linux-user: Handle TARGET_MAP_STACK and TARGET_MAP_HUGETLB
Add the missing defines and for TARGET_MAP_STACK and TARGET_MAP_HUGETLB
for alpha, mips, ppc, x86, hppa. Fix the mmap_flags translation table
to translate MAP_HUGETLB between host and target architecture, and to
drop MAP_STACK.

Message-Id: <20170311183016.GA20514@ls3530.fritz.box>
[rth: Drop MAP_STACK instead of translating it, since it is ignored
in the kernel anyway. Fix tabs to spaces.]
