Functions tidy_error_count, tidy_warning_count and tidy_get_error_buffer are inconsistent in case of multiple calls in the same process.

Reproduce code:
---------------
<?php
$file = file_get_contents("http://www.amazon.com/");
tidy_setopt("accessibility-check", 1);

for ($i=0; $i < 4; $i++) {
    tidy_parse_string($file);
    echo tidy_error_count() ."+". tidy_warning_count() ." = ". substr_count(tidy_get_error_buffer(), "\n") ."\n";
}
?>


Expected result:
----------------
5+266 = 271
5+266 = 271
5+266 = 271
5+266 = 271


Actual result:
--------------
5+266 = 271
11+265 = 10
17+265 = 0
23+265 = 0
