68f41097b9 Added arrays and other filters 
Arrays, objects, numbers, strings, booleans, nulls, values (non-nulls)
-- these builtins filter out those inputs that don't match the name of
the builtin.

This fixes #322 and #324.

2aa8a43c5b Add a recursive object merge strategy and bind it to * 
This commit adds a jv_object_merge_recursive function, that performs
recursive object merging, and binds it to multiply when applied to
two objects.

Added docs and tests.

Closes #320

fe29d3d3fa Add ?, .[]?, and .. operators 
Make XPath-like `//a/b` recursive structure traversal easier in jq,
which then becomes:

    ..|.a?.b?

The `?` operator suppresses errors about . not being an array or object.
The `..` operator is equivalent to calling the new `recurse_down`
built-in, which in turn is equivalent to

    recurse(.[]?)

Note that `..a` is not supported; neither is `...a`.  That could be add
added, but it doesn't seem worth the trouble of saving the need to type
a '|'.

e0cda536f3 Make null + foo return foo, rather than an error. 
This also allows 'add' to be implemented in jq rather than C.

d5fdf70434 Refactor assignment. 
New version is much more elegant and probably slower. Uses
library functions implemented in jq rather than dedicated opcodes.
