Implement the changes to the TTBCR register required for LPAE:

Implement the different format of the PAR when long descriptor
translation tables are in use. Note that we assume that
get_phys_addr() returns a long-descriptor format DFSR value on
failure if long descriptors are in use; this added subtlety tips
the balance and makes it worth adding a comment documenting the
API to get_phys_addr().

In the implementation of get_phys_addr(), consistently use
target_phys_addr_t to hold the physical address rather than
uint32_t.

Under LPAE, the cp15 registers PAR, TTBR0 and TTBR1 are extended
to 64 bits, with a 64 bit (MRRC/MCRR) access path to read the
full width of the register. Add the state fields for the top
half and the 64 bit access path. Actual use of the top half of
the register will come with the addition of the long-descriptor
translation table format support.

For the PAR we also need to correct the masking applied for
32 bit writes (there are no bits reserved if LPAE is implemented)
and clear the high half when doing a 32 bit result VA-to-PA
lookup.

Implement the privileged-execute-never (PXN) translation table bit.
It is implementation-defined whether this is implemented, so we give
it its own ARM_FEATURE_ flag. LPAE requires PXN, so add also an
LPAE feature flag and the implication logic, as a placeholder
for actually implementing LPAE at a later date.

Make target_phys_addr_t 64 bits for ARM targets, and set
TARGET_PHYS_ADDR_SPACE_BITS to 40.  This should have no effect for ARM
boards where physical addresses really are 32 bits (except perhaps a
slight performance hit on 32 bit hosts for system emulation) but allows
us to implement the Large Physical Address Extensions for Cortex-A15,
which mean 40 bit physical addresses.

Fix errors in the TCG temp handling in the 64 bit coprocessor
write path: we were reusing a 32 bit temp after it had been
freed by store_reg(), and failing to free a 64 bit temp.

This bug has no visible effect at this point because there
aren't any non-NOP 64 bit registers yet; it needs to be fixed
as a prerequisite for the 64 bit registers in LPAE support.

Make qemu_find_file() check for the passed in name as a straight
pathname even if it doesn't have any path separator character in it.
This means that "-bios foo", "-dtb foo" etc will find a file 'foo'
in the current directory.
This removes an inconsistency with -kernel and -initrd, which both
accept plain filenames as meaning files in the current directory.
It's also less confusing for the user than an undocumented restriction
that "this option accepts a filename, except for the special case
where the filename you pass happens not to have a '/' in it, in
which case we'll ignore it."

By default qemu will use MAP_PRIVATE for guest pages. This will write
protect pages and thus break on s390 systems that dont support this feature.
Therefore qemu has a hack to always use MAP_SHARED for s390. But MAP_SHARED
has other problems (no dirty pages tracking, a lot more swap overhead etc.)
Newer systems allow the distinction via KVM_CAP_S390_COW. With this feature
qemu can use the standard qemu alloc if available, otherwise it will use
the old s390 hack.

Users may pass the following parameters to qemu:
    $ qemu-kvm -net nic -net user,smb= ...
    $ qemu-kvm -net nic -net user,smb ...
    $ qemu-kvm -net nic -net user,smb=bad_directory ...

In these cases, qemu started successfully while samba server
failed to start. Users will confuse since samba server
failed silently without any indication of what it did wrong.

To avoid it, we check whether the shared directory exist and
if users have permission to access this directory when QEMU's
"built-in" SMB server is enabled.

When using guestfwd=, Qemu only connects the virtual server's TCP port
to a single chardev. This is useless in most cases, as we usually want
to have more than a single connection from the guest to the outside world.

This patch adds a new cmd: target to guestfwd= that allows for execution
of a command on every TCP connection. This leverages the same code as
the -smb parameter, just that here the command is user defined.
