d396a657ba syborg: drop support for Symbian Virtual Platform
The Symbian Virtual Platform was an ARM-based development and debugging
board.  Since Symbian has been disbanded and the code is no longer being
used it can now be removed.

90d8454ed0 QEMUFileCloseFunc: add return value documentation (v2)
qemu_fclose() and QEMUFile->close will return -errno on error, and any
positive value on success.

We need the positive non-zero success values because
migration-exec.c:exec_close() relies on non-zero return values to get
the process exit code.

Changes v1 -> v2:
 - Cosmetic spelling change on comment text

217bfb445b hw/arm_gic.c: Ignore attempts to complete nonexistent IRQs
Ignore attempts to complete non-existent IRQs; this fixes a buffer
overrun if the guest writes a bad value to the GICC_EOIR register.
(This case is UNPREDICTABLE so ignoring it is a valid choice.)
Note that doing nothing if the guest writes 1023 to this register
is not in fact a change in behaviour: the old code would also
always do nothing in this case but in a non-obvious way.
(The buffer overrun was noted by Coverity, see bug 887883.)

922453bca6 block: convert qemu_aio_flush() calls to bdrv_drain_all()
Many places in QEMU call qemu_aio_flush() to complete all pending
asynchronous I/O.  Most of these places actually want to drain all block
requests but there is no block layer API to do so.

This patch introduces the bdrv_drain_all() API to wait for requests
across all BlockDriverStates to complete.  As a bonus we perform checks
after qemu_aio_wait() to ensure that requests really have finished.
