* Join similar imports
Avoid the confusion that might cause one to think that they come from
different modules or crates.
* Create an `Arguments` helper type
A type to keep track of a list of arguments for a sub-process. It makes
it easier for overriding parameters with new values.
* Create an `args!` helper macro
Make it simpler to create `Arguments` instances with known values.
* Require `Arguments` for `spawn_child` method
Change the method to have an `Arguments` parameter, and merge it with
some default values before passing them forward.
* Use `Arguments` in `spawn_lightwalletd_child`
Change the method to use an `Arguments` instance, and merge it with some
default options.
* Use `Arguments` in `spawn_child_with_command`
Require an `Arguments` instance in the `spawn_child_with_command`
extension method. Makes it simpler to call from `spawn_child` and
`spawn_lightwalletd_child` extension methods.
* Test if argument order is preserved
Check that when building an `Arguments` instance, the order that the
arguments are set is preserved in the generated list of strings.
* Refactor test to improve readability
Also separates some common code to be reused by later tests.
* Test overriding arguments
Check to see if overriding arguments behaves as expected, by keeping the
argument order when overriding and not introducing duplicates.
* Refactor test to improve readability
Move out a chunk of code so that the test itself is easier to read and
to make that code reusable by a later test.
* Test that `Arguments` instances can be merged
Merge two `Arguments` instances built from two lists of arguments, and
check that the expanded strings preserve order and override rules.
* Add Eq derives on Arguments

* Revert "Revert Option<Child> process handling"
This reverts commit 2af30086858d104dcb0ec87383996c36bcaa7371.
* Add a set of failure regexes to test command output
* Allow debug-printing TestChild again
* When the child is dropped, check any remaining output
* Document a wait_with_output edge case
* Improve failure regex panic output
* Improve builder ergonomics
* Add internal tests for failure regex panics
It would be easy to disable these panics, and never realise.
* Add some module structure TODOs
* Stop panicking if the child process has already been taken
* Add test APIs for consuming child output lines
* Fix a hang on child process drop
* Handle output being already taken in wait_with_output
And document some edge cases we don't handle yet
* Use bash's read command in the TestChild stderr test
And check the actual command we're using to see if it errors.
* Pretty print full failure regex list
* Add the test child command line to the failure regex logs
