Now we have a list of all commands. This is a good thing in itself, but it
also enables us to easily implement typo correction for command names.
With this change we have objects that contain information about each command,
so it makes sense to resolve command name just once during lexing (currently we
store command names as strings and do a linear search every time some property
value is needed). Thus comment token and AST nodes were changed to contain a
command ID -- index into a tables of builtin and registered commands. Unknown
commands are registered during parsing and thus are also uniformly assigned an
ID. Using an ID instead of a StringRef is also a nice memory optimization
since ID is a small integer that fits into a common bitfield in Comment class.
This change implies that to get any information about a command (even a command
name) we need a CommandTraits object to resolve the command ID to CommandInfo*.
Currently a fresh temporary CommandTraits object is created whenever it is
needed since it does not have any state. But with this change it has state --
new commands can be registered, so a CommandTraits object was added to
ASTContext.
Also, in libclang CXComment has to be expanded to include a CXTranslationUnit
so that all functions working on comment AST nodes can get a CommandTraits
object. This breaks binary compatibility of CXComment APIs.
Now clang_FullComment_getAsXML(CXTranslationUnit TU, CXComment CXC) doesn't
need TU parameter anymore, so it was removed. This is a source-incompatible
change for this C API.

The implementation also includes a Relax NG schema and tests for the schema
itself. The schema is used in c-index-test to verify that XML documents we
produce are valid. In order to do the validation, we add an optional libxml2
dependency for c-index-test.
Credits for CMake part go to Doug Gregor. Credits for Autoconf part go to Eric
Christopher. Thanks!

The only caveat is renumbering CXCommentKind enum for aesthetic reasons -- this
breaks libclang binary compatibility, but should not be a problem since API is
so new.
This also fixes PR13372 as a side-effect.

by index. This is useful if the user does not document all arguments, and we
can't find a particular argument by index via :nth-of-type() CSS selector.

HTML fragment.
For testing, c-index-test now has even more output:
* HTML rendering of a comment
* comment AST tree dump in S-expressions like Comment::dump(), but implemented
* with libclang APIs.
