I forgot to put ASN1_CHOICE_END_cb in the StatementMacros list, which
caused it to mangle the formatting a bit. Also remove the duplicate
ASN1_SEQUENCE_END.

Types which do not contain an X509_NAME can be const. X509_NAME still
requires some thought. (i2d_X509_NAME can mutate the object and isn't
even thread-safe when modified.)

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.

See also 006906cddda37e24a66443199444ef4476697477 from OpenSSL, though
this CL uses a different strategy from upstream. Upstream makes
ASN1_item_ex_i2d continue to allow optionals and checks afterwards at
every non-optional call site. This CL pushes down an optional parameter
and says functions cannot omit items unless explicitly allowed.
I think this is a better default, though it is a larger change. Fields
are only optional when they come from an ASN1_TEMPLATE with the OPTIONAL
flag. Upstream's strategy misses top-level calls.
This CL additionally adds checks for optional ASN1_TEMPLATEs in contexts
where it doesn't make sense. Only fields of SEQUENCEs and SETs may be
OPTIONAL, but the ASN1_ITEM/ASN1_TEMPLATE split doesn't quite match
ASN.1 itself. ASN1_TEMPLATE is additionally responsible for
explicit/implicit tagging, and SEQUENCE/SET OF. That means CHOICE arms
and the occasional top-level type (ASN1_ITEM_TEMPLATE) use ASN1_TEMPLATE
but will get confused if marked optional.
As part of this, i2d_FOO(NULL) now returns -1 rather than "successfully"
writing 0 bytes. If we want to allow NULL at the top-level, that's not
too hard to arrange, but our CBB-based i2d functions do not.
Update-Note: Structures with missing mandatory fields can no longer be
encoded. Note that, apart from the cases already handled by preceding
CLs, tasn_new.c will fill in non-NULL empty objects everywhere. The main
downstream impact I've seen of this particular change is in combination
with other bugs. Consider a caller that does:
GENERAL_NAME *name = GENERAL_NAME_new();
name->type = GEN_DNS;
name->d.dNSName = DoSomethingComplicated(...);
Suppose DoSomethingComplicated() was actually fallible and returned
NULL, but the caller forgot to check. They'd now construct a
GENERAL_NAME with a missing field. Previously, this would silently
serialize some garbage (omitted field) or empty string. Now we fail to
encode, but the true error was the uncaught DoSomethingComplicated()
failure. (Which likely was itself a bug.)

Some of the X509 functions are hard to document without first
documenting the ASN.1 types themselves. (ASN1_TYPE's goofy
representation is leaked everywhere.)

If clang-format sees STACK_OF(T) *foo, it has a hard time telling
whether * is a multiplication or a pointer and often indents things
wrong. There is now a TypenameMacros option to fix this.

clang-format now reorders includes. It used to simply sort within
blocks, but later it added a "regroup" option. The regroup option is a
bit aggressive and does not take into account our project headers being
referenced in <system/header.h> style. (It also won't be able to
recognize the header corresponding to the source file, but perhaps we
should drop that rule.)
For now, just revert it to Preserve.
