include header files/source file in ggml

include file in ggml distribute in different dirs, as a library include expose to the user, other header file use internel.

includes

1. ggml-alloc.h: about tensor and compute graph allocation, also include define of backend buffer and talloc.
2. ggml-backend.h: about all of backend, dev/buffer type/buffer/graph and so on. Also include some api can register some event and do schedule.
3. ggml-cpp.h: include some cpp helper define.
4. ggml.h: include all the basic of ggml. aboutr macro, helper, data type, log, kernel op, all you want in this file.
5. ggml-opt.h: include some api about backend train.
6. ggml-gguf.h: something about gguf format design.
7. ggml-cpu.h: something about cpu backend api.

src include

the src include is internel ggml use.

1. ggml-backend-impl.h: direct how the backend implement, also include buffer type/buffer struct and so on.
2. ggml-impl.h: direct how the kernel op and compute implement, also include some fp convert function.
3. ggml-quants.h: include some quantize api.
4. ggml-threads.h: include some threads api, just barrier.
5. ggml-common.h: quantize data type struct define in this.

src/ggml-cpu include

1. binary-ops.h,unary-ops.h and ops.h: different type kernel ops api define.
2. vec.h: some vec op and vec helper.
3. simd-mapping.h: abstract different arch's simd, risc-v not in it.
4. ggml-cpu-traits.h: extra traits define for cpu, use for extension such like amx.
5. ggml-cpu-quants.h: cpu quantize function define, include normal quantize and vector.
6. ggml-cpu-impl.h: some arch specific data type define, some vector type abstract, and cpu computer param struct define there.
7. commom.h: some fp converter function.

src

1. ggml-alloc.c: alloc inplemention, internel struct include galloc/tdynalloc define here.
2. ggml-backend.cpp: backend api implement, it is strange cpu backend buffer implement in here, maybe because cpu backend seen as default backend.
3. ggml-backend-reg.cpp: aboue backend device register.
4. ggml-opt.cpp: something about model opt.
5. ggml-quants.c: quants implement.
6. ggml.c: general function implement.

src/ggml-cpu

1. ggml-cpu.c: all cpu compute implement here, about forward compute and so on.
2. ggml-cpu.cpp: cpu backend implement, not include buffer, include device compute and so on.
3. ggml-cpu-traits.cpp: extra traits detect and use, include extra buffer and work size.
4. ops.cpp and binary-ops.cpp: op implement.
5. vec.cpp: vec implement.
6. ggml-cpu-quants: also quants implement.
