Erik Gabriel Carrillo [Mon, 15 Apr 2019 21:41:27 +0000 (16:41 -0500)]
timer: allow management in shared memory

Currently, the timer library uses a per-process table of structures to
manage skiplists of timers presumably because timers contain arbitrary
function pointers whose value may not resolve properly in other
processes.

However, if the same callback is used handle all timers, and that
callback is only invoked in one process, then it woud be safe to allow
the data structures to be allocated in shared memory, and to allow
secondary processes to modify the timer lists.  This would let timers be
used in more multi-process scenarios.

The library's global variables are wrapped with a struct, and an array
of these structures is created in shared memory.  The original APIs
are updated to reference the zeroth entry in the array. This maintains
the original behavior for both primary and secondary processes since
the set intersection of their coremasks should be empty [1].  New APIs
are introduced to enable the allocation/deallocation of other entries
in the array.

New variants of the APIs used to start and stop timers are introduced;
they allow a caller to specify which array entry should be used to
locate the timer list to insert into or delete from.

Finally, a new variant of rte_timer_manage() is introduced, which
allows a caller to specify which array entry should be used to locate
the timer lists to process; it can also process multiple timer lists per
invocation.
