Merge r1435178 from trunk:
mod_proxy_ajp: Support unknown HTTP methods.
BZ 54416
Forward unknown methods as request attributes
using method id SC_M_JK_STORED=0xFF and
request attribute id SC_A_STORED_METHOD=13.
Code ported from mod_jk (which got it from mod_jk2).
Supported by Tomcat at least since TC 4.1.
Doesn't seem to be supported by Jetty though.
