linux-user: fix O_TMPFILE handling
Since O_TMPFILE might differ between guest and host,
add it to the bitmask_transtbl. While at it, fix the definitions
of O_DIRECTORY etc which should arm32 according to kernel sources.
This fixes open14 and openat03 ltp testcases. Fixes:

linux-user: Allow -R values up to 0xffff0000 for 32-bit ARM guests
The 32-bit ARM validate_guest_space() check tests whether the
specified -R value leaves enough space for us to put the
commpage in at 0xffff0f00. However it was incorrectly doing
a <= check for the check against (guest_base + guest_size),
which meant that it wasn't permitting the guest space to
butt right up against the commpage.
Fix the comparison, so that -R values all the way up to 0xffff0000
work correctly.

tcg: Fix off-by-one in assert in page_set_flags
Most of the users of page_set_flags offset (page, page + len) as
the end points. One might consider this an error, since the other
users do supply an endpoint as the last byte of the region.
However, the first thing that page_set_flags does is round end UP
to the start of the next page. Which means computing page + len - 1
is in the end pointless. Therefore, accept this usage and do not
assert when given the exact size of the vm as the endpoint.

linux-user: Tidy and enforce reserved_va initialization
We had a check using TARGET_VIRT_ADDR_SPACE_BITS to make sure
that the allocation coming in from the command-line option was
not too large, but that didn't include target-specific knowledge
about other restrictions on user-space.
Remove several target-specific hacks in linux-user/main.c.
For MIPS and Nios, we can replace them with proper adjustments
to the respective target's TARGET_VIRT_ADDR_SPACE_BITS definition.
For ARM, we had no existing ifdef but I suspect that the current
default value of 0xf7000000 was chosen with this in mind. Define
a workable value in linux-user/arm/, and also document why the
special case is required.

linux-user/sh4: Reduce TARGET_VIRT_ADDR_SPACE_BITS to 31
The real kernel has TASK_SIZE as 0x7c000000, due to quirks with
a couple of SH parts. But nominally user-space is limited to 2GB.

linux-user: Fix target FS_IOC_GETFLAGS and FS_IOC_SETFLAGS numbers
We were defining TARGET_FS_IOC_GETFLAGS and TARGET_FS_IOC_SETFLAGS
using the host 'long' type in the size field, which meant that
they had the wrong values if the host and guest had different
sized longs. Switch to abi_long instead.
This fixes a bug where these ioctls don't work on 32-bit guests
on 64-bit hosts (and makes the LTP test 'setxattr03' pass
where it did not previously.)
