This patch removes the string length limit in convert_aaregex_to_pcre()
usage. One of the benefits to moving to C++ is the ability to use
std::strings, which dynamically resize themselves. While it's a large
patch, a non-trivial amount is due to needing to get a char * string
back out via the c_str() method.
The unit tests are modified to include checks to ensure that
convert_aaregex_to_pcre only appends to the passed pcre string,
it never resets it.
As the test case with overlong alternations added in the previous
patch now passes, the TODO status is removed from it.
(Note: there's a couple of FIXME comments related to converting typebuf
to std::string that are added by this patch that are addressed in the
next patch. I kept that conversion separate to try to reduce the size
of this patch a little.)
