When we have a null-terminated array, it would be useful to convert it
or append it to an argv_array for further manipulation.
Implement argv_array_pushv() which will push a null-terminated array of
strings on to an argv_array.

The argv_array_detach function (and associated free() function) was
really only useful for transferring ownership of the memory to a "struct
child_process". Now that we have an internal argv_array in that struct,
there are no callers left.

Allow detaching of ownership of the argv_array's contents and add a
function to free those detached argv_arrays later.
This makes it possible to use argv_array efficiently with the exiting
struct child_process which only contains a member char **argv.
Add to documentation.

Sometimes we build a set of similar command lines, differing
only in the final arguments (e.g., "fetch --multiple"). To
use argv_array for this, you have to either push the same
set of elements repeatedly, or break the abstraction by
manually manipulating the array's internal members.
Instead, let's provide a sanctioned "pop" function to remove
elements from the end.

It can be convenient to push many strings in a single line
(e.g., if you are initializing an array with defaults). This
patch provides a convenience wrapper to allow this.

The submodule code recently grew generic code to build a
dynamic argv array. Many other parts of the code can reuse
this, too, so let's make it generically available.
There are two enhancements not found in the original code:
1. We now handle the NULL-termination invariant properly,
even when no strings have been pushed (before, you
could have an empty, NULL argv). This was not a problem
for the submodule code, which always pushed at least
one argument, but was not sufficiently safe for
generic code.
2. There is a formatted variant of the "push" function.
This is a convenience function which was not needed by
the submodule code, but will make it easier to port
other users to the new code.
