Redefining a domain via virDomainDefineXML should not give different results
based on an already existing definition.

Since qemuDomainDeviceDefPostParse callback requires qemuCaps, we need
to make sure it gets the capabilities stored in the domain's private
data if the domain is running. Passing NULL may cause QEMU capabilities
probing to be triggered in case QEMU binary changed in the meantime.
When this happens while a running domain object is locked, QMP event
delivered to the domain before QEMU capabilities probing finishes will
deadlock the event loop.

QEMU capabilities lookup (via domainPostParseDataAlloc callback) is
hidden inside virDomainDeviceDefPostParseOne with no way to pass
qemuCaps to virDomainDeviceDef* functions. This patch fixes all
remaining paths leading to virDomainDeviceDefPostParse.

Due to latest rewrite of NSS module, we are doing yajl parsing
ourselves. This means, we had to introduce couple of callback
that yajl calls. According to its documentation, a callback can
cancel parsing if it returns a zero value. Well, we do just that
in the string callback (findLeasesParserString()). If the JSON
file we are parsing contains a key that we are not interested in,
zero is returned meaning stop all parsing. This is not correct,
because the JSON file can contain some other keys which are not
harmful for our address translation (e.g. 'client-id').

The AM_CPPFLAGS setting includes the gnulib headers, which
means we can get some replacement functions defined. Since
virt-login-shell and the NSS module intentionally don't link
to gnulib, these replacement functions causes link failures.

This was seen cross-compiling on Debian for example:

virt-login-shell.o: In function `main':
/builds/libvirt/libvirt/build/tools/../../tools/virt-login-shell.c:81: undefined reference to `rpl_strerror'
/builds/libvirt/libvirt/build/tools/../../tools/virt-login-shell.c:66: undefined reference to `rpl_strerror'
/builds/libvirt/libvirt/build/tools/../../tools/virt-login-shell.c:75: undefined reference to `rpl_strerror'

The only way to avoid these replacement gnulib headers is
to drop the -Ignulib/lib flags. We do still want to use
gnulib for configmake.h and intprops.h, but those can be
included via their full path.

We must also stop using internal.h, since that expects
-Ignulib/lib to be on the include path in order to resolve
the verify.h header.

Commit fed58d83 was a hack to fix a mingw build failure due to header
inclusion order resulting in a clash over the use of DATADIR,
repeating a trick made several other times in the past.  Better is to
revert that, and instead use pragmas to avoid the clash in the first
place, regardless of header ordering, solving it for everyone.
