console-server: Fix printf() format string for discovered handlers GCC reports the following on ARM: ``` ../../../../../../workspace/sources/obmc-console/console-server.c: In function 'handlers_init': ../../../../../../workspace/sources/obmc-console/console-server.c:549:19: error: format '%ld' expects argument of type 'long int', but argument 2 has type 'size_t' {aka 'unsigned int'} [-Werror=format=] 549 | printf("%ld handler type%s\n", n_types, n_types == 1 ?

To build this project, run the following shell commands:
meson setup build meson compile -C build
To test:
meson test -C build
Running the server requires a serial port (e.g. /dev/ttyS0):
touch obmc-console.conf ./obmc-console-server --config obmc-console.conf ttyS0
To connect to the server, simply run the client:
./obmc-console-client
To disconnect the client, use the standard ~.
combination.
This shows how the host UART connection is abstracted within the BMC as a Unix domain socket.

This supports multiple independent consoles. The console-id
is a unique portion for the unix domain socket created by the obmc-console-server instance. The server needs to know this because it needs to know what to name the pipe; the client needs to know it as it needs to form the abstract socket name to which to connect.
