Use modified Floyd-Warshall algorithm for cyclic dependecy detection.

This fixes dead loops that occurred in earlier versions when trying to

The "env" statement is now a compound statement. It can contain four
substatements: "clear" to clear the environment, "keep" to retain
certain variable while clearing it, "set" to set a variable, and
"unset" to unset a variable or variables.
Both "keep" and "unset" can take globbing pattern as their argument,
in which case they affect all variable matching that pattern.
The value part in the "set" statement is subject to variable expansion,
e.g.
set "MANPATH=$MANPATH${MANPATH:+:}/usr/local/man"
The support for the old one-line syntax of "env" is retained for
backward compatibility.
This commit also fixes redirection to a file: new data are appended
to the file, instead of overwriting it.

The new flag "shell" instructs pies to run the command marked with it
as '/bin/sh -c $command'. Alternative shell can be supplied ising the
'program' statement.
This is useful if the command line uses shell-specific features (command
or variable expansion, redirection, pipes, etc.)
This commit also fixes a bug in the 'env' statement handling: a single
argument with embedded whitespaces was undergoing word splitting and
thus incorrectly handled as multiple arguments.

* src/comp.c (component_free): Free command.
(component_finish): Split command into argv/argc as directed by the
CF_SHELL flag.

These are components that are run at program startup. Starting
other components is delayed until all startup components terminate.
This is similar to SysV "bootwait" components.
Upon termination, startup components are removed from the configuration.

and plain component_free for inactive ones.

components.

pies_comp_shutdown.

is still running.
