b1449edb79 configure: Don't build ivshmem tools unless CONFIG_IVSHMEM is set
Don't try to build the ivshmem-server and ivshmem-client tools unless
CONFIG_IVSHMEM is set.

This fixes in passing a build bug on NetBSD, which fails to build the
ivshmem tools because they use shm_open() and on NetBSD that requires
linking against -lrt.

6c5359e161 pc-bios/s390: add s390-netboot.img
It's already possible to do a network boot of an s390x guest with an
external netboot image based on a Linux installation, but it would
be much more convenient if the s390-ccw firmware supported network
booting right out of the box, without the need to assemble such an
external image first.

This is an s390-netboot.img that can be used for network booting.
You can download a combined kernel + initrd image via TFTP
by starting QEMU for example with:

 qemu-system-s390x ... -device virtio-net,netdev=n1,bootindex=1 \
       -netdev user,id=n1,tftp=/path/to/tftp,bootfile=kernel.img

Note that this version does not support downloading via config
files (i.e. pxelinux config files or .INS config files) yet. This
will be added later.

49cc0340f8 vhost-user-scsi: Introduce a vhost-user-scsi sample application
This commit introduces a vhost-user-scsi backend sample application. It
must be linked with libiscsi and libvhost-user.

To use it, compile with:
  $ make vhost-user-scsi

And run as follows:
  $ ./vhost-user-scsi -u vus.sock -i iscsi://uri_to_target/
  $ qemu-system-x86_64 --enable-kvm -m 512 \
      -object memory-backend-file,id=mem,size=512m,share=on,mem-path=guestmem \
      -numa node,memdev=mem \
      -chardev socket,id=vhost-user-scsi,path=vus.sock \
      -device vhost-user-scsi-pci,chardev=vhost-user-scsi \

The application is currently limited at one LUN only and it processes
requests synchronously (therefore only achieving QD1). The purpose of
the code is to show how a backend can be implemented and to test the
vhost-user-scsi Qemu implementation.

If a different instance of this vhost-user-scsi application is executed
at a remote host, a VM can be live migrated to such a host.

When doing a "make -j10" in the vanilla QEMU source tree (without
running "configure" first), the Makefile currently generates two

happen, so let's only build the generated files if config-host.mak

bd7f974796 qapi: Clean up build of generated documentation
Rename intermediate qemu-qapi.texi to qemu-qmp-qapi.texi to match its
user qemu-qmp-ref.texi, just like qemu-ga-qapi.texi matches
qemu-ga-ref.texi.

Build the intermediate .texi next to the sources and the final output
in docs/ instead of dumping them into the build root.

Fix version.texi dependencies so that only the targets that actually
need it depend on it.

8755b4afbd trace: ensure $(tracetool-y) is defined in top level makefile
The build rules for trace files have a dependancy on $(tracetool-y).
This variable populated in the trace/Makefile.objs file and thus its
definition gets pulled into the top level makefile. This happens too
late in the process though, so by the time $(tracetool-y) is defined,
make has already evaluated $(tracetool-y) in the dependancies and
found it to be empty. The result is that when the tracetool source
is changed, the generated files are not rebuilt. The solution is to
define the variable in the top level makefile too

4f04f13c2a makefile: merge GENERATED_HEADERS & GENERATED_SOURCES variables
The only functional difference between the GENERATED_HEADERS
and GENERATED_SOURCES variables is that 'Makefile' has a
dependancy on GENERATED_HEADERS, causing generated header files
to be created immediatey at the start of the build process.
There is no reason why this early creation should be restricted
to the .h files, and not include .c files too. Merge both of
the variables into a single GENERATED_FILES variable to make
it clear it is for any type of generated file.

fea346f569 Makefile: Put VERSION info into version.texi rather than using -D
Unfortunately some older versions of makeinfo don't correctly
handle the -D command line option and fail to set the variable.
This then causes them to complain
 docs/qemu-ga-ref.texi:41: warning: undefined flag: VERSION

Work around this by doing as the autotools do, and writing
the information into a version.texi file which we then
include from the .texi files that need it.

d9e73d32a8 Makefile: avoid leaving the temporary QEMU_PKGVERSION header file
By commit 67a1de0d, When we perform 'git pull && make && sudo make install',
In 'make' stage a qemu-version.h.tmp will be generated. If the content of
qemu-version.h.tmp and qemu-version.h aren't consistent, The qemu-version.h.tmp
will be renamed to qemu-version.h. Because of the target FORCE, The same action
will be do again in 'make install' stage.

