03ba07cb73 hash: make virHashFree more free-like
Two-argument free functions are uncommon; match the style elsewhere
by caching the callback at creation.

* src/util/hash.h (virHashCreate, virHashFree): Move deallocator
argument to creation.
* cfg.mk (useless_free_options): Add virHashFree.
* src/util/hash.c (_virHashTable): Track deallocator.
(virHashCreate, virHashFree): Update to new signature.
* src/conf/domain_conf.c (virDomainObjListDeinit)
(virDomainObjListInit, virDomainDiskDefForeachPath)
(virDomainSnapshotObjListDeinit, virDomainSnapshotObjListInit):
Update callers.
* src/conf/nwfilter_params.c (virNWFilterHashTableFree)
(virNWFilterHashTableCreate): Likewise.
* src/conf/nwfilter_conf.c (virNWFilterTriggerVMFilterRebuild):
Likewise.
* src/cpu/cpu_generic.c (genericHashFeatures, genericBaseline):
Likewise.
* src/xen/xm_internal.c (xenXMOpen, xenXMClose): Likewise.
* src/nwfilter/nwfilter_learnipaddr.c (virNWFilterLearnInit)
(virNWFilterLearnShutdown): Likewise.
* src/qemu/qemu_command.c (qemuDomainPCIAddressSetCreate)
(qemuDomainPCIAddressSetFree): Likewise.
* src/qemu/qemu_process.c (qemuProcessWaitForMonitor): Likewise.

7f1c65e551 factor common code in virHashAddEntry and virHashUpdateEntry
The only difference between these 2 functions is that one errors
out when the entry is already present while the other modifies
the existing entry. Add an helper function with a boolean argument
indicating whether existing entries should be updated or not, and
use this helper in both functions.

5c5880e047 add hash table rebalancing in virHashUpdateEntry
The code in virHashUpdateEntry and virHashAddEntry is really
similar. However, the latter rebalances the hash table when
one of its buckets contains too many elements while the former
does not. Fix this discrepancy.

7adb3fb739 call virReportOOMError when appropriate in hash.c
A couple of allocation were not calling virReportOOMError on allocation
errors

* src/util/hash.c: add the needed call in virHashCreate and
  virHashAddOrUpdateEntry

  checks on strdup
* AUTHORS: add Christophe Fergeau

cf577653dc Remove bogus const annotations to hash iterator
Most of the hash iterators need to modify either payload of
data args. The const annotation prevents this.

* src/util/hash.h, src/util/hash.c: Remove const-ness from
  virHashForEach/Iterator
* src/xen/xm_internal.c: Remove bogus casts
