Evolve keventd from a power_supply-only monitor into a full device
manager capable of replacing mdev/mdevd on embedded systems. This
is the first step towards Finit v5.0 where keventd absorbs devmon.
New capabilities:
- Parse all uevent actions (add, remove, change, bind, unbind)
- Create and remove /dev nodes with subsystem-aware permissions
- Create persistent symlinks in /dev/disk/by-{id,path} and
/dev/input/by-{id,path}, tracked for cleanup on device removal
- Load firmware from /lib/firmware/ via the sysfs loading protocol
- Spawn modprobe for MODALIAS events (async, non-blocking)
- Coldplug support via -c flag (walks /sys/devices to replay events)
- Set dev/* conditions for Finit's service dependency system
The original power_supply monitoring and sys/pwr/ac condition are
preserved.
New files: keventd.h (structures/API), uevent.c (all device logic).
The receive buffer is increased to 8K with a 1MB socket buffer to
reduce event loss during coldplug bursts.

Finit is a fast, simple alternative to SysV init and systemd, designed for small and embedded Linux systems. It can also run on desktop and server systems, like finix.

Note
Finit can run on various Linux distributions, but the bundled install scripts are examples only. They have been tested on amd64 (x86_64) systems with standard configurations.
For embedded systems, see these Buildroot-based examples: myLinux, Infix, or br2-finit-demo.
