Some of the test suites use fprintf with format specifiers
that are not supported on Win32 and are not fixed by gnulib.
The mingw32 compiler also has trouble detecting ssize_t
correctly, complaining that 'ssize_t' does not match
'signed size_t' (which it expects for %zd). Force the
cast to size_t to avoid this problem
* tests/testutils.c, tests/testutils.h: Fix printf
annotation on virTestResult. Use virVasprintf
instead of vfprintf
* tests/virhashtest.c: Use VIR_WARN instead of fprintf(stderr).
Cast to size_t to avoid mingw32 compiler bug

This provides a new struct that contains a buffer for the RPC
message header+payload, as well as a decoded copy of the message
header. There is an API for applying a XDR encoding & decoding
of the message headers and payloads. There are also APIs for
maintaining a simple FIFO queue of message instances.
Expected usage scenarios are:
To send a message
msg = virNetMessageNew()
...fill in msg->header fields..
virNetMessageEncodeHeader(msg)
...loook at msg->header fields to determine payload filter
virNetMessageEncodePayload(msg, xdrfilter, data)
...send msg->bufferLength worth of data from buffer
To receive a message
msg = virNetMessageNew()
...read VIR_NET_MESSAGE_LEN_MAX of data into buffer
virNetMessageDecodeLength(msg)
...read msg->bufferLength-msg->bufferOffset of data into buffer
virNetMessageDecodeHeader(msg)
...look at msg->header fields to determine payload filter
virNetMessageDecodePayload(msg, xdrfilter, data)
...run payload processor
* src/Makefile.am: Add to libvirt-net-rpc.la
* src/rpc/virnetmessage.c, src/rpc/virnetmessage.h: Internal
message handling API.
* testutils.c, testutils.h: Helper for printing binary differences
* virnetmessagetest.c: Validate all XDR encoding/decoding
Make virtTestLoadFile allocate the buffer to read the file into.
Fix logic error in virtTestLoadFile, stop reading on the first empty line.
Use virFileReadLimFD in virtTestCaptureProgramOutput to avoid manual
buffer handling.
A few of the tests were missing basic sanity checks, while most
of them were doing copy-and-paste initialization (in fact, some
of them pasted the argc > 1 check more than once!). It's much
nicer to do things in one common place, and minimizes the size of
the next patch that fixes getcwd usage.

Before this patch, the testsuite was noisy:
TEST: qemuargv2xmltest
........................................ 40
................20:41:28.046: warning : qemuParseCommandLine:6565 : unknown QEMU argument '-unknown', adding to the qemu namespace
20:41:28.046: warning : qemuParseCommandLine:6565 : unknown QEMU argument 'parameter', adding to the qemu namespace
. 57 OK
PASS: qemuargv2xmltest
It's not a real failure (which is why the test was completing
successfully), so much as an intentional warning to the user that use
of the qemu namespace has the potential for undefined effects that
leaked through the default logging behavior. After this patch series,
all tests can access any logged data, and this particular test can
explicitly check for the presence or absence of the warning, such that
the test output becomes:
TEST: qemuargv2xmltest
........................................ 40
................. 57 OK
PASS: qemuargv2xmltest
* tests/testutils.h (virtTestLogContentAndReset): New prototype.
* tests/testutils.c (struct virtTestLogData): New struct.
(virtTestLogOutput, virtTestLogClose, virtTestLogContentAndReset):
New functions.
(virtTestMain): Always capture log data emitted during tests.
* tests/qemuargv2xmltest.c (testCompareXMLToArgvHelper, mymain):
Use flag to mark which tests expect noisy stderr.
(testCompareXMLToArgvFiles): Add parameter to test whether stderr
was appropriately silent.
Only print out '.' for each test case, full test output can be
re-enabled with VIR_TEST_VERBOSE=1, or VIR_TEST_DEBUG=XXXX
Sample output now looks like
TEST: statstest
........................................ 40
................................... 75 OK
PASS: statstest
TEST: qparamtest
................................ 32 OK
PASS: qparamtest
TEST:
............ 12 OK
Provide a simple interface for other tests to lookup the testDebug variable.
Also remove a redundant error message in interface tests.
If anyone feels inclined to change this env variable to match the existing
LIBVIRT_* format, it should now be easier to do so.
