Description:
------------
html_parse not works due to the failure of hash_create() and 
hash_destroy(). The problem may be that on mac osx, php5.3.2 
links certain lib which has the symbols with name 
hash_create()/hash_destroy(). I changed hash_create() and 
hash_destroy() to hash_create2() and hash_destroy2() in 
src/ekhtml.c,src/hash.c,src/hash.h, then it works.

Reproduce code:
---------------
function f_data($text) {
   echo "Data: '$text'\n";
}
$parser = html_parser_create();
html_parser_data_handler($parser, "f_data");
html_parser_parse($parser, "foo <x name='hello' id=23> <!-- <x></x> -->bar </x> baz");
html_parser_free($parser);

Expected result:
----------------
Data: 'foo '
Data: ' '
Data: 'bar '
Data: ' baz'

Actual result:
--------------
Program received signal EXC_BAD_ACCESS, Could not access 
memory.

Apparently, PECL/html_parse is unmaintained, so I'm suspending
this ticket.
