Update flex to 2.6.0.

While here, send patches upstream.

Changes:
* version 2.6.0 released 2015-11-17

** User Visible Changes

*** C++ scanners now use references instead of pointers. See the manual for details.

*** A number of compiler warnings were addressed, so flex generated scanners should be quieter under compiler warning scenarios.

*** Allow error reporting routines to accept varying number of arguments

*** Removed deprecated 'register' storage class specifier

*** Changeed output formats from octal to hexadecimal

*** check limits before using array index cclp; resolves sf-166

*** Suppress clang warning about empty @param paragraph; resolves sf#158

*** Fixed malloc/realloc replacement, resolves sf bug#151.

*** Adjusted buffer sizes on ia64.

*** various documentation and code clean up fixes: resolves sf bugs #167, #168, among other patches.

** Flex Internals

*** flex is now organized into subdirectories. This keeps the tree neater at the top level and puts like things near each other and unlike things away from each other.

*** The test suite has been reorganized and is now run with the parallel test suite harness from automake.

*** Cleaned up the automake parts of the build system to better reflect what automake does on its own. Also added a call to libtoolize in autogen.sh because autoreconf gets confused without a prior run of libtoolize.

*** po/Makefile now includes a rule to fetch the latest translations from the translation project. "make -f po/Makefile getpo" from the top level of the flex tree will fetch the files.

*** New da translation from the translation project
