merge r3153, r3154, r3288, r3382:
request header processing fixes:
*) $host is always in low case:
*) move low case convertation from ngx_http_find_virtual_server()
to ngx_http_validate_host()
*) add in ngx_http_validate_host() capability to copy host name in the pool
allocated memory
*) fix segfault if there is single large_client_header_buffers
and a request line fills it completely
*) default large_client_header_buffers' buffer size should be 8K as compatible
with Apache's one
