qom: aggressively optimize qom casting
This patch adds a small typename cache to ObjectClass. This allows
caching positive casts within each ObjectClass. Benchmarking a
PPC workload provided by Aurelien, this patch eliminates every
single g_hash_table_lookup() happening during the benchmark (which
was about 2 million per-second).
With this patch applied, I get exactly the same performance (within
the margin of error) as with --disable-qom-cast-debug.
N.B. it's safe to cache typenames only from the _assert() macros
because they are always called with string literals.

spitz: fix compilation failure due to pty.h namespace pollution
pty.h is polluting the global namespace with a CTRL macro. spitz
thus fails compilation with the patch at
http://article.gmane.org/gmane.comp.emulators.qemu/211337 and
this patch fixes it.

osdep: introduce qemu_anon_ram_free to free qemu_anon_ram_alloc-ed memory
We switched from qemu_memalign to mmap() but then we don't modify
qemu_vfree() to do a munmap() over free(). Which we cannot do
because qemu_vfree() frees memory allocated by qemu_{mem,block}align.
Introduce a new function that does the munmap(), luckily the size is
available in the RAMBlock.
