Because of copy-paste the temporary directory used for this test
is called "fakesysdir". That's probably misleading.

We use the "vir" prefix pretty consistently in our
APIs, both external and internal, which made these
macros stood out.

There is no reason for it not to be in the utils, all global symbols
under that file already have prefix vir* and there is no reason for it
to be part of DRIVER_SOURCES because that is just a leftover from
older days (pre-driver modules era, I believe).

This function doesn't follow our convention of naming functions.

Instead of hardcoding LIBEXECDIR as the location of the libvirt_iohelper
binary, use virFileFindResource to optionally find it in the current
build directory.

Any source file which calls the logging APIs now needs
to have a VIR_LOG_INIT("source.name") declaration at
the start of the file. This provides a static variable
of the virLogSource type.

The test case average timing code has not been used by any test
case ever. Delete it to remove complexity.

We can't use GNULIB's fprintf-posix due to licensing
incompatibilities. We do already have a portable
formatting via virAsprintf() which we got from GNULIB
though. We can use to create a virFilePrintf() function.

But really gnulib could just provide a 'fprintf'
module, that depended on just its 'asprintf' module.

On RHEL 6.4 (gcc 4.4.7), I got:

fdstreamtest.c: In function 'testFDStreamReadCommon':
fdstreamtest.c:44: error: declaration of 'tmpfile' shadows a global declaration [-Wshadow]

* tests/fdstreamtest.c (testFDStreamReadCommon)
(testFDStreamWriteCommon): Rename 'tmpfile' variable.

Add a test case which exercises the virFDStreamOpenFile
and virFDStreamCreateFile methods. Ensure that both the
synchronous and non-blocking iohelper code paths work.
This validates the regression recently fixed which
broke reading in non-blocking mode
