* 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.
