[PATCH v5 0/2] plugins/cache: multicore cache modelling

[Mahmoud Mandour <ma.mandourr@gmail.com>]

Hello,

This series introduce multicore cache modelling in contrib/plugins/cache.c

Multi-core cache modelling is handled such that for full-system
emulation, a private L1 cache is maintained to each core available to
the system. For multi-threaded userspace emulation, a static number of
cores is maintained for the overall system, and every memory access go
through one of these, even if the number of fired threads is more than
that number.

v4 -> v5:
    1. Reserved a mutex lock for each cache structure; now callbacks generated
    by accesses done by different vcpus don't block each other.
    2. Used atomic increment to access hashtable entries instead of locking.
    3. Renamed mtx to hashtable_lock to reflect its job more explicitly.
    4. Dropped the usage of CoreStats, embedded stats in the cache structure.
    4. append_stats_line now takes the stats explicitly.
