mod_proxy_ajp: Forward SSL protocol name (SSLv3, TLSv1.1 etc.) as a
request attribute to the backend. The name is taken from
the SSL_PROTOCOL env var. Recent Tomcat versions will extract
it and provide it as a servlet request attribute named
"org.apache.tomcat.util.net.secure_protocol_version". 

The change is compatible with existing AJP13, because we forward
the protocol name as a normal named attribute, not with a new
byte abbreviated attribute name.

core: Optimize string concatenation in expression
parser when evaluating a string expression.

We have a relatively small recursion limit of
about 10 operations. This is a compilation
limit (a define). It can be hit if many expr
vars or function calls are concatenated in an
expression that is evaluated as a string not as
a boolean.

The new optimization uses iteration instead of
recursion and is very similar to the
existing one, which optimizes consecutive
concatenations in node2 of the tree. The new
one optimizes consecutive concatenations in
node 1.
