232 is marked as generic, but commit 12efe428c9e added code that assumes

updating the backing file link (.bdrv_change_backing_file).

Merge remote-tracking branch 'remotes/palmer/tags/riscv-for-master-4.0-sf4' into staging

target/riscv: Convert to decodetree

Bastian: this patchset converts the RISC-V decoder to decodetree in four major steps:

1) Convert 32-bit instructions to decodetree [Patch 1-15]:
Many of the gen_* functions are called by the decode functions for 16-bit
and 32-bit functions. If we move translation code from the gen_*
functions to the generated trans_* functions of decode-tree, we get a lot of
duplication. Therefore, we mostly generate calls to the old gen_* function
which are properly replaced after step 2).

Each of the trans_ functions are grouped into files corresponding to their
ISA extension, e.g. addi which is in RV32I is translated in the file
'trans_rvi.inc.c'.

2) Convert 16-bit instructions to decodetree [Patch 16-18]:
All 16 bit instructions have a direct mapping to a 32 bit instruction. Thus,
we convert the arguments in the 16 bit trans_ function to the arguments of
the corresponding 32 bit instruction and call the 32 bit trans_ function.

3) Remove old manual decoding in gen_* function [Patch 19-29]:
this move all manual translation code into the trans_* instructions of
decode tree, such that we can remove the old decode_* functions.

Palmer: This, with some additional cleanup patches, passed Alistar's
testing on rv32 and rv64 as well as my testing on rv64, so I think it's
good to go. I've run my standard test against this exact tag.

I still don't have a Mac to try this on, sorry!

file-posix: Make auto-read-only dynamic

Until now, with auto-read-only=on we tried to open the file read-write
first and if that failed, read-only was tried. This is actually not good
enough for libvirt, which gives QEMU SELinux permissions for read-write
only as soon as it actually intends to write to the image. So we need to
be able to switch between read-only and read-write at runtime.

This patch makes auto-read-only dynamic, i.e. the file is opened
read-only as long as no user of the node has requested write
permissions, but it is automatically reopened read-write as soon as the
first writer is attached. Conversely, if the last writer goes away, the
file is reopened read-only again.

bs->read_only is no longer set for auto-read-only=on files even if the
file descriptor is opened read-only because it will be transparently
upgraded as soon as a writer is attached. This changes the output of
qemu-iotests 232.
