linux-user: Fix unlock_user() call in return from poll()

Correct the broken attempt to calculate the third argument
to unlock_user() in the code path which unlocked the pollfd
array on return from poll() and ppoll() emulation. (This
only caused a problem if unlock_user() wasn't a no-op, eg...

linux-user: Fix large seeks by 32 bit guest on 64 bit host

When emulating a 32 bit Linux user-mode program on a 64 bit target
we implement the llseek syscall in terms of lseek. Correct a bug
which meant we were silently casting the result of host lseek()...

linux-user: fix compile failure if !CONFIG_USE_GUEST_BASE

If CONFIG_USE_GUEST_BASE is not defined, gcc complains:
linux-user/mmap.c:235: error: comparison of unsigned expression >= 0 is always true

because RESERVED_VA is #defined to 0. Since mmap_find_vma_reserved()...

linux-user: in linux-user/strace.c, tswap() is useless

Syscall parameters are already swapped by the caller.

This patch removes useless tswap() from strace.c

$ QEMU_STRACE=1 chroot /m68k mknod myramdisk b 1 1
with tswap()
...

linux-user: Support the epoll syscalls

Support the epoll family of syscalls: epoll_create(), epoll_create1(),
epoll_ctl(), epoll_wait() and epoll_pwait(). Note that epoll_create1()
and epoll_pwait() are later additions, so we have to test separately
in configure for their presence....

linux-user: correct core dump format

This patch allows to really use the core dumped by qemu with guest
architecture tools.

- it adds a missing bswap_phdr() for the program headers
of memory regions.

"objdump -x" sample:

BEFORE:

0x1000000 off 0x00200000 vaddr 0x00000400 paddr 0x00000000 align 2**21...

linux-user/arm: fix compilation failures using softfloat's struct types

Add uses of the float32/float64 boxing and unboxing macros so that
the ARM linux-user targets will compile with USE_SOFTFLOAT_STRUCT_TYPES
enabled.

linux-user: fix build errors for mmap2-only ports

The current print_mmap func is only enabled when the target supports the
mmap syscall, but both mmap and mmap2 syscalls use it. This leads to a
build failure when the target supports mmap2 but not mmap.

linux-user: fix for loopmount ioctl

In case a chrooted build uses XEN or KVM, a looped mount needs to be done to setup the chroot.
The ioctl for loop mount works correctly for arm, mips, ppc32 and sh4, so its now activated.
