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

Coverity reported a memleak in the test added in 7efd5fd1b0. In case
the code will be broken and the code will actually parse a faulty bitmap
the resulting pointer would be leaked. Free it although that shouldn't
ever happen.
Previous patch fixed an issue where, when parsing a bitmap from the
string, the bounds of the bitmap weren't checked. That flaw resulted into
crashes. This test tests that case to avoid it in the future.
Convert the type of loop iterators named 'i', 'j', k',
'ii', 'jj', 'kk', to be 'size_t' instead of 'int' or
'unsigned int', also santizing 'ii', 'jj', 'kk' to use
the normal 'i', 'j', 'k' naming

We had an easy way to iterate set bits, but not for iterating
cleared bits.
* src/util/virbitmap.h (virBitmapNextClearBit): New prototype.
* src/util/virbitmap.c (virBitmapNextClearBit): Implement it.
* src/libvirt_private.syms (bitmap.h): Export it.
* tests/virbitmaptest.c (test4): Test it.
This bug leads to getting incorrect vcpupin information via
qemudDomainGetVcpuPinInfo() API when the number of maximum
cpu on a host falls into a range such as 31 < ncpus < 64.
gcc warning:
left shift count >= width of type
The following bug is such the case

Sometimes it's handy to know how many bits are set.
* src/util/bitmap.h (virBitmapCountBits): New prototype.
(virBitmapNextSetBit): Use correct type.
* src/util/bitmap.c (virBitmapNextSetBit): Likewise.
(virBitmapSetAll): Maintain invariant of clear tail bits.
(virBitmapCountBits): New function.
* src/libvirt_private.syms (bitmap.h): Export it.
* tests/virbitmaptest.c (test2): Test it.
https://www.gnu.org/licenses/gpl-howto.html recommends that
the 'If not, see <url>.' phrase be a separate sentence.
* tests/securityselinuxhelper.c: Remove doubled line.
* tests/securityselinuxtest.c: Likewise.
* globally: s/; If/. If/
Commit ee3d3893 missed the fact that (unsigned char)<<(int)
is truncated to int, and therefore failed for any bitmap data
longer than four bytes.
Also, I failed to run 'make syntax-check' on my commit 4bba6579;
for whatever odd reason, ffs lives in a different header than ffsl.
* src/util/bitmap.c (virBitmapNewData): Use correct shift type.
(includes): Glibc (and therefore gnulib) decided ffs is in
<strings.h>, but ffsl is in <string.h>.
* tests/virbitmaptest.c (test5): Test it.
In many places we store bitmap info in a chunk of data
(pointed to by a char *), and have redundant codes to
set/unset bits. This patch extends virBitmap, and convert
those codes to use virBitmap in subsequent patches.
