When collecting a bootstrap task we need to allow its state machine to
complete before cleaning them out.

During the runlevel change from S --> 2 the state machine will pause,
waiting to collect all S-only tasks/services, before continuing.
When an S-only task/service is collected we therefore need to call the
state machine again so that it can reassert all conditions properly.

We should not let PID 1 fail on systems where Linux is built without
CONFIG_SYSVIPC, or the libc does not support shmget()/shmat().
This workaround implements a fallback to using calloc() for PID 1,
which means the initctl tool will not work properly. A better fix
would be to refactor the shm implementation to instead have initctl
call Finit using api.c for each svc_t. This has been added to the
TODO file as future work.

Building finit with a uclibc-ng-toolchain fails with:
```
../src/helpers.h:53:43: error: unknown type name ‘va_list’
void printv (const char *fmt, va_list ap);
```
This patch enables support for bootstrap services in /etc/finit.d/
Please note, however, that this does not mean that all configuration
directives are now allowed in /etc/finit.d/*.conf -- the intention is
only to simplify distribution setups.

A run stanza blocks operation by calling waitpid(), so it will never be
caught by the service_monitor() function. Hence, we need to clean up
any bootsrap calls after waitpid(), or at least perform a manual state
change.

This patch extends the capabilities of task and run .conf stanzas by
enabling pipes and redirects.
Example:
task [s] echo "foo" | cat >/tmp/bar
run [s] echo "$HOME" >/tmp/secret

This patch aligns the two tty configuration stanzas, thus clear and wait
are now the default for both.
tty [LVLS] <DEV> [BAUD] [noclear] [nowait] [TERM]
tty [LVLS] <CMD> <ARGS> [noclear] [nowait]

This patch makes it possible to disable the "Please press Enter" prompt
when using an external getty. Simply append `nowait` to the .conf entry
and Finit will spawn the getty immediately.
A future patch will add support for `noclear` as well to external getty,
as well as a change in default (=> `wait`) for the built-in getty.

It is strongly recommended to instead use the service stanza to start
XDM/GDM, or use startx after a regular login.
Note: the `user NAME` setting was always reserved for use with startx

The emergency shell is just a Finit debug mode. This patch adresses a
concern from GitHub issue #76, with zombie processes in this mode.
Emergency shell could be further improved, e.g. informing the real Finit
process of each collected child (zombie) to be restarted if needed.
