This is good practice and helps to catch bugs. Several changes
were made to accomodate the newly enabled warnings:
* -Wunused-function:
* in exposed/, static functions that were supposed to be inlined
were explicitly marked as inline;
* some actually unused functions were removed;
* -Wsign-compare: explicit conversions were added, and in
the future we should find a nicer way than aux* fields;
* -Wmissing-field-initializers: added initializers;
* -Wreorder: reordered properly;
* -Wunused-but-set-variable: remove variable.
-Wunused-parameter was turned off as enabling it would result in
massive amount of churn in UI code. Despite that, we should enable
it at some point as it has a fairly high SNR otherwise.
