Version 2.0 of the semihosting specification added support for
allowing a guest to detect whether the implementation supported
particular features. This works by the guest opening a magic
file ":semihosting-features", which contains a fixed set of
data with some magic numbers followed by a sequence of bytes
with feature flags. The file is expected to behave sensibly
for the various semihosting calls which operate on files
(SYS_FLEN, SYS_SEEK, etc).
Implement this as another kind of guest FD using our function
table dispatch mechanism. Initially we report no extended
features, so we have just one feature flag byte which is zero.

Currently for the semihosting calls which take a file descriptor

we have effectively two implementations, one for real host files
and one for when we indirect via the gdbstub. We want to add a
third one to deal with the magic :semihosting-features file.
Instead of having a three-way if statement in each of these
cases, factor out the implementation of the calls to separate
functions which we dispatch to via function pointers selected
via the GuestFDType for the guest fd.
In this commit, we set up the framework for the dispatch,

The semihosting code needs accuss to the linux-user only
TaskState pointer so it can set the semihosting errno per-thread
for linux-user mode. At the moment we do this by having some
ifdefs so that we define a 'ts' local in do_arm_semihosting()
which is either a real TaskState * or just a CPUARMState *,
depending on which mode we're compiling for.
This is awkward if we want to refactor do_arm_semihosting()
into other functions which might need to be passed the TaskState.
Restrict usage of the TaskState local by:
* making set_swi_errno() always take the CPUARMState pointer
and (for the linux-user version) get TaskState from that
* creating a new get_swi_errno() which reads the errno
* having the two semihosting calls which need the TaskState
for other purposes (SYS_GET_CMDLINE and SYS_HEAPINFO)
define a variable with scope restricted to just that code

Currently the Arm semihosting code returns the guest file descriptors
(handles) which are simply the fd values from the host OS or the
remote gdbstub. Part of the semihosting 2.0 specification requires
that we implement special handling of opening a ":semihosting-features"
filename. Guest fds which result from opening the special file
won't correspond to host fds, so to ensure that we don't end up
with duplicate fds we need to have QEMU code control the allocation
of the fd values we give the guest.
Add in an abstraction layer which lets us allocate new guest FD
values, and translate from a guest FD value back to the host one.
This also fixes an odd hole where a semihosting guest could
use the semihosting API to read, write or close file descriptors
that it had never allocated but which were being used by QEMU itself.
(This isn't a security hole, because enabling semihosting permits
the guest to do arbitrary file access to the whole host filesystem,
and so should only be done if the guest is completely trusted.)
Currently the only kind of guest fd is one which maps to a
host fd, but in a following commit we will add one which maps
to the :semihosting-features magic data.
If the guest is migrated with an open semihosting file descriptor
then subsequent attempts to use the fd will all fail; this is
not a change from the previous situation (where the host fd
being used on the source end would not be re-opened on the
destination end).

- in AArch32 state, the CBAR register (cp15, opc1=1, CRn=15, CRm=3, opc2=0)
