This patch reverts back to the progress/status behavior of Finit < v3.0
because this is what most users expect, including the maintainer. The
resulting code and configure script is a lot simpler to understand and
maintain:
- No more --enable-progress or --enable-progress-classic configure
flags. Instead a progress_style variable in helpers.c that can
be changed at compile time for those that really need it.
- No more 'splash' kernel commnand line option. This turned out to
be *very* confusing to many users who believed it was some sort of
graphical splash screen à la Plymouth.
Also, when Finit debug is enabled we now have a global 'debug' flag
which now alo controls if klogctl() should be called to prevent the
kernel logs to the console or not.

The SysV API compatibility layer gives too little value to be worth
the effort of maintaining it. Users are encouraged to use the
`initctl` tool instead.

The <svc/foo> condition was created to synchronize starting services,
hence the abbreviation. Example: the Quagga ripd needs to start after
the zebra daemon to ensure its UNIX domain socket is active, otherwise
events may be lost.
However, considering that synchronization was implemented with UNIX PID
files, e.g. waiting for /var/run/quagga/zebra.pid to be created, the
condition abbreviation name <svc/foo> was hard to understand by most
newcomers to Finit. To make matters worse, a new feature to track or
even create PID files for services that don't create one themselves,
using the syntax 'pid:/path/to/foo.pid' was added.
Connecting the dots between these wasn't obvious.
This patch renames service conditions pid conditions and also adds
a compatibility wrapper to the Finit .conf parser. Any condition
given in old .conf files with 'svc/' prefix are internally renamed
'pid/', along with a LOG_INFO notice in syslog.

- Changing the GNU defaults is messy. The best way is to leave them
alone and let the user set their install locations themselves.
- Show --exec-prefix in config Summary, that's where the binaries go

This patch adds support for restarting the API socket on SIGHUP, similar
to how SysV init and systemd use SIGUSR1 to restart their FIFO or D-Bus.

This patch adds a rescue (revovery) mode to Finit. Simply add `rescue`
to the kernel cmdline at boot and the following steps at bootstrap will
be skipped:
- Load of services/run/task/etc in /etc/finit.conf + /etc/finit.d/*.conf
- fsck of filesystems in /etc/fstab
- Remount of / to read-write
- Mount of all filesystems in /etc/fstab
- swapon
- A few plugin hooks:
- HOOK_ROOTFS_UP
- HOOK_MOUNT_ERROR
- HOOK_BASEFS_UP
- `runparts DIR`
- /etc/rc.local
Instead of loading /etc/finit.conf and /etc/finit.d/*.conf Finit loads
the file /lib/finit/rescue.conf, which can be overridden by the operator
if needed. If this file is removed (or lost), Finit falls back to start
a simple root shell, without any login.

Finit v3.1 adds support for reloading /etc/finit.conf, document what
actually is read at runtime, compared to at bootstrap, and clarify
which stanzas are for what part of the boot process.

This change removes a long standing kernel requirement and architectural
mishap in the design of Finit v1. It is no longer necessary to include
CONFIG_SYSVIPC in the kernel to use Finit and its command line tool
initctl. It is also no longer possible to connect to the internals of
PID 1 using shmat(), the initctl tool has already been updated to use
the domain socket API.

This patch extends the existing rlimit implementation to support setting
limits per service, run/task, inetd, and tty.
Use rlimit in /etc/finit.conf to change the global setting, which is
then inherited to each /etc/finit.d/*.conf. For each .conf file the
rlimit is reinitialized to the global finit.conf settings.
Also, add `unlimited` keyword, to replace the now deprecated `infinity`
keyword. The latter is however kept, for compatibility with previous
releases, for the foreseeable future.

All this code did was trigger prctl() to set process name to "console",
which you could use as a simple means of figuring out if a process was
started from the system console.
There are other ways to do this, which Finit should not be involved in.
