Alex Bennée 95992b674c bsd-user: align use of mmap_lock to that of linux-user
The introduction of stricter mmap_lock checking in translate-all broke
the BSD user build. The working mmap_lock functions were hidden behind
CONFIG_USE_NPTL which is never defined. This patch brings them inline
with linux-user.

Despite the disapearence of the comment "We aren't threadsafe to start
with..." this doesn't make bsd-user so. It will still need the rest of
the fixes that have been done in linux-user ported over.

Paolo Bonzini c8645752ce configure: remove Cygwin
The Cygwin target is really compiling for native Win32 with -mno-cygwin.
Except, GCC 4.7.0 has finally removed the long deprecated -mno-cygwin
option, and that happened about five years ago.

Let it rest in peace.

Alex Bennée 301e40ed80 translate-all: add DEBUG_LOCKING asserts
This adds asserts to check the locking on the various translation
engines structures. There are two sets of structures that are protected
by locks.

The first the l1map and PageDesc structures used to track which
translation blocks are associated with which physical addresses. In
user-mode this is covered by the mmap_lock.

The second case are TB context related structures which are protected by
tb_lock which is also user-mode only.

Currently the asserts do nothing in SoftMMU mode but this will change
for MTTCG.

Paolo Bonzini 02d0e09503 os-posix: include sys/mman.h
qemu/osdep.h checks whether MAP_ANONYMOUS is defined, but this check
is bogus without a previous inclusion of sys/mman.h.  Include it in
sysemu/os-posix.h and remove it from everywhere else.

Peter Maydell b7b5233ad7 bsd-user/mmap.c: Don't try to override g_malloc/g_free
Trying to override the implementations of g_malloc and g_free is
a really bad idea -- it means statically linked builds fail to
link (because of the multiple definitions provided by this file
and by glib), and non-statically linked builds segfault as soon
as they try to do anything more complicated than printing the
usage message. Remove these overridden versions and just use
the glib ones.

This is sufficient that bsd-user can run basic x86-64
binaries on OpenBSD again; FreeBSD and NetBSD seem to have
further issues.
