* configure.in: more $pkglibdir -> $libexecdir fixing.
* doc/Makefile.am: add rules for generating ps and text versions of the ctlseqs
	docs.
* doc/reference/tmpl/vte.sgml: add snippet for "commit".
* python/python/vte.defs: update to add a binding for
	vte_terminal_fork_logged_command().
* src/buffer.h: add a warning comment that these are private interfaces.  Wrap
	declarations in G_BEGIN_DECLS/G_END_DECLS.
* src/caps.h: add macros for the SS2/SS3 sequences.
* src/marshal.list: add a marshaller for the "commit" signal.
* src/keymap.c, src/keymap.h: move the getting-more-convoluted keypress-handling
	code to a shell that parses tables of static info.
* src/pty.c: reset signal handlers before exec() (Red Hat #75341)
* src/vte.c: use the keymap for most non-printable keys.  Add a "commit" signal
	to allow an app to just use the terminal for displaying data and
	grabbing input.  Obey the application's desired meta-sends-escape
	setting. ...
