<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Well, if chunk_length is *really* big, even bufsize *=2 might not be sufficient.
In fact, MAX_POST_CONTENT is 1025, so we should never actually hit this code, since we explicitly disallow a chunk_length + content_length greater than that.</pre>

Relocated code from ast_http_get_json() and ast_http_get_post_vars() that reads content from stream into new function ast_http_get_contents(), and added support for reading and decoding chunked mode transfers.</pre>
