This PR converts tabs to white spaces.
The statement I used for the conversion:
```find . -name "*.[ch]" -exec zsh -c 'expand -t 4 "$0" > /tmp/e && mv /tmp/e "$0"' {} \;```
Afterwards, I had a quick overview of the converted files to prevent odd indentation.
Creates file structure that maps files to licenses by grepping for
license patterns (patterns for licenses found in RIOT included).
Sets exit code to 1 if an unknown license header is detected.
While tracking down an error in #1253 I ameded newlib a bit to be
slightly better debuggable. Some lengthy macros were removed in favor of
proper functions.
The parameter passing was wrong before (because of a bug in newlib),
because the user provided CFLAGS were overwritten in the subfolders.
It is kinda strange that this did not cause errors.
The standalone version of the toolchain script was deleted, because it
is not reasonable to maintain two scripts.
The wireshark dissector plugin currently fails with a "Lua Error" when
trying to parse nativenet packets. This patch restores working behaviour
by commenting the offending line introduced in 1258675, which intention
was to account for padding in small packets. It further adds a comment
on how to edit the plugin for the case padding information is required.
The README.md now contains a usage note for configuration on fedora
which might also be helpful for users of other distributions.
`compile_test.py` fails if there are empty folders in `/examples` or
`tests`. This is not a problem for Travis, because it always has a clean
repo.
For the average users there is a problem if they work on multiple
branches and one branch has new examples or tests. If they don't delete
the residual `bin` folders, then `compile_test.py` will print out these
applications as having failed.
This change checks for the existence of a `Makefile` in the application
folder. Also I added a progress indicator, because I like it. :)
Having many tests is quite futile if they aren't executed once in a
while<sup>[citation needed]</sup>.
Alas, this is not the purpose of this PR. This PR adds the tool
"compile_test.py", which executes `make buildtest` for all applications
in `examples` and `tests`, and prints a comprehensive list of the
results.
