This will currently only work for the RelWithDebInfo configuration since asan
does not support the debug crt. for source line information in the reports,
you need a copy of llvm-symbolizer in the blender folder or set the
ASAN_SYMBOLIZER_PATH environment variable to point to it. Currently (as of
6.0.0) llvm-symbolizer does not ship with the binary clang/llvm distribution.

Applying cflags globally can be problematic especially with extern, intern libs.
Now flags from target named will be used when defined,
allowing for developers to define flags for modules they maintain.
Convention is CMAKE_CFLAGS_${UPPERCASE_TARGET_NAME}, (CXXFLAGS for C++).
eg: CMAKE_CFLAGS_BF_BLENDER, CMAKE_CFLAGS_MAKESDNA, CMAKE_CXXFLAGS_CYCLES_KERNEL
On Linux run `make help` for full list of names, MSVC shows these in the solution.

utils to API.
This patch is the root of the GHash rework, all other diff will be based on it:
Reduce average load from 3.0 to 0.75
----------------------------------
This is the big performance booster part, e.g. makes tracing a dyntopo stroke between 25% and 30% faster.
Not much to say about it, aside that it obviously increase memory footprint (about 25% - 30% too).
Add optional shrinking
----------------------------------
I.e. ghashes/gsets can now shrink their buckets array when you remove enough entries. This remains optional and OFF by default.
Add code to use masking instead of modulo
----------------------------------
Buckets indices are obtained from hashes by “reducing” the hash value into the valid bucket range. This can be done either by bit-masking, or using modulo operation.
The former is quicker, but requires real hashes, while the later is slower (average 10% impact on ghash operations) but can also be used as a 'fake' hashing on raw values, like e.g. indices.
In Blender currently not all ghash usages actually hash their keys, so we stick to modulo for now (masking is ifdef’ed out), we may however investigate the benefits of switching to masking with systematic very basic hashing later…
Add various missing API helpers
----------------------------------
I.e. a way to deep-copy a ghash/gset, and a way to (re-)reserve entries (i.e. manually grow or shrink the ghash after its creation).
Various code refactoring
----------------------------------
* Get rid of the 'hack' regarding ghash size when used as gset (it’s simpler and safer to have two structs defined here, and cast pointers as needed).
* Various re-shuffle and factorization in low-level internal code.
* Some work on hashing helpers, introducing some murmur2a-based hashing too.
Thanks a bunch to Campbell for the extensive review work. :)

Release builds will now use lock-free allocator by
default without any internal locks happening.
MemHead is also reduces to as minimum as it's possible.
It still need to be size_t stored in a MemHead in order
to make us keep track on memory we're requesting from
the system, not memory which system is allocating. This
is probably also faster than using a malloc's usable
size function.
Lock-free guarded allocator will say you whether all
the blocks were freed, but wouldn't give you a list
of unfreed blocks list. To have such a list use a
--debug or --debug-memory command line arguments.
Debug builds does have the same behavior as release
builds. This is so tools like valgrind are not
screwed up by guarded allocator as they're currently
are.

also set_source_files_properties() wasn't working for rna_*_gen.c files,
set dna.c and generated data files with generated property too.

- Re-arrange locks, so no actual memory allocation
(which is relatively slow) happens from inside
the lock. operation system will take care of locks
which might be needed there on it's own.
- Use spin lock instead of mutex, since it's just
list operations happens from inside lock, no need
in mutex here.
- Use atomic operations for memory in use and total
used blocks counters.
This makes guarded allocator almost the same speed
as non-guarded one in files from Tube project.
There're still MemHead/MemTail overhead which might
be bad for CPU cache utilization

lite, will also speedup undo.
note: only works with CMake, wasn't able to get this working with scons, complains about same file being built in different environments.

blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.

The butterfly wing flap, causing a nice storm in the rest of blender.
Now all dependencies should point ok again. CMakers, do double-test.

blender_include_dirs(${OPENGL_INCLUDE_DIR})
Apparently this is needed for MSVC in some cases, reported by Tamito Kajiyama r33895.

Also some white space cleaning and removal of redundant parameter.
|
|
also made cmakes output a lot quieter, messages can be uncommented for debugging or added back if other devs need this for some reason.

and endif() which is no longer needed.

reporting missing headers & C files.
this is important so IDE's using CMake integration always get blender headers. - QtCreator & MSVC for eg, probably others too.

- patch from Mike S to enable OpenMP and xcode

Was annoying to use a different editor for cmake only.
theeth says this should be ok with gsoc and merges from branches.

Made sdna and srna work more like how the scons build system is doing it, with separate bf_rna and bf_dna libs being built.

replacement for mmap/munmap on Windows.
Implemented using CreateFileMapping/MapViewOfFile.

different platforms will follow soon. This was just tested against current CVS on MSVC 2005 with Verse, QuickTime, OpenEXR, Player all on.