In 'make install' stage, If there is no qemu-version.h.tmp exists and we run
'make install' with sudo, The owner and group of new qemu-version.h.tmp will be
privileged user/group. When we run 'make' next time, qemu-version.h.tmp can't
be overwritten because of permission issue.

This patch removed qemu-version.h.tmp after build to fix this issue.

the trace.g file in the current sub-dir.

commit f8bab10b4c, it was not added to either the
list of files to remove in distclean or to the dependency
line that forces qemu-options.texi to be built before
attempting to build qemu-doc.*.

In particular, the missing dependency meant that on
some platforms (notably OSX hosts) we would try to
build qemu-doc.txt before qemu-options.texi had been
fully written out, and then makeinfo would complain
about missing cross-reference targets.

7b2e5c65f4 contrib: add libvhost-user
Add a library to help implementing vhost-user backend (or slave).

Dealing with vhost-user as an application developer isn't so easy: you
have all the trouble with any protocol: validation, unix ancillary data,
shared memory, eventfd, logging, and on top of that you need to deal
with virtio queues, if possible efficiently.

qemu test has a nice vhost-user testing application vhost-user-bridge,
which implements most of vhost-user, and virtio.c which implements
virtqueues manipulation. Based on these two, I tried to make a simple
library, reusable for tests or development of new vhost-user scenarios.

347701879c trace: get rid of generated-events.h/generated-events.c
Currently the generated-events.[ch] files contain the
event dstates, constants and TraceEvent structs, while the
generated-tracers.[ch] files contain the actual trace
probe logic. With the removal of usage of the event enums
from the API there is no longer any compelling reason for
the separation between these files. The generated-events.h
content is only ever needed from the generated-tracers.[ch]
files.

The enums/constants/structs from generated-events.[ch] are
thus moved into the generated-tracers.[ch], so that there
is one less file to be generated.

0bdb12c7c5 rules.mak: quiet-command: Split command name and args to print
The quiet-command make rule currently takes two arguments:
the command and arguments to run, and a string to print if
the V flag is not set (ie we are not being verbose).
By convention, the string printed is of the form
"  NAME   some args". Unfortunately to get nicely lined up
output all the strings have to agree about what column the
arguments should start in, which means that if we add a
new quiet-command usage which wants a slightly longer CMD
name then we either put up with misalignment or change
every quiet-command string.

Split the quiet-mode string into two, the "NAME" and
the "same args" part, and use printf(1) to format the
string automatically. This means we only need to change
one place if we want to support a longer maximum name.

In particular, we can now print 7-character names lined
up properly (they are needed for the OSX "SETTOOL" invocation).

Change all the uses of quiet-command to the new syntax.
(Any which are missed or inadvertently reintroduced
via later merges will result in slightly misformatted
quiet output rather than disaster.)

A few places in the pc-bios/ makefiles are updated to use
"BUILD", "SIGN" and "STRIP" rather than "Building",
"Signing" and "Stripping" for consistency and to keep them
below 7 characters. Module .mo links now print "LD" rather
than the nonstandard "LD -r".

88d88798b7 blockdev: Add dynamic module loading for block drivers
Extend the current module interface to allow for block drivers to be
loaded dynamically on request. The only block drivers that can be
converted into modules are the drivers that don't perform any init
operation except for registering themselves.

In addition, only the protocol drivers are being modularized, as they
are the only ones which see significant performance benefits. The format
drivers do not generally link to external libraries, so modularizing
them is of no benefit from a performance perspective.

All the necessary module information is located in a new structure found
in module_block.h

This spoils the purpose of 5505e8b76f (block/dmg: make it modular).

Before this patch, if module build is enabled, block-dmg.so is linked to
libbz2, whereas the main binary is not. In downstream, theoretically, it
means only the qemu-block-extra package depends on libbz2, while the
main QEMU package needn't to. With this patch, we (temporarily) change
the case so that the main QEMU depends on libbz2 again.
