This patch moves `ReadFileSync` and `WriteFileSync` from `src/util.cc` to `src/node_file_utils.cc`, consolidates the implementation to reuse code, and adds a few more enhancements: For `ReadFileSync`: - Use fstat-based pre-allocation to minimize buffer resizing and repeated reads for bigger files. - Handle various potential overflows in size conversions. - Handle fallback for 0-byte special files. For `WriteFileSync`: - Handle potential partial writes for big enough files and support non-seekable files (with -1 as offset). - Handle 0-byte writes correctly. In both cases, this now avoids hard aborts and return error code for the caller to handle as much as possible, except `std::vector<char> ReadFileSync(FILE* fp)` which is part of the embedder API. This patch uses the new `ReadFileSync` to address a TODO in node_sea.bin.cc.
