XMLIMPORT - Whatever magic is needed to note that a function is
to be imported from a dynamically loaded library
(.dll, .so, or .sl, depending on your platform).
The XMLCALL macro was added in Expat 1.95.7. The only one which is
expected to be directly useful in client code is XMLCALL.

Internal definitions used by Expat. This is not needed to compile

The following calling convention macros are defined for frequently
called functions:
FASTCALL - Used for those internal functions that have a simple
body and a low number of arguments and local variables.
PTRCALL - Used for functions called though function pointers.
PTRFASTCALL - Like PTRCALL, but for low number of arguments.
inline - Used for selected internal functions for which inlining
may improve performance on some platforms.

If this is your first time building the HTML5 parser, you need to execute the
following commands (from this directory) to bootstrap the translation:
make sync # fetch remote source files and licenses
make translate # perform the Java-to-C++ translation from the remote
# sources
make named_characters # Generate tables for named character tokenization
If you make changes to the translator or the javaparser, you can rebuild by
retyping 'make' in this directory. If you make changes to the HTML5 Java
implementation, you can retranslate the Java sources from the htmlparser
repository by retyping 'make translate' in this directory.
The makefile supports the following targets:
sync_htmlparser:
Retrieves the HTML parser and Java to C++ translator sources from Mozilla's
htmlparser repository.
sync_javaparser:
Retrieves the javaparser sources from GitHub.
sync:
Runs both sync_javaparser and sync_htmlparser.
javaparser:
Builds the javaparser library retrieved earlier by sync_javaparser.
translator:
Runs the javaparser target and then builds the Java to C++ translator from
sources retrieved earlier by sync_htmlparser.
libs:
The default target. Alias for translator
translate:
Runs the translator target and then translates the HTML parser sources
retrieved by sync_htmlparser copying the Java sources to ../javasrc.
translate_from_snapshot:
Runs the translator target and then translates the HTML parser sources
stored in ../javasrc.
named_characters:
Generates data tables for named character tokenization.
clean_javaparser:
Removes the build products of the javaparser target.
clean_htmlparser:
Removes the build products of the translator target.
clean:
Runs both clean_javaparser and clean_htmlparser.

/**
* nsHtml5AtomTable provides non-locking lookup and creation of atoms for
* nsHtml5Parser or nsHtml5StreamParser.
*
* The hashtable holds dynamically allocated atoms that are private to an
* instance of nsHtml5Parser or nsHtml5StreamParser. (Static atoms are used on
* interned nsHtml5ElementNames and interned nsHtml5AttributeNames. Also, when
* the doctype name is 'html', that identifier needs to be represented as a
* static atom.)
*
* Each instance of nsHtml5Parser has a single instance of nsHtml5AtomTable,
* and each instance of nsHtml5StreamParser has a single instance of
* nsHtml5AtomTable. Dynamic atoms obtained from an nsHtml5AtomTable are valid
* for == comparison with each other or with atoms declared in nsHtml5Atoms
* within the nsHtml5Tokenizer and the nsHtml5TreeBuilder instances owned by
* the same nsHtml5Parser/nsHtml5StreamParser instance that owns the
* nsHtml5AtomTable instance.
*
* Dynamic atoms (atoms whose IsStaticAtom() returns false) obtained from
* nsHtml5AtomTable must be re-obtained from another atom table when there's a
* need to migrate atoms from an nsHtml5Parser to its nsHtml5StreamParser
* (re-obtain from the other nsHtml5AtomTable), from an nsHtml5Parser to its
* owner nsHtml5Parser (re-obtain from the other nsHtml5AtomTable) or from the
* parser to the DOM (re-obtain from the application-wide atom table). To
* re-obtain an atom from another atom table, obtain a string from the atom
* using ToString(nsAString&) and look up an atom in the other table using that
* string.
*
* An instance of nsHtml5AtomTable that belongs to an nsHtml5Parser is only
* accessed from the main thread. An instance of nsHtml5AtomTable that belongs
* to an nsHtml5StreamParser is accessed both from the main thread and from the
* thread that executes the runnables of the nsHtml5StreamParser instance.
* However, the threads never access the nsHtml5AtomTable instance concurrently
* in the nsHtml5StreamParser case.
*
* Methods on the atoms obtained from nsHtml5AtomTable may be called on any
* thread, although they only need to be called on the main thread or on the
* thread working for the nsHtml5StreamParser when nsHtml5AtomTable belongs to
* an nsHtml5StreamParser.
*
* Dynamic atoms obtained from nsHtml5AtomTable are deleted when the
* nsHtml5AtomTable itself is destructed, which happens when the owner
* nsHtml5Parser or nsHtml5StreamParser is destructed.
