H A Dnxt_router.cdiff 1321:2c7f79bf0a1f Tue Dec 24 15:04:00 UTC 2019 Max Romanov <max.romanov@nginx.com> Introducing port messages to notify about out of shared memory.

- OOSM (out of shared memory). Sent by application process to router
when application reaches the limit of allocated shared memory and
needs more.
- SHM_ACK. Sent by router to application when the application's shared
memory is released and the OOSM flag is enabled for the segment.

This implements blocking mode (the library waits for SHM_ACK in case of
out of shared memory condition and retries allocating the required memory
amount) and non-blocking mode (the library notifies the application that
it's out of shared memory and returns control to the application module
that sets up the output queue and puts SHM_ACK in the main message loop).
