Avi Kivity a8170e5e97 Rename target_phys_addr_t to hwaddr
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

Jim Meyering 9b9e3ec1b4 doc: update HACKING wrt strncpy/pstrcpy
Reword the section on strncpy: its NUL-filling is important
in some cases.  Mention that pstrcpy's signature is different.

Peter Maydell f603a687ff HACKING: clarify allocation/free recommendations
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.

Stefan Weil 417131fb9a HACKING: Update status of format checking
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Therefore the last comment in HACKING is no longer valid but misleading.
