Some options passed to the cam utility need to be complex and specify a
list of key=value pairs. Add a new parser to deal with these options,
usable on its own to parse key=value pairs from any string.
Integrate the KeyValueParser into the existing OptionsParser. The cam
application can fully describe all its options in one location and
perform full parsing of all arguments in one go. The KeyValueParser also
integrates itself with the usage() printing of the OptionsParser.

Extend the options parser with support for option types. All options
must now specify the type of their argument, and the parser
automatically parses the argument and handles errors internally.
Available types are none, integer or string.

To later extend the options handling to cover subparsing of arguments it
will be needed to know if the addition of the option itself was
successful or not. The information is already present in addOption()
this change just makes it available.

In preparation to adding more parsers create a template class to hold
the parsed information. The rational for making it a template are that
different parsers can index the options using different data types.
The OptionsParser index its options using an int while the upcoming
KeyValyeParser will index its options using strings for example.

It's not stated in the getopt_long documentation but optional arguments
need to be specified as '--foo=bar' instead of '--foo bar', otherwise
the value is not propagated to optarg during argument parsing. Update
the usage printing helper to reflect this requirement.

The compiler creates a move constructor automatically when none is
supplied, and it does the right thing by default in this case. Using
std::move() inside the function prevents the compiler from doing
return value optimization and actually hinders performances. Using
std::move() in the caller is unnecessary, the move constructor is used
automatically by the compiler.
For all these reasons remove the tentative optimization that resulted in
worse performances and worse code.
