linux-user: fix 32bit g2h()/h2g()
sparc32plus has 64bit long type but only 32bit virtual address space. For instance, "apt-get upgrade" failed because of a mmap()/msync() sequence. mmap() returned 0xff252000 but msync() used g2h(0xffffffffff252000) to find the host address. The "(target_ulong)" in g2h() doesn't fix the address because it is 64bit long. This patch introduces an "abi_ptr" that is set to uint32_t if the virtual address space is addressed using 32bit in the linux-user case. It stays set to target_ulong with softmmu case.
