Michał Łyszczek 19e2ffe37e system/psmq: update to v0.2.1
This release breaks API and ABI by making use of library way
easier and more safe. No app in a nuttx tree uses psmq, so
nothing in-tree will be broken by this change.

Updated license files to Apache 2.0.

Tested on nucleo-f091

psmq is tool set which allows IPC communication in publish/subscribe way
created on top of posix messege queue. Full documentation is available
at: https://psmq.bofc.pl (despite the domain, it is in english).
Library is licensed under BSD 2-clause license. See LICENSE file in
the downloaded code for license details.
if SYSTEM_PSMQ
config PSMQ_MAX_CLIENTS
int "Max number of clients"
default 8
---help---
This defines how many clients single broker process will
support. Broker will return error for clients that want to
register to it and there are already max clients connected. psmqd
will allocate client array with static storage duration that is
about 12 bytes (may vary depending on architecture) for each
client.
config PSMQ_MSG_MAX
int "Max size of payload"
range 6 2147483647
default 24
---help---
Defines maximum size of message that can be sent via psmq.
Message consists of topic and payload. Topic is always
null-terminated after which payload follows. This allows
for some flexibility, ie if PSMQ_MSG_MAX was be 10, then
topic could be 3 bytes long and payload 7, but also
topic could take 9 bytes and payload only 1.
This value has direct impact on runtime memory usage by
psmq as this increases size of struct that is used when
allocating memory for client. This has no impact on
number of bytes that are sent because only actual data
is sent over mqueue.

int "psmqd broker task priority"
default 100
config PSMQD_STACKSIZE
int "psmqd broker stack size"

---help---
Enables program which allows to publish message over psmq directly
from command line.

---help---
Enables program which allows to listen to published messages on
chosen topics. It also has capabilities to log these messages to
a chosen file.
