Richard Henderson 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.

Richard Henderson 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.

Rather that static (and not even inline) functions within a
header, move the functions to semihosting/uaccess.c.

Philippe Mathieu-Daudé 8df9f0c3d7 semihosting: Move hw/semihosting/ -> semihosting/
With the exception of hw/core/, the hw/ directory only contains
device models used in system emulation. Semihosting is also used
by user emulation. As a generic feature, move it out of hw/ directory.
