Move common testing code which doesn't need linking with GParted objects
into the common module. Move the remaining common code used to print
GParted objects using the insertion operator (operator<<) into the
insertion_operators module. Split the common code like this so that the
operator<<(std::ostream&, const OperationDetail&) function is not
included in test_PipeCapture and it is not forced to link with all the
non-UI related GParted objects.
The Automake manual provides guidance that when a header belongs to a
single program it is recommended to be listed in the program's _SOURCES
variable and for a directory only containing header files listing them
in the noinst_HEADERS variable is the right variable to use [1].
However the guidance doesn't cover this case for common.h and
insertion_operators.h; header files in a directory with other files and
used by multiple programs. So just because we have gparted_core_OBJECTS
(normal Makefile, not Automake special variable) listing objects to link
with, choose to use noinst_HEADERS Automake variable to list needed
headers.
[1] GNU Automake manual, 9.2 Header files
https://www.gnu.org/software/automake/manual/html_node/Headers.html
"Usually, only header files that accompany installed libraries
need to be installed. Headers used by programs or convenience
libraries are not installed. The noinst_HEADERS variable can be
used for such headers. However, when the header belongs to a
single convenience library or program, we recommend listing it
in the program's or library's _SOURCES variable (see Defining
program sources) instead of in noinst_HEADERS. This is clearer
for the Makefile.am reader. noinst_HEADERS would be the right
variable to use in a directory containing only headers and no
associated library or program.
All header files must be listed somewhere; in a _SOURCES
variable or in a _HEADERS variable. Missing ones will not
appear in the distribution.

Closes#220 - Format to Cleared not clearing "pdc" ataraid signature
Initially just testing erasing of Intel Software RAID signatures.
Chosen because it was expected to work, but turned out not to be true in
all cases.
The code needs to initialise GParted_Core::mainthread, construct
Gtk::Main() and execute xvfb-run because of this call chain:
GParted_Core::erase_filesystem_signatures()
GParted_Core::settle_device()
Utils::execute_command ("udevadm settle ...")
status.foreground = (Glib::Thread::self() == GParted_Core::mainthread)
Gtk::Main::run()
This was also needed when testing file system interface classes as
discussed in commits [1][2].
The test fails like this:
$ ./test_EraseFileSystemSignatures
...

[ OK ] EraseFileSystemSignaturesTest.IntelSoftwareRAIDAligned (155 ms)

This signature is not being cleared when the device/partition/image size
is 512 bytes smaller than a whole MiB because the last 3.5 KiB is left
unwritten. This is because the last block of zeros written is 8 KiB
aligned to 4 KiB at the end of the device.
