After forking off a new child, all signals that are blocked by finit
should be unblocked before exec-ing the final binary. Also, finit now
blocks SIGHUP, so add it to the set of signals that should be
unblocked.
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.

Check return code from `mount -na`, if there where any errors give
plugins a chance to do something about it.

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 makes it possible to build Finit with an external libite.
Without this configure script option the libite submodule is used.
With an external libite we make sure to set the SONAME to libite.so.2
to prevent runtime ABI issues with older libite versions.

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.

This part of the README must be completely overhauled before the
release, so much of the contents is basically just TODO or design
ideas atm.
