Commit 2e679780ae replaced strncpy() with pstrcpy()
in one place in libcacard. This is a qemu-specific function,
while libcacard is a stand-alone library (or tries to be).
But since we know the exact length of the string to copy,
and know that it definitely will fit in the destination
buffer, use memcpy() instead, and null-terminate the string
after that.
An alternative is to use g_strlcpy() or strncpy(), but memcpy()
is more than adequate in this place.

glib >= 2.31 always enables thread support and g_thread_supported()
is #defined to 1, there's no need to call g_thread_init() anymore,
and it definitely does not need to report error which never happens.
Keep code for old < 2.31 glibc anyway for now, just #ifdef it
differently.

The test_path binary is (unlike the other test binaries in tests/tcg)
actually intended to be compiled with the same compiler used to build
the main QEMU executables. It actually #includes a number of the
QEMU source files in an attempt to unit-test the util/path.c functions,
and so if it is not compiled with the same compiler used by configure
to set CONFIG_ settings then it is liable to fail to build.
Fix the makefile to build it with the default C compiler rules, not
CC_I386, and fix the test itself not to include a lot of unnecessary
trace related source files which cause the build to fail if the trace
backend is anything other than 'simple'.

Implement discard support for xen_disk. It makes use of the existing
discard code in qemu.
The discard support is enabled unconditionally. The tool stack may
provide a property "discard-enable" in the backend node to optionally
disable discard support. This is helpful in case the backing file was
intentionally created non-sparse to avoid fragmentation.

When source directory can be arrived at by two paths,
configure might misdetect an out of tree build.
The simplest way to trigger the problem is running
configure using a full path. E.g. (<firstpath> refers to qemu source
tree):
ln -s <firstpath> <secondpath>
cd <firstpath>
<secondpath>/configure
A more practical way is when make runs configure automatically:
1. cd <firstpath>/; ./configure
SRC_PATH=<firstpath>/ is written into config_host.mak
2. cd <secondpath>/; touch configure; make
make now runs <firstpath>/configure, so configure
assumes it's an out of tree build
When this happens configure overwrites parts of
the current tree with symlinks.
Make the test more robust: look for configure
in the current directory.
If there - we know it's a source build!

Adding addresses to MAINTAINERS, as agreed on the last conference call:
http://wiki.qemu.org/SecurityProcess
People sometimes detect security issues in upstream
QEMU and don't know where to report them in a non-public way.
Of course whoever just wants full disclosure can just go public,
but there's nothing specified for non-public - until recently Anthony
was doing this informally.
As I started doing this recently anyway, I can handle this on the QEMU side
in a more formal way.
Adding a secalert mailing list as well - they are the ones who is actually
opening CVEs, communicating issues to all downstreams etc,
and they are already handling this for upstream, not just Red Hat.
Keeping Anthony's address around in case he wants to be informed.
Peter Maydell said that he prefers not to be on this contact list at
this point.
A public mailing list has been created - not listing it here yet -
until we know how to set it up in a secure fashion and
until there are more people so manually copying everyone
becomes unwieldy for reporters.

Pirqs are not freed when driver unload, then new pirqs are allocated when
driver reload. This could exhaust pirqs if do it in a loop.
This patch fixes the bug by freeing pirqs when ENABLE bit is cleared in
msi/msix control reg.
There is also other way of fixing it such as reuse pirqs between driver reload,
but this way is better.

The address_space_translate() function cuts the returned plen (page size)
to hardcoded TARGET_PAGE_SIZE. This function can be used on pages bigger
than that so this limiting should not be used on such pages.
Since originally the limiting was introduced for XEN, we can safely
limit this piece of code to XEN. So does the patch.
