* lisp/ob-shell.el: added support to serialize vars as arrays or associative arrays as appropriate if it is using bash.
* testing/examples/ob-shell-test.org: a file containing a few code blocks both illustrating the use of arrays as well as serving as test for the new export functionality.
* testing/lisp/test-ob-shell.el: added a few unit tests that verify that this new logic only triggers for bash and no other shell at this time.
When variables are defined in a 'sh' code block, they are exported as strings. when the variable itself is an array or a table, then we simply get a shell variable that contains the list of all values in a non-structured form.
When calling the code block with bash, however, it will now export the list as an array, the table as an associative array. A scalar is exported the same way as before.

* lisp/ob-sh.el (org-babel-variable-assignments:sh): Check for
":hlines yes" and use header arg :hlines-string if
defined (default to "hline") and add this to the call of
`org-babel-sh-var-to-sh'.
(org-babel-sh-var-to-sh, org-babel-sh-var-to-string): Add additional
optional string argument `hline' and use it for the :hline parameter
in the call to `orgtbl-to-generic'.
* lisp/ob-shell.el (org-babel-execute:shell): Pass the cmdline header
argument to `org-babel-sh-evaluate'.
(org-babel-sh-evaluate): Pass the cmdline header argument to
`call-process-shell-command'.
