0aa8e8cfc3 GDB fileIO stdout support
This patch fixes gdb fileio support to allow gdb console to be used as stdout.

Now we can do something like
gdb <inferior file>

(gdb) tar ext :3333
(gdb) load
(gdb) monitor arm semihosting enable
(gdb) monitor arm semihosting_fileio enable
(gdb) continue

Here: Output from inferior using puts, printf etc will be routed to gdb console.

a7da117ad6 Add ARM v8 AArch64 semihosting support
This patch implements semihosting support for AArch64. This picks
code from previously submitted AArch64 semihosting support patch
and rebases on top of reworked semihosting code. Tested in AArch64
mode on a Lemaker Hikey Board with NewLib and GDB.

2517bae6c1 Rework/update ARM semihosting
In 2016, ARM released the second edition of the semihosting specs
("Semihosting for AArch32 and AArch64"), adding support for 64-bits.

To ease the reuse of the semihosting logic for other platforms
(like RISC-V), the semihosting code was isolated from the ARM
target and updated to the latest specs.

The new code is already in use since January (in GNU MCU Eclipse
OpenOCD) and no problems were reported, neither for ARM nor for
RISC-V targets, after more than 7K downloads.

The 2 new files were formatted with uncrustify.
