unified concept of function calls. Previously LoB calls were not able to produce results in the buffer. These changes go some way to allowing them to do that. [There are still some bugs to deal with]. That meant changing org-babel.el so that there is a notion of the `source block name' for a LoB line, in order to construct a #+resname (currently I've made the name the same as the function call). I'm also slowly moving towards unifying the notion of `function calls' a bit more: I've changed the org-babel-lob-one-liner-regexp so that instead of a monolithic match it now matches first the function name, and second the function arguments in parentheses. org-babel-lob-get-info makes that match, and although it still concatenates them and returns the string, the two elements can be accessed immediately afterwards using match-string. So that situation is very similar to org-babel-get-src-block-name, whose job (in this branch) is also to parse the function *name* and the function *arguments*. In a few places in the code (esp. function names), I think the word `info' should be replaced with `call' or `function call', which I believe more accurately indicates what the `info' is: a function definition, together with bound arguments/references. The function call syntax, i.e. function-name(arg1=ref1), originally introduced for references (and thereby in LoB), and which I'm proposing we use throughout, raises the question of default arguments, and those being over-ridden by supplied arguments, as in e.g. python, and R.
