contrib/plugins/cache.c: Remove redundant check of l2_access

contrib/plugins/cache.c: Remove redundant check of l2_access

In append_stats_line(), we have an expression
l2_access ? l2_miss_rate : 0.0
But this is inside an if (l2_access && l2_misses) { ... } block,
so Coverity points out that the false part of the ?: is dead code.

Remove the unnecessary test.

plugins: remove previous n_vcpus functions from API

This information is already accessible using qemu_info_t during plugin
install.

We will introduce another function (qemu_plugin_num_vcpus) which
represent how many cpus were enabled, by tracking new cpu indexes.

It's a breaking change, so we bump API version.

plugins: fix memory leak while parsing options

It was hard to track down this leak as it was an internal allocation
by glib and the backtraces did not give much away. The autofree was
freeing the allocation with g_free() but not taking care of the
individual strings. They should have been freed with g_strfreev()
instead.

Searching the glib source code for the correct string free function
led to:

G_DEFINE_AUTO_CLEANUP_FREE_FUNC(GStrv, g_strfreev, NULL)

and indeed if you read to the bottom of the documentation page you
will find:

typedef gchar** GStrv;

A typedef alias for gchar**. This is mostly useful when used together with g_auto().

So fix up all the g_autofree g_strsplit case that smugly thought they
had de-allocation covered.

plugins/cache: implement unified L2 cache emulation

This adds an implementation of a simple L2 configuration, in which a
unified L2 cache (stores both blocks of instructions and data) is
maintained for each core separately, with no inter-core interaction
taken in account. The L2 cache is used as a backup for L1 and is only
accessed if the wanted block does not exist in L1.

In terms of multi-threaded user-space emulation, the same approximation
of L1 is done, a static number of caches is maintained, and each and
every memory access initiated by a thread will have to go through one of
the available caches.

An atomic increment is used to maintain the number of L2 misses per
instruction.

The default cache parameters of L2 caches is:

2MB cache size
16-way associativity
64-byte blocks

plugins/cache: supported multicore cache modelling

Multicore L1 cache modelling is introduced and is supported for both
full system emulation and linux-user.

For full-system emulation, L1 icache and dcache are maintained for each
available core, since this information is exposed to the plugin through
`qemu_plugin_n_vcpus()`.

For linux-user, a static number of cores is assumed (default 1 core, and
can be provided as a plugin argument `cores=N`). Every memory access
goes through one of these caches, this approach is taken as it's
somewhat akin to what happens on real setup, where a program that
dispatches more threads than the available cores, they'll thrash
each other
