm3s6965.lua - fix cpu, was lm3s8962 rather than lm3s6965
missing return on stm32[f4] enc handler set functions
prevent calling tmr_int_handler with negative numbers since id indexes into an array
Make sure we actually get a file descriptor before creating new WOFS file
remove unused variable from bit library
check that INT_TMR_MATCH is not set to invalid interrupt
remove unnecessary signed comparisons with unsigned type
handle zero element size for bitarray
STM32 - #elseif -> #elif
STM32F4 - TCK/SWDCLK should be pulled down, not up.
Merge pull request #51 from smartavionics/mb-stm32f4-tck-pulldown

STM32F4 - TCK/SWDCLK should be pulled down, not up.
enable cdc on mizar32a, b and soldercore (had uart=cdc, but cdc not built)
Merge pull request #50 from ecdr/MiscUpdates

LM3S - correct cpu in ek-lm3s6965 board file, ethernet functions, enable cdc in board files
