Jim Derry 51e2e0f3bd Following the example of the recent changes in the "reports" aspect of Tidy's
output, classify and organize all of the dialogue type of messages. This paves
the way towards formalizing (and expanding!) the footnotes system with much
greater explanatory text, as well as providing much better fine-grained control
over which types of output that Tidy will produce.

Moved STRING_DOCTYPE_GIVEN, STRING_CONTENT_LOOKS, and STRING_NO_SYSID to the
Report paradigm from the Dialogue paradigm, as these are items that are
traditionally TidyInfo and included in the Report table, rather than any type
of dialogue.

At this point, we are exactly passing all tests.

* Defines HTML Tidy public API implemented by LibTidy.
*
* This public interface provides the entire public API for LibTidy, and
* is the sole interface that you should use when implementing LibTidy in
* your own applications.
*
* See tidy.c as an example application implementing the public API.
*
* This API is const-correct and doesn't explicitly depend on any globals.
* Thus, thread-safety may be introduced without changing the interface.
*
* The API limits all exposure to internal structures and provides only
* accessors that return simple types such as C strings and integers, which
* makes it quite suitable for integration with any number of other languages.

/* MARK: - Memory Allocation */
/***************************************************************************//**
** @defgroup Memory Memory Allocation
**
** Tidy can use a user-provided allocator for all memory allocations. If this
** allocator is not provided, then a default allocator is used which simply
** wraps standard C malloc()/free() calls. These wrappers call the panic()
** function upon any failure. The default panic function prints an out of
** memory message to **stderr**, and calls `exit(2)`.
**
** For applications in which it is unacceptable to abort in the case of memory
** allocation, then the panic function can be replaced with one which
** `longjmps()` out of the LibTidy code. For this to clean up completely, you
** should be careful not to use any Tidy methods that open files as these will
** not be closed before `panic()` is called.
**
** Calling the `xxxWithAllocator()` family (`tidyCreateWithAllocator`,
** `tidyBufInitWithAllocator`, `tidyBufAllocWithAllocator`) allow setting
** custom allocators.
**
** All parts of the document use the same allocator. Calls that require a
** user-provided buffer can optionally use a different allocator.
**
** For reference in designing a plug-in allocator, most allocations made by
** LibTidy are less than 100 bytes, corresponding to attribute names and
** values, etc.
**
** There is also an additional class of much larger allocations which are where
** most of the data from the lexer is stored. It is not currently possible to
** use a separate allocator for the lexer; this would be a useful extension.
**
** In general, approximately 1/3rd of the memory used by LibTidy is freed
** during the parse, so if memory usage is an issue then an allocator that can
** reuse this memory is a good idea.
**
** **To create your own allocator, do something like the following:**
** @code{.c}
** typedef struct _MyAllocator {
** TidyAllocator base;
** // ...other custom allocator state...
** } MyAllocator;
**
** void* MyAllocator_alloc(TidyAllocator *base, void *block, size_t nBytes) {
** MyAllocator *self = (MyAllocator*)base;
** // ...
** }
** // etc.
**
** static const TidyAllocatorVtbl MyAllocatorVtbl = {
** MyAllocator_alloc,
** MyAllocator_realloc,
** MyAllocator_free,
** MyAllocator_panic
** };
**
** myAllocator allocator;
** TidyDoc doc;
**
** allocator.base.vtbl = &MyAllocatorVtbl;
** //...initialise allocator specific state...
** doc = tidyCreateWithAllocator(&allocator);
** @endcode
**
** Although this looks slightly long-winded, the advantage is that to create a
** custom allocator you simply need to set the vtbl pointer correctly. The vtbl
** itself can reside in static/global data, and hence does not need to be
** initialised each time an allocator is created, and furthermore the memory
** is shared amongst all created allocators.
