Adding the ending macros to StatementMacros tells clang-format the macro
terminates a statement. Adding trailing commas in the middle keeps it
from trying to bundle the curly brace with the next statement.
Also add a few other trailing commas that clang-format otherwise indents
awkwardly.

While C allows function pointer casts, it is UB to call a function with
a different type than its actual type signature. That is, even though
`void f(int *)` and `void g(void *)` have the same ABI, it is UB to
cast `f` to a `void(*)(void *)` and then call it through that pointer.
Clang CFI will try to enforce this rule.
The recent CL to call X509_print in tests revealed that all the i2? and
?2i callbacks in X509V3_EXT_METHODs were implemented with functions of
the wrong type, out of some combination of missing consts and void*
turned into T*.
This CL fixes this. Where the function wasn't exported, or had no
callers, I just fixed the function itself. Where it had extension
callers, I added a wrapper function with a void* type.
I'm not positive whether the wrappers are the right call. On the one
hand, keeping the exported functions as-is is more type-safe and more
OpenSSL-compatible. However, most (but not all) uses of these are in
other code defining X509V3_EXT_METHODs themselves, so the void*
signature is more correct for them too. And the functions have a type
signature meant for X509V3_EXT_METHOD, complete with method pointer.
I've gone with leaving the exported ones as-is for now. Probably the
right answer anyway is to migrate the external callers, of either type
signature.
