- Upgrade libite (LITE) for new UNIX file parser API to improve static
builds of Finit.
- Re-enable bootmisc plugin for static builds by adding built-in support
for reading GID from /etc/group.
- Allow inetd support for static builds by adding built-in support for
reading service and protocol from /etc/services and /etc/protocols.
- Do not try to install/uninstall any plugins for static builds.

We should not use -Os as default optimization, it is sometimes unstable
in cross compilers. Instead, default to -O2, which is the more tried
and tested path.

When integrating finit as a component in another system, that build
system may set VERSION as an environment variable for that OS -- we do
not want that version to be set as the version of finit.
Also, bump version to 2.0.1-dev for upcoming patch release cycle.

This patch adds a simple `service <script> <stop|start|reload|restart>`
script for for SysV init compatibility. Very common with users of the
Ubuntu upstart init as well.
Also, fixed `make uninstall` for plugins.

Even though libite and libuEv can be disabled, using the --with-libnnn
option to configure, we let make descend into those submodules for the
clean and distclean targets. This way we can rely on make dev to work.

This commit makes it possible to build Finit with an external libuEv.
Without this configure script option the libuev submodule is used.
With an external libuEv we make sure to set the SONAME to libuev.so.1
to prevent any future runtime ABI issues.
Fixes issue #4.

This commit adds support for event based services to Finit. Along with
the previously added support for multiple instances of the same process,
the feature scope for Finit v2.0 has been reached!
As of now a service can be declared in /etc/finit.conf or /etc/finit.d/
like this:
service :1 [2345] <!IFUP:eth0,GW> /sbin/dropbear -R -F -p 22 -- SSH daemon
Here the first instance `:1` of dropbear is declared to run in runlevels
2-5, but only if eth0 `IFUP:eth0` is up and a gateway `GW` is set. When
the configuration changes, a new gateway is set, or somehow a new `IFUP`
event for eth0 is received, then dropbear is not SIGHUP'ed, but instead
stop-started `<!>`. The latter trick applies to all services, even
those that do not define any events.
Currently inetd services are not supported for event based starting, but
it could easily be added. Likely scenario is to deny incoming requests
on, e.g., eth0 if there is no gateway.

The event API, including Netlink events to services, looks OK now
to build the remaining two features on:
- Netlink plugin for GW and IFUP IFDN events
- Generic event support for services

Previously `HOOK_SVC_RECONF` was only called on `initctl reload`,
now we also call it on `initctl emit "STOP"`. This seems like a
good idea atm, hopefully it will remain a good idea.

The tempfile() replacement in Finit leaked temporary files in /tmp.
The mkstemp() based implementation does not remove temporary files

When Finit receives SIGHUP or a reload command all services listed in
/etc/finit.d/*.conf are first stopped and then started again. I.e.,
removed/changed services are stopped and then new/changed services are
started again. In between we call HOOK_SVC_RECONF. It should always be
called, even though no services were removed/changed/added. This to
allow plugins connected to that hook may need to run as intended.

This patch makes it possible to communicate process name or JOB[:ID]
from initctl to Finit. When the process name translates into a service
with multiple instances Finit applies the requested command to all
instances. For example, two Dropbear SSH services running on two
different ports, calling `initctl stop dropbear` stops both services.

When receiving a start/stop/reload/restart request from initctl we must
make sure to validate and NUL terminate the job ID. The `read()` API
does not NUL terminate strings for us and we cannot rely on `initctl` or
any other external API user to do so for us.
This patch improves error and boundary checking.
- Use memcpy() + hard termination instead.
- Fix use of strchr() on possibly non-NUL terminated string.
