Improve constructor calling convention; implement timeout and line monitoring

* Capture.xs: Rewrite constructor to optionally take named arguments.
* Makefile.PL: Remove 'subdirs-test_.*' rules.
* capture.h (capture): New structure.  All capture_ functions operate
on it.
* capture.c (capture_new): Change signature. Set line monitoring features
if required.
(capture_DESTROY): Free line buffers and dereference callback references.
* lib/POSIX/Run/Capture.pm: Fix trivial error
(get_lines): New method.
