Relax the restriction that the hash table key must be a string
by allowing an arbitrary hash code generator + comparison func
to be provided

* util/hash.c, util/hash.h: Allow any pointer as a key
* internal.h: Include stdbool.h as standard.
* conf/domain_conf.c, conf/domain_conf.c,
  conf/nwfilter_params.c, nwfilter/nwfilter_gentech_driver.c,
  nwfilter/nwfilter_gentech_driver.h, nwfilter/nwfilter_learnipaddr.c,
  qemu/qemu_command.c, qemu/qemu_driver.c,
  qemu/qemu_process.c, uml/uml_driver.c,
  xen/xm_internal.c: s/char */void */ in hash callbacks

Since the deallocator is passed into the constructor of
a hash table it is not desirable to pass it into each
function again. Remove it from all functions, but provide
a virHashSteal to allow a item to be removed from a hash
table without deleteing it.

* src/util/hash.c, src/util/hash.h: Remove deallocator
  param from all functions. Add virHashSteal
* src/libvirt_private.syms: Add virHashSteal
* src/conf/domain_conf.c, src/conf/nwfilter_params.c,
  src/nwfilter/nwfilter_learnipaddr.c,
  src/qemu/qemu_command.c, src/xen/xm_internal.c: Update
  for changed hash API

Remove the <stdbool.h> header from all source files / headers
and just put it into internal.h

* src/internal.h: Add <stdbool.h>

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.

(qemuDomainPCIAddressSetFree): Likewise.
* src/qemu/qemu_process.c (qemuProcessWaitForMonitor): Likewise.

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.

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.

* src/util/hash.c (virHashGrow) [DEBUG_GROW]: Use modern logging.
Reported by Christophe Fergeau.

A couple of allocation were not calling virReportOOMError on allocation
errors

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

* src/util/hash.c: virHashAddEntry and virHashUpdateEntry were missing NULL
  checks on strdup
* AUTHORS: add Christophe Fergeau

Building with --disable-nls exposed many new warnings like these:
virsh.c:4952: warning: format not a string literal and no format ...
util.c:163: warning: format not a string literal and no format arguments
All but one of the following changes add a "%s" argument before
the offending _(...) argument.

This was the only manual change:
* src/lxc_driver.c (lxcVersion): Use %s and strerror(errno)
rather than %m, to avoid a warning from gcc -Wformat-security.
