This revises the delta-t implementation to align with Watson's timer
specifications. FRCT will never deliver out-of-order packets. A raw
flow (without delta-t state machine) will be able to provide such a
service.

This allows disabling partial reads. It adds a flag FLOWFRNOPART that
disables partial reads. Partial read is different from partial
delivery (FRCTFPARTIAL), which allows delivery of fragments of an
incomplete packet and thus potentially corrupted data. FLOWFRNOPART
will never deliver corrupted data (unless FRCTFPARTIAL is also set).
If FLOWFRNOPART is set and the buffer provided to flow_read is too
small for the SDU, that SDU will be discarded and -EMSGSIZE is
returned;

This adds the FLOWGRXQLEN and FLOWGTXQLEN operations to fccntl to get
the number of packets that are in the receive and transmit buffers
respectively. The flow statistics are updated to show these queue
lengths.

The FLOWFNONBLOCK flag now has two subflags FLOWFRNOBLOCK and
FLOWFWNOBLOCK which allows setting the behavior of read and write
independently. The default behavior is unchanged (blocking read and
write).

This adds user documentation for the Ouroboros User Manual in man
sections 7 and 8. It consists of a general man page, a tutorial and a
glossary.
It also fixes and updates other manpages in the Ouroboros Programmer's
Manual.

This commit deprecates ouroboros_init and ouroboros_fini and adds them
as a constructor or destructor, causing these function to be run
automatically when a program that links to the library calls and exits
main(). For this to fully work, the library had to be split so that we
can avoid the irmd calling these functions (the IRMd has to create the
shm structures on which these calls depend).
The library is split in 3 parts: libouroboros-dev, libouroboros-irm
and libouroboros-common. The latter is linked to the other two so that
including libouroboros-dev or libouroboros-irm will also link
libouroboros-common.

The option to mark a flow as down was missing from the manpage of
fccntl.
|
|
|
This replaces the flow_set_* commands with a single fccntl command
that can configure flows and the FRCT instance.
For more details, see "man 3 fccntl".
