MAJOR_IN_MKDEV and MAJOR_IN_SYSMACROS from libvirt which makes the
AC_HEADER_MAJOR useless.

There is no need to have DRIVER_MODULES_LIBS as it's used only for
libvirt.so. The other places are using DLOPEN_LIBS directly and dlopen
is required if building with libvirtd.
It's mandatory since <5aec02dc37623bf739d1edd8f2be3e4ad9f94ff5>.

virFileIsAccessible does not return true on accessible
directories. Check whether it set EISDIR and only
then assume the directory is inaccessible.
Return 0 (not found) instead of 1 (found),
since the bridge driver taints the network based on
this return value, not whether the hook actually ran.
Remove the bogus check from virHookCall, since it already
checks the virHooksFound bitmap that was filled before
by virHookCheck.

When preparing for the removal of GNULIB commit 18dca21a32 removed the
unneeded O_DIRECTORY, but unfortunately started opening the directory for
writing which fails every time for a directory. There is also no need for that
as flock() works on O_RDONLY file descriptor as well, even for LOCK_EX.

libxlMakeNic was calling g_strdup(virBufferCurrentContent(&buf)) to
make a copy of the buffer contents, and then later freeing the buffer
without ever using it again. Instead of this extra strdup, just
transfer ownership of the virBuffer's string with
virBufferContentAndReset(), and be done with it.

There are several calls to virBufferFreeAndReset() when functions
encounter an error, but the caller never uses the virBuffer once an
error has been encountered (all callers detect error by looking at the
function return value, not the contents of the virBuffer being
operated on), and now that all virBuffers are auto-freed there is no
reason for the lower level functions like these to spend time freeing
a buffer that is guaranteed to be freed momentarily anyway.

The latter function is guaranteed to always clear out the virBuffer

In most cases this eliminates one or more calls to
virBufferClearAndReset(), but even when it doesn't it's better because:
1) it makes the code more consistent, making it more likely that new
contributors who are "learning by example" will to the right thing.
2) it protects against future modifications that might have otherwise
needed to add a virBufferClearAndReset()
3) Currently some functions don't call virBufferClearAndReset() only
because they're relying on some subordinate function to call it for
them (e.g. bhyveConnectGetSysinfo() in this patch relies on
virSysinfoFormat() to clear out the buffer when there is an
error). I think this is sloppy behavior, and that the toplevel
function that defines and initializes the buffer should be the
function clearing it at the end.

The output of vcpupin and emulatorpin for a domain with vcpu
placement='static' is based on a default bitmap that contains
all possible CPUs in the host, regardless of the CPUs being offline
or not. E.g. for a Linux host with this CPU setup (from lscpu):
On-line CPU(s) list: 0,8,16,24,32,40,(...),184
Off-line CPU(s) list: 1-7,9-15,17-23,25-31,(...),185-191
And a domain with this configuration:
<vcpu placement='static'>1</vcpu>
'virsh vcpupin' will return the following:
$ sudo ./run tools/virsh vcpupin vcpupin_test
VCPU CPU Affinity
----------------------
0 0-191
This is benign by its own, but can make the user believe that all
CPUs from the 0-191 range are eligible for pinning. Which can lead
to situations like this:
$ sudo ./run tools/virsh vcpupin vcpupin_test 0 1
error: Invalid value '1' for 'cpuset.cpus': Invalid argument
This is exarcebated by the fact that 'virsh vcpuinfo' considers only
available host CPUs in the 'CPU Affinity' field:
$ sudo ./run tools/virsh vcpuinfo vcpupin_test
(...)
CPU Affinity: y-------y-------y-------(...)
This patch changes the default bitmap of vcpupin and emulatorpin, in
the case of domains with static vcpu placement, to all available CPUs
instead of all possible CPUs. Aside from making it consistent with
the behavior of 'vcpuinfo', users will now have one less incentive to
try to pin a vcpu in an offline CPU.

The idea is to have a function that calls virHostCPUGetOnlineBitmap()
but, instead of returning NULL if the host does not have CPU
offlining capabilities, fall back to a bitmap containing all
present CPUs.
Next patch will use this helper in two other places.

This function reads the string in sysfspath/cpu/present and
parses it manually to retrieve the number of present CPUs.
virHostCPUGetPresentBitmap() reads and parses the same file,
using a more robust parser via virBitmapParseUnlimited(),
but returns a bitmap. Let's drop all the manual parsing done
here and simply return the size of the resulting bitmap
from virHostCPUGetPresentBitmap().
Given that no more parsing is being done manually in the function,
rename it to virHostCPUCountLinux().
