Recently, Coverity has started complaining about using g_free() to free
memory areas allocated by GLib functions not included in model.c,
such as g_strfreev. This unfortunately goes against the GLib
documentation, which suggests that g_malloc() should be matched
with g_free() and plain malloc() with free(); since GLib 2.46 however
g_malloc() is hardcoded to always use the system malloc implementation,
and g_free is just "free" plus a tracepoint. Therefore, this
should not cause any problem in practice.

Use void * for consistency with the actual function; provide a model
for MemoryRegionCache functions and for address_space_rw. These
let Coverity understand the bounds of the data that various functions
read and write even at very high levels of inlining (e.g. pci_dma_read).

Place all files that can be useful to rebuild the Coverity
configuration in scripts/coverity-scan: the existing model
file, and the components setup.
The Markdown syntax was tested with Pandoc (but in any case
is meant more as a human-readable reference than as a part
of documentation).
