Replace direct accesses to sched_active_thread and sched_active_pid with
the helper functions thread_getpid() and thread_get_active(). This serves
two purposes:
1. It makes accidental writes to those variable from outside core less likely.
2. Casting off the volatile qualifier is now well contained to those two
functions
gnrc_sixlowpan_frag_rm_by_datagram() currently doesn't release the
packet in the reassembly buffer entry removed, meaning it puts a leak
into the packet buffer. This changes the tests to check for that error.
- Define test_utils_interactive_sync as DEFAULT_MODULE in Makefile.tests_common
- For tests disabling autoinit, add test_utils_interactive_sync to main
- Add DISABLE_MODULE += test_utils_interactive_sync for tests requiring
sudo, `tests/shell`, `tests/minimal` and `tests/stdin`
- Add shell_commands to tests/periph_wdt and tests/struct_tm_utility to
pull `r` and `s` commands
- Remove includes and usage in `tests/main.c` for tests that where
already using test_utils_interactive_sync
Rather than dispatching the packet automatically once it is complete,
`gnrc_sixlowpan_frag_rb_add()` now only returns success, and leaves it
to the caller to dispatch the packet.
While looking at tests/gnrc_ipv6_ext_frag again while writing
RIOT-OS/Release-Specs#137, I noticed that several of tests that I
definitely wrote myself from scretch are attributed wrong (and
sometimes even documented wrong). I guess this was caused by just
copy-pasting the files...
