2014-06-29linux-user: translate the result of getsockopt SO_TYPEPaul Burton
QEMU previously passed the result of the host syscall directly to the target program. This is a problem if the host & target have different representations of socket types, as is the case when running a MIPS target program on an x86 host. Introduce a host_to_target_sock_type helper function mirroring the existing target_to_host_sock_type, and call it to translate the value provided by getsockopt when called for the SO_TYPE option.

2014-06-27iotests: Fix 083 for out-of-tree buildsMax Reitz
iotest 083 filters out debug messages from nbd, which are prefixed (and recognized) by __FILE__. However, the current filter (/^nbd\.c…/) is valid for in-tree builds only, as out-of-tree builds will have a path before that filename (e.g. "/tmp/qemu/nbd.c"). Fix this by adding .* before "nbd\.c". While working on this, also fix the regexes: '.' should be escaped and a single backslash is not enough for escaping when enclosed by double quotes.

2014-06-27iotests: Drop Python version from 065's ShebangMax Reitz
Test 065 specified python2 to be used in its Shebang; this might not work on systems without a python2 symlink and furthermore it is now counter-productive, as the check script compares the Shebang to "#!/usr/bin/env python" and only uses the Python interpreter selected by configure on an exact match.

2014-06-27iotests: Allow out-of-tree runMax Reitz
As out-of-tree builds are preferred for qemu, running the qemu-iotests in that out-of-tree build should be supported as well. To do so, a symbolic link has to be created pointing to the check script in the source directory. That script will check whether it has been run through a symlink, and if so, will assume it is run in the build tree. All output and temporary operations performed by iotests are then redirected here and, unless specified otherwise by the user, QEMU_PROG etc. will be set to paths appropriate for the build tree. Also, drop making every test case executable if it is not yet, as this would modify the source tree which is not desired for out-of-tree runs and should be fixed in the repository anyway.

2014-06-27block.c: Don't return success for bdrv_append_temp_snapshot() failureChen Gang

This drops request handling code from dataplane, and uses code from hw/block/virtio-blk.c. It starts to use multiwrite as non-dataplane does. Dataplane sets VirtIOBlock.complete_request to vring version, and calls into non-dataplane's process handling.
