This enables 'pthread' support on arduino.
avr-libc C90 'time.h' does not include 'sys/types.h' as POSIX expects it.
However, the type previously defined conflicts with the one in
'cpu/atmega_common/avr_libc_extra/include/sys/types.h' when both are
included, so include 'sys/types.h'.
Maybe it should alway be included by 'time.h' but this
would need its specific review.
Missing malloc.h and clock_id_t were causing issues to build.
It was tested with this configuration:
- linux ubuntu 14.04.5
- arduino-mega2560 board
- avr-libc-1.8.0-4.1
This change was needed to build iotivity example

The pthread header files aren't in the doxygen page anymore after #1137,
because I `@file`'d the `.c` files, not the `.h` files.
This change moves doxygen boilerplate.
Closes#1199.
