Add a section to HACKING saying which version of the C spec
we use and describing the bits of implementation defined C
compiler behaviour which C code in QEMU is allowed to rely on.

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,
standards conformant hwaddr.
Outstanding patchsets can be fixed up with the command
git rebase -i --exec 'find -name "*.[ch]"
| xargs s/target_phys_addr_t/hwaddr/g' origin

Reword the section on strncpy: its NUL-filling is important
in some cases. Mention that pstrcpy's signature is different.

Clarify the allocation/free recommendations; this is mostly
just tidying up following the global-search-and-replace done
with the conversion to the GLib g_malloc and friends.

Hopefully all functions with printf like arguments now use format checking.
This was tested with default build configuration on linux
and windows hosts (including some cross compilations),
so chances are good that there remain few (if any) functions
without format checking.
Therefore the last comment in HACKING is no longer valid but misleading.

Add C type rules, adapted from libvirt HACKING. Also include

Move typedef rule from CODING_STYLE rule 3 to HACKING rule 6
where it belongs.
