This is a self-locking wrapper around virHashTable. Only a limited set of APIs are implemented now (the ones which are used in the following patch) as more can be added on demand. Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

I almost wrote a hash value free function that just called VIR_FREE, then realized I couldn't be the first person to do that. Sure enough, it was worth factoring into a common helper routine. * src/util/virhash.h (virHashValueFree): New function. * src/util/virhash.c (virHashValueFree): Implement it. * src/util/virobject.h (virObjectFreeHashData): New function. * src/libvirt_private.syms (virhash.h, virobject.h): Export them. * src/nwfilter/nwfilter_learnipaddr.c (virNWFilterLearnInit): Use common function. * src/qemu/qemu_capabilities.c (virQEMUCapsCacheNew): Likewise. * src/qemu/qemu_command.c (qemuDomainCCWAddressSetCreate): Likewise. * src/qemu/qemu_monitor.c (qemuMonitorGetBlockInfo): Likewise. * src/qemu/qemu_process.c (qemuProcessWaitForMonitor): Likewise. * src/util/virclosecallbacks.c (virCloseCallbacksNew): Likewise. * src/util/virkeyfile.c (virKeyFileParseGroup): Likewise. * tests/qemumonitorjsontest.c (testQemuMonitorJSONqemuMonitorJSONGetBlockInfo): Likewise.

'const fooPtr' is the same as 'foo * const' (the pointer won't change, but it's contents can). But in general, if an interface is trying to be const-correct, it should be using 'const foo *' (the pointer is to data that can't be changed). Fix up virhash to provide a const-correct interface: all actions that don't modify the table take a const table. Note that in one case (virHashSearch), we actually strip const away - we aren't modifying the contents of the table, so much as associated data for ensuring that the code uses the table correctly (if this were C++, it would be a case for the 'mutable' keyword). * src/util/virhash.h (virHashKeyComparator, virHashEqual): Use intended type. (virHashSize, virHashTableSize, virHashLookup, virHashSearch): Make const-correct. * src/util/virhash.c (virHashEqualData, virHashEqual) (virHashLookup, virHashSize, virHashTableSize, virHashSearch) (virHashComputeKey): Fix fallout. * src/conf/nwfilter_params.c (virNWFilterFormatParameterNameSorter): Likewise. * src/nwfilter/nwfilter_ebiptables_driver.c (ebiptablesFilterOrderSort): Likewise. * tests/virhashtest.c (testHashGetItemsCompKey) (testHashGetItemsCompValue): Likewise.

Some files are using uint32_t or int64_t without including stdint.h which defines them. Fix this.

Recent discussions have illustrated the potential for DOS attacks with the hash table implementations used by most languages and libraries. https://lwn.net/Articles/474912/ libvirt has an internal hash table impl, and uses hash tables for a variety of purposes. The hash key generation code is pretty simple and thus not strongly collision resistant. This patch replaces the current libvirt hash key generator with the (public domain) Murmurhash3 code. In addition every hash table now gets a random seed value which is used to perturb the hashing code. This should make it impossible to mount any practical attack against libvirt hashing code. * bootstrap.conf: Import bitrotate module * src/Makefile.am: Add virhashcode.[ch] * src/util/util.c: Make virRandom() return a fixed 32 bit integer value. * src/util/hash.c, src/util/hash.h, src/util/cgroup.c: Replace hash code generation with a call to virHashCodeGen() * src/util/virhashcode.h, src/util/virhashcode.c: Add a new virHashCodeGen() API using the Murmurhash3 algorithm.

In preparation for the patch to include Murmurhash3, which introduces a virhashcode.h and virhashcode.c files, rename the existing hash.h and hash.c to virhash.h and virhash.c respectively.

In preparation for conversion over to use the Murmurhash3 algorithm, convert various virHash APIs to use size_t or uint32 for their return values/parameters, instead of the variable size 'unsigned long' or 'int' types

This adds several tests for remaining hash APIs (custom hasher/comparator functions are not covered yet, though). All tests pass both before and after the "Simplify hash implementation".

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.

src/xs_internal.c: implementing domain pointers unification, thread safety and reference counting for domain and connections, this was the last critical change needed before making further progresses at the API level. Still a couple fo things TODO for this, unification at the Python level and adding UUID to hash. All domain/connect alloc and free routines are now centralized in hash.c * docs/APIchunk1.html docs/libvirt-api.xml docs/libvirt-refs.xml docs/html/libvirt-libvirt.html: regenerated the docs, that doesn't change the API.
