directory and adjust environment variable.

- Fixed a couple of whitespace issues.
Using // coverity[...] or /* coverity[...] */ comments in the source
it is possible to suppress specific Coverity errors. The suppressed
error should occur in the line following the comment.
In this case I have suppressed two false positives from Coverity:
(a) We deliberately assign to a NULL pointer in order to cause a
segfault, for testing how the library reacts when this happens.
Coverity flags this, but it is not an error in this case.
(b) Coverity does not model global variables (a known shortcoming).
Therefore the code 'errno = posix_memalign (...)' cannot be modelled
by Coverity, even though the code is correct. Coverity raises a false
positive about this.
(Thanks Kamil Dudka, Coverity)
If there was no quoting character, the options could run off the end
of the string and into whatever string which happened to be following
in memory.
This bug was revealed when libguestfs was compiled on arm.
For the rationale behind this renaming, see:
b8cbe191d0
You can still, for the time being, use
./configure --with-febootstrap-yum-config
but it's preferred to switch to the new option. The new option is
identical, just renamed.
Qe still pass the deprecated --yum-config option to febootstrap
itself, since both old and new febootstrap support this.
For some reason the fs->device field was not set for swap devices.
Apparently this did not matter before (this bug has existed since at
least libguestfs 1.16), but in commit 6ee80b8dac we started to depend
on the fs->device field being non-NULL. This resulted in segfaults
when inspecting any guest which had a swap device, eg:
#0 __strcmp_sse42 () at ../sysdeps/x86_64/multiarch/strcmp-sse42.S:164
#1 0x00007ffff7d740cb in parent_device_already_probed (g=0x703a70,
partition=0x6f79b0 "/dev/vda4") at inspect.c:156
#2 0x00007ffff7d73e00 in guestfs__inspect_os (g=0x703a70) at inspect.c:83
#3 0x00007ffff7cee11d in guestfs_inspect_os (g=0x703a70) at actions-1.c:397
This commit sets fs->device to the device name.
(Thanks Matthew Booth for first noticing this problem.)
If ntfs-3g is not installed, then tests/guests creates a 'windows.img'
file which is zero-sized.
This is problematical because other tests which use this image will
fail at best, or hit RHBZ#847549 (qemu/virtio-scsi bug) at worst.
Change the tests which use windows.img so they skip if 'windows.img'
has zero size.
If you want to selectively run tests, or if the test suite fails half
way through, use:
make print-subdirs
to print the subdirectories, select the ones you want to run / the
remaining ones, and do:
make check SUBDIRS="..."
