(This is a merge of http://go/wvgerrit/13761 from the Widevine repository.) This cleans up our includes to be in Google Style Guide order and in alphabetic order, for the parts of the code that are expected to follow Google Style. This also converts places in our code that were including C headers in the C++ style (i.e. <cstring> instead of <string.h>) to use C style instead. This is because, although it was not causing problems for us yet, on Android these actually include different headers. (<cstring> is provided by libcxx, while <string.h> is provided by Bionic) Lastly, this change puts all headers that do not come from within our project in <brackets> instead of "quotes," which was not being done consistently. This change is explicitly NOT trying to standardize the spacing of our header includes. I have tried to respect, in each file, the spacing style already present.
