31dbbf3274 usr/fileio: Suppress a Coverity complaint about 'page_size' 
Suppress the following Coverity complaint:

    CID 361202:  Error handling issues  (NEGATIVE_RETURNS)
    "page_size" is passed to a parameter that cannot be negative.

6c785d14b9 usr/fileio/fileio: Fix align_alloc() 
User space code must not use PAGE_SIZE but must use sysconf(_SC_PAGESIZE)
instead to obtain the page size.

fda71c077d Include <poll.h> instead of <sys/poll.h> 
According to the Single Unix Specification, the poll() function has been
declared in the <poll.h> header file. This makes the SCST code compatible
with the musl C library. See also https://en.wikipedia.org/wiki/Musl. See
also https://github.com/bvanassche/scst/issues/23.

5a9a0ad491 2 missed functions added to scst_user interface: 
- SCST_USER_UNREGISTER_DEVICE - to unregister device, flush mem reuse (SGV) cache and send UCMD_STATE_ON_CACHE_FREEING notifications for all freed buffers to the user space handler. Simple device close doesn't allow that, so all the cached buffers might look as "leaked" from the user space handler POV.

 - SCST_USER_FLUSH_CACHE - to flush mem reuse (SGV) cache and send UCMD_STATE_ON_CACHE_FREEING notifications for all freed buffers to the user space handler

+ some cosmetics

Docs update is coming
