Should Use xfree Not free

In thin.c:

void Thin_HttpParser_free(void *data) {
TRACE();

if(data) {

free(data);

} }

Use of free causes heap debug failures with instrumented VC builds. The problem is that memory must be allocated and deallocated using the same runtime library.

Thin asks Ruby to allocate the memory (line 233):

http_parser *hp = ALLOC_N(http_parser, 1);

Therefore thin should ask Ruby to deallocate the memory by using the xfree method the Ruby api provides.
