Stop storing the generated files for the remote protocol client
and server in source control. The generated files will still be
included in the result of 'make dist' to avoid end-users needing
to generate the files

Unfortunately, this means that the strings marked for translation
in generated files are not picked up by gnulib's syntax-check,
I'm working on fixing that in gnulib.
* .gitignore, cfg.mk, po/POTFILES.in: Reflect deletion.
Always generate the rpc files, and require rpcgen during bootstrap.
* daemon/Makefile.am: Removed generated files with
maintainer-clean target
* src/Makefile.am: Removed generated files with
maintainer-clean target. Always run 'rpcgen' if
generated files are missing
In preparation for removing generated files, it is necessary
to tell automake that the generated files must be distributed
but not directly compiled (since they are included into the
body of a larger .c file that is compiled). Hence, even though
these files are code and not headers in the strict sense of
the word, it is easier to rename them to .h for automake's sake.
* daemon/remote_client_bodies.c: Rename to .h.
* daemon/qemu_client_bodies.c: Likewise.

Likewise.
This patch just covers the simple functions without explicit return
values. There is more to be handled.
The generator collects the members of the XDR argument structs and uses
this information to generate the function bodies.
Exclude the generated files from offending syntax-checks.

Creating a domU on a freshly booted dom0 does not work,
because the libxl driver does not allocate memory for the domU.
After creating a domain with xl libvirt is able to create domains too.
This patch reserves enough memory for the domU first.
The rule of thumb is that any file generated by config.status
is a) reproducible by any user, b) dependent on configure options.
Therefore, it is inappropriate to include such generated files
in the tarball (for proof, Makefile is generated from Makefile.in;
the former is not in the tarball while the latter is).
* Makefile.am (EXTRA_DIST): Remove files covered by AC_OUTPUT.
Users often edit XML file stored in configuration directory
thinking of modifying a domain/network/pool/etc. Thus it is wise
to let them know they are using the wrong way and give them hint.
When setting up a FIFO for QEMU, it allows either a pair
of fifos used unidirectionally, or a single fifo used
bidirectionally. Look for the bidirectional fifo first
when labelling since that is more useful

src/security/security_selinux.c: Fix fifo handling
As well as taint warnings going to the main libvirt log,
add taint warnings to the per-domain logfile
Domain id=3 is tainted: high-privileges
Domain id=3 is tainted: disk-probing
Domain id=3 is tainted: shell-scripts
Domain id=3 is tainted: custom-monitor
* src/qemu/qemu_domain.c, src/qemu/qemu_domain.h: Enhance
qemuDomainTaint to also log to the domain logfile
* src/qemu/qemu_driver.c: Pass -1 for logFD to taint methods to
auto-append to logfile
* src/qemu/qemu_process.c: Pass open logFD at startup for taint
methods
The qemuDomainAppendLog method allows writing a formatted string
to the end of the domain logfile, optionally opening it if needed.
* src/qemu/qemu_domain.c, src/qemu/qemu_domain.h: Add
qemuDomainAppendLog
Move the qemuProcessLogReadFD and qemuProcessLogFD methods
into qemu_domain.c, renaming them to qemuDomainCreateLog
and qemuDomainOpenLog.
* src/qemu/qemu_domain.c, src/qemu/qemu_domain.h: Add
qemuDomainCreateLog and qemuDomainOpenLog.
* src/qemu/qemu_process.c: Remove qemuProcessLogFD
and qemuProcessLogReadFD
Wire up logging of VM tainting to the QEMU driver
- If running QEMU as root user/group or without capabilities
being cleared
- If passing custom QEMU command line args
- If issuing custom QEMU monitor commands
- If using a network interface config with an associated
shell script
- If using a disk config relying on format probing
The warnings, per-VM appear in the main libvirtd logs
11:56:17.571: 10832: warning : qemuDomainObjTaint:712 : Domain id=1 name='l2' uuid=c7a3edbd-edaf-9455-926a-d65c16db1802 is tainted: high-privileges
11:56:17.571: 10832: warning : qemuDomainObjTaint:712 : Domain id=1 name='l2' uuid=c7a3edbd-edaf-9455-926a-d65c16db1802 is tainted: disk-probing
The taint flags are reset when the VM is stopped.
* src/qemu/qemu_domain.c, src/qemu/qemu_domain.h: Helper APIs
for logging taint warnings
* src/qemu/qemu_driver.c: Log tainting with custom QEMU monitor
commands and disk/net hotplug with unsupported configs
* src/qemu/qemu_process.c: Log tainting at startup based on
unsupported configs
Some configuration setups for guests are allowed, but strongly
discouraged and unsupportable in production systems. Introduce
a concept of 'tainting' to virDomainObjPtr to allow such setups
to be identified. Drivers can then log warnings at suitable
times
* src/conf/domain_conf.c, src/conf/domain_conf.h: Declare taint
flags and add parsing/formatting of domain status XML
Print the name of the CA cert, certificate, and key file that resulted
in the failure so that the user has an idea what to troubleshoot.

Match the fact that we have virAsprintf and virVasprintf.
* src/util/buf.h (virBufferVasprintf): New prototype.
* src/util/buf.c (virBufferAsprintf): Move guts...
(virBufferVasprintf): ...to new function.
* src/libvirt_private.syms (buf.h): Export it.
* bootstrap.conf (gnulib_modules): Add stdarg, for va_copy.
We already have virAsprintf, so picking a similar name helps for
seeing a similar purpose. Furthermore, the prefix V before printf
generally implies 'va_list', even though this variant was '...', and
the old name got in the way of adding a new va_list version.
global rename performed with:
$ git grep -l virBufferVSprintf \
| xargs -L1 sed -i 's/virBufferVSprintf/virBufferAsprintf/g'
then revert the changes in ChangeLog-old.
The qemuMigrationToFile method was accidentally annotated for
the 'compressor' parameter to be non-null, instead of the
'path' parameter. Thus GCC with -O2, unhelpfully deleted the
entire 'if (compressor == NULL)' block of code during
optimization. Thus NULL was passed to virCommandNew() with
predictably bad results.
* src/qemu/qemu_migration.h: Fix non-null annotation to be
against path instead of compressor
To cope with the QEMU binary being changed while a VM is running,
it is neccessary to persist the original qemu capabilities at the
time the VM is booted.
* src/qemu/qemu_capabilities.c, src/qemu/qemu_capabilities.h: Add
an enum for a string rep of every capability
* src/qemu/qemu_domain.c, src/qemu/qemu_domain.h: Support for
storing capabilities in the domain status XML
* src/qemu/qemu_process.c: Populate & free QEMU capabilities at
domain startup
* configure.ac libvirt.spec.in docs/news.html.in: update and document
the release
* po/*.po*: update localizations for german, polish, spanish, ukrainian
and vietnamese coming from transifex, regenerate
In Fedora 15, with clang 2.8, 'scan-build env' shows:
CCC_ANALYZER_ANALYSIS=-analyzer-check-objc-mem -analyzer-check-security-syntactic -analyzer-check-dead-stores -analyzer-check-objc-unused-ivars -analyzer-check-objc-methodsigs
But in rawhide, with clang 2.9, the same variable is set but
empty, implying the default set of analysis. We still want
sa_assert defined in that case, to stop clang from hitting
false positives.
* configure.ac (STATIC_ANALYSIS): Detect clang even when the set
of analyses is the default.
