-Wall -Wextra and -Wno-unused in common.gypi. This revealed a lot of warnings
(and some actual bugs), all of which I fixed here. This is pretty mindless
stuff for the most part (order of intialization, missing initializers, && within
||, etc), but will allow us to build cleanly with -Wall and -Wextra (and
-Werror, if we so choose).
I put defaults into switches that were missing cases. I could put in the actual
missing enums instead if that's desired. I could also assert on missing enums
instead of break, if that's desired. I wasn't sure how to test the stuff in
"animator", so that should be looked at a bit more closely.

SkSafeRef() and SkSafeUnref().
This is basically a bug waiting to happen. An optimizing compiler can remove
checks for null on "this" if it chooses. However, SkRefCnt::safeRef() relies on
precisely this check...
void SkRefCnt::safeRef() {
if (this) {
this->ref();
}
}
Since a compiler might skip the if-clause, it breaks the intention of this
method, hence its removal.
static inline void SkSafeRef(SkRefCnt* obj) {
if (obj) {
obj->ref();
}
}
This form is not ignored by an optimizing compile, so we use it instead.

pattern: the receiver will call ref() if it chooses when passed to a constructor
or setter, so the caller must balance its ownership itself. This matches how all
other refcnt objects are handled.
