centralize buffer length sanity checks, add some utility functions forvte_0_10_6

* src/buffer.c, src/buffer.h: centralize buffer length sanity checks, add some
	utility functions for stuffing things into buffers and pulling them
	back out.
* src/debug.c, src/debug.h: add a lifecycle debug class, for tracking
	down initialization order weirdness.
* src/pty.c: try to check that we can run the pty helper before trying to run
	it, to avoid SIGPIPE failures when it's not installed.
* src/vte.c: never grab focus -- let the shell app deal with it.  Return TRUE
	from mouse motion and press/release events to keep them from being
	passed up.
