Implementation of a Second-Chance replacement policy. Similar to FIFO,
but every block is given a second chance if it has been touched.

Replacement data is specific for each replacement policy, and thus
should be instantiated differently by each policy.
Touch() and reset() do not need to be aware of CacheBlk, as they
only update its ReplacementData.
Invalidate() makes replacement policies independent of cache blocks,
by removing the awareness of the valid state.
An inheritable base ReplaceableEntry class was created to allow usage
of replacement policies with any table-like structure.

With this patch a gem5 System will store more info about its Masters.
While it was previously keeping track of the Master name and Master ID
only, it is now adding a per-Master pointer to the SimObject related to
the Master.
This will make it possible for a client to query a System for a Master
using either the master's name or the master's pointer.

Use block iteration instead of numSets and assoc in print(),
cleanupRefs() and computeStats().
This makes these functions rely solely on what they are used for:
printing and calculating stats of blocks. With the addition of
Sectors an extra indirection level is added, and thus these
functions would be skipping blocks.

change 2a15bfd79ced20a6d4cbf0a0a4c2fbb1444b9a44 introduced
a few bugs in the tlb of the cu. asserts in the gpu tlb
and cu expected the page table lookup() function to return
a bool, and this value was used directly in the gpu tlb's
assert and it was kept in the gpu tlb entry, where later
the cu would assert that it is true.
this change fixes the issue by checking the validity of
the pte pointer returned by lookup() in order to set
the validity of the tlb entry itself.

There are many devices that need to handle reads/writes of different
word sizes. A common pattern is a switch statement that check for the
size of a packet and then calls the corresponding
Packet::(get|set)<uintXX_t> methods. Simplify this by implementing
Packet::(get|set)UintX helper functions.
The getter reads a word of the size specified in the packet and the
specified endianness. The word is then zero-extended to 64
bits. Conversely, the setter truncates the word down to the size
required in the packet and then byte-swaps it to the desired
endianness.

A new InstTracer (TarmacParser) has been implemented. This tracer is
parsing a pre-existing Tarmac trace file [1] while gem5 is running; it
is comparing execution data together with trace data and it is dumping
differences.
This allows to use Tarmac format as a glue between heterogeneous
simuators speaking the same Tarmac language.
Kudos to Giacomo Gabrielli for writing the original tracer.
