83fb360d6a semihosting/guestfd: Remove unused 'semihosting/uaccess.h' header
Nothing in guestfd.c requires "semihosting/uaccess.h" nor "qemu.h".

f14eced5ac semihosting: Rename softmmu_FOO_user() -> uaccess_FOO_user()
Add a check in 'softmmu-uaccess.h' that the header is only
include in system emulation, and rename it as 'uaccess.h'.

Rename the API methods:

  - softmmu_[un]lock_user*() -> uaccess_[un]lock_user*()
  - softmmu_strlen_user() -> uaccess_strlen_user().

Update a pair of comments.

c566080cd3 gdbstub: move syscall handling to new file
Our GDB syscall support is the last chunk of code that needs target
specific support so move it to a new file. We take the opportunity to
move the syscall state into its own singleton instance and add in a
few helpers for the main gdbstub to interact with the module.

I also moved the gdb_exit() declaration into syscalls.h as it feels
pretty related and most of the callers of it treat it as such.

e4a4aaa51b semihosting: Create qemu_semihosting_guestfd_init
For arm-compat, initialize console_{in,out}_gf;
otherwise, initialize stdio file descriptors.

This will go some way to cleaning up arm-compat, and
will allow other semihosting to use normal stdio.

5eadbbfca6 semihosting: Split out semihost_sys_close
Split out the non-ARM specific portions of SYS_CLOSE to a
reusable function.  This handles all GuestFD.

Note that gdb_do_syscall %x reads target_ulong, not int.

5b3f39cb04 semihosting: Split out semihost_sys_open
Split out the non-ARM specific portions of SYS_OPEN to a
reusable function.  This handles gdb and host file i/o.

Add helpers to validate the length of the filename string.
Prepare for usage by other semihosting by allowing the
filename length parameter to be 0, and calling strlen.

1c6ff7205b semihosting: Split out guestfd.c
In arm-compat-semi.c, we have more advanced treatment of
guest file descriptors than we do in other implementations.
Split out GuestFD and related functions to a new file so
that they can be shared.
