Declare the variable in the scope it is used rather than the entire
function scope so it's obvious it is only used there.

Some people like to use ${?} rather than $?, so make sure we support all
the special single char vars that use this form.

The getopt function in some C libraries wraps the option in single quotes
while others do not. Avoid the issue by running sed on the output and
strip all quotes.

Implement support for the POSIX `type` command. Only POSIX stuff is
supported here, no bash extensions like -p or -P.
In the process, split the $PATH searching code out of builtin_source() and
into its own find_in_path() function so we don't duplicate it.
