Remove some instances where a RewriteBase must be specified

Previously, any time you used a relative substitution in 
per-directory/htaccess context, you needed to specify
a RewriteBase. But in case where the context document root 
and context prefix are known via e.g. mod_userdir
or mod_alias, and the substitution is under the context 
document root, we can determine the replacement automatically.

This makes htaccess files or config snippets a bit more
portable.

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.

Using session tickets without restarting the web server with

there needs to be a way to deactivate the use of session tickets.
