Introduce the subset of svn_cstring_ functions into APR as the apr_cstr_

family of functions.  Requires the introduction of APR_ERANGE.
Solves apr_cstr_casecmp[n] for ASCII and EBCDIC and borrows
from the work of jim, ylavic and wrowe, see r1715401 forwards in;
  http://svn.apache.org/viewvc/httpd/httpd/trunk/server/util.c?view=log&pathrev=1722194
More performance review is needed against different compilers, so went ahead
and borrowed original svn implementation as a basis, and we can port whichever
performance enhancements test out more efficiently.

Proposing for APR 1.6.0 which is the thought behind the initial @since tags.
These must be changed if not accepted for backport.

Note that the svn_cstring_join function could not be implemented as-is
due to the absence of svn's counted string functionality.  It deserves
an implementation if not already present, or should be removed before
tagging or backporting.

No whitespace/formatting cleanup on this pass in order to preserve as
much of the svn attributions as possible.  This can happen in a later
pass to conform to APR's style conventions.  While renaming the functions,
declarations themsel
