* llama : use posix_madvise() instead of madvise() derived from BSD
sed -i 's,\<madvise\>,posix_&,g;s,\<MADV_,POSIX_&,g' llama.cpp
* ggml : use sysconf(_SC_PAGESIZE) instead of getpagesize() derived from BSD
sed -i 's,getpagesize(),sysconf(_SC_PAGESIZE),g' ggml.c
* metal : use sysconf(_SC_PAGESIZE) instead of getpagesize() derived from BSD
sed -i 's,getpagesize(),sysconf(_SC_PAGESIZE),g' ggml-metal.m
* convert-llama-ggmlv3-to-gguf: Try to handle files older than GGJTv3
* Better error messages for files that cannot be converted
* Add file type to GGUF output
* Rename to convert-llama-ggml-to-gguf.py
* Include original file type information in description
* Improve some informational output
* Guard against all weights in a super-block being zero
* Also guard against extremely small weights
