Nicolas Williams 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 '|'.

Nicolas Williams 99f170adc3 Fix version for make dist on master 
- Re-remove VERSION file and all traces of it
 - Pass a decent version indicator to AC_INIT (using git describe)

When we tag 1.4 this will produce 1.4 as the version string when
building on the HEAD of that tag.

Nicolas Williams a71138a43a Add jv_dumpf() and jv_show() 
jv_dumpf() takes a FILE *.

jv_show() is intended for use in debuggers, so it dumps the jv to stderr
and it does not jv_free() the jv, so it's safe to
"call jv_show(some_jv, -1)" in a debugger.  If flags == -1 then the jv
will be shown pretty-printed and in color.

input data.

    5
    % echo '"a"'|./jq --argfile f /tmp/a '$f[.]'
    1
