Add compile assertions to enforce the sizes of all structs and enums in the C API. Adjust some structs to make their sizes consistent across architectures. Note that some structs contain pointers, so are difficult to make consistent between 32-bit and 64-bit. Those types are in test_struct_sizes.c. Other types have a compile assertion immediately after their definition.
This was broken off from a bigger CL:
http://codereview.chromium.org/5340003/
BUG=61004,92983
TEST=test_struct_sizes.c, compile assertions throughout
See this CL for the code that helped generate the static assertions and find affected interfaces:
