astlpc: Provide KCS device path as a binding argument

Currently astlpc binding expects a '/dev/mctp0' device in the system
for the KCS communication. This device is a symbolic link to the
real '/dev/raw-kcsX' device, created by the udev rules populated by the
build system.
This approach is not ideal since the build system populates udev rules
for the KCS3 and KCS4 channels simultaneously and for these channels
only. This means that there are some design limitations for the MCTP
communication. It is only possible on KCS3 or KCS4 channel, and if one
of these channels is used, the other one must be disabled.
To make design more flexible get rid of all the udev rules and provide
'/dev/raw-kcsX' device path as an argument to the binding
initialization code.

mctp-demux-daemon: Add packet capture option

Optionally enable libpcap support in mctp-demux-daemon to capture
packets both from the Unix domain socket and binding interfaces.
Providing the two capture points allows for tracking down issues with
packets being dropped during binding initialisation.

As there's no formal linktype defined for MCTP or higher-level DMTF
protocols command-line switches provide the ability to specify one of
the private linktype values in the range 147-162.

However, this also allows (one) daemon providing services over MCTP

is a stunted way to provide capabilities that might be assumed by other
components (the host) without implementing some required messages from
the MCTP standard.

astlpc: Ship udev rules to help with device and driver transition

Currently the OpenBMC kernel has a hacky device driver at
drivers/char/misc/mctp-lpc.c that only works against KCS channel 4 on
Aspeed BMCs. This hacky driver exposes an `mctp0` device node.

The intent is to replace it with one that is slightly less
hacky at drivers/char/ipmi/kcs_bmc_cdev_raw.c[1], though eventually this
too will be replaced by an in-kernel implementation of the entire LPC
MCTP binding.

kcs_bmc_dev_raw.c works against all KCS devices in both Aspeed and
Nuvoton BMC SoCs.

We need to move away from KCS channel 4 on the Aspeed BMCs as the way
the hardware initialises the status bits conflicts with the protocol
definition for the LPC MCTP binding[2].

Kill two birds with one stone by shipping udev rules that accomodate the
new device node names that come with kcs_bmc_dev_raw.c, and symlink them
upon creation to /dev/mctp0 to emulate the original mctp-lpc.c
interface.

Rework conditional feature usage

Currently, the infrastructure that we have to enable a flexible
compilation environment has a few issues:

- the allocator configuration is performed at run-time, while the log
configuration is performed at compile-time

- for a standard compile (ie, standard userspace, using
autoconf+automake to build), we need a few pre-defined configuration
options.

This change adds a bit of runtime selection to the logging
infrastructure, to match the allocator setup. We also unify the
compile-time defines into config.h, using MCTP_-prefixed macro names,
allowing integration into other build systems.
