First changes for adding functionality to write binary output and write to a mysql database.
Fixed some merges
Changes to make compilation with db separate.  You can specify --enable-byfl-db and --with-mysqlcppconn-libdir and --withmysqlcppconn-includedir so that it compiles with the database output capability and also builds the bf2mysql postprocessing tool.
Removed some old comments.
Added byfl-db-stubs.cpp and small change in byfl.cpp.
Changes for compilation and some bug fixes.
Merge branch 'master' of https://github.com/losalamos/Byfl
Made changes to autoconf for byfl db.  Will add even more later, but this is the basics.
Updated to build with LLVM 3.5
Merge branch 'database'

The purpose of this merge is to preserve the contents of the
"database" branch, which represents Christine Sweeney's (@cmahrens)
version of the code, which writes counter data to a MySQL database and
to a raw binary file.

The database branch has been superseded by Byfl's new, self-describing
binary output format and postprocessor that converts from that format
to the SQLite3 database format.  However, it may be useful to keep a
record of Christine's earlier attempt to make Byfl more
database-friendly; hence, this merge.
