ltlparse, eltlparse: avoid unnecessary calls to strlen().

Browse source 
* src/ltlparse/ltlscan.ll, src/ltlparse/parsedecl.hh (flex_set_buffer):
Take a std::string as argument and call yy_scan_bytes() with
the string size() instead of calling yy_scan_string() which does
strlen() on the supplied string.
* src/ltlparse/ltlparse.yy: Adjust calls.
* src/eltlparse/eltlscan.ll, src/eltlparse/parsedecl.hh,
src/eltlparse/eltlparse.yy: Use a similar interface.  This
also fixes a memory leak as the scanned buffer was not
released.
