4ce06ba6f4 src: Export virDomainMemoryAccessType*String
These are already exported at header file level because of
VIR_ENUM_DECL being in numa_conf.h. However, they are not being
exported at object level because of missing libvirt_private.syms
record.

4b2e0ed6e3 storage: Convert virStoragePoolObjList to use virObjectRWLockable
Now that we have a private storage pool list, we can take the next
step and convert to using objects. In this case, we're going to use
RWLockable objects (just like every other driver) with two hash
tables for lookup by UUID or Name.

Along the way the ForEach and Search API's will be adjusted to use
the related Hash API's and the various FindBy functions altered and
augmented to allow for HashLookup w/ and w/o the pool lock already
taken.

After virStoragePoolObjRemove we will need to virObjectUnref(obj)
after to indicate the caller is "done" with it's reference. The
Unlock occurs during the Remove.

The NumOf, GetNames, and Export functions all have their own callback
functions to return the required data and the FindDuplicate code
can use the HashSearch function callbacks.

For now it'll just call the virStoragePoolObjUnlock, but a future

baca005367 util: Introduce virBitmapShrink
Sometimes the size of the bitmap matters and it might not be guessed correctly
when parsing from some type of input.  For example virBitmapNewData() has Byte
granularity, virBitmapNewString() has nibble granularity and so on.
virBitmapParseUnlimited() can be tricked into creating huge bitmap that's not
needed (e.g.: "0-2,^99999999").  This function provides a way to shrink the
bitmap.  It is not supposed to free any memory.

Currently for on_poweroff and on_reboot we allow only subset of actions
that are allowed for on_crash.  This was covered in parse time using
two different enums.  Now to make sure that we don't allow setting
actions that are not supported we need to check it while validating
