Summary of Changes

Hello @doomedraven, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a significant change to the project's logging infrastructure by migrating from BSON to MessagePack. This modernization effort aims to improve the efficiency and performance of log data serialization. The changes span across project configuration files and the core logging implementation, ensuring a seamless transition to the new binary format.

Highlights

• Logging Serialization Migration: The core logging mechanism has been migrated from BSON (Binary JSON) to MessagePack (mpack), a more efficient binary serialization format. This involves replacing all BSON-related function calls and data structures with their mpack equivalents.
• Project Configuration Updates: The capemon.vcxproj and capemon.vcxproj.filters files have been updated to remove BSON library dependencies and include paths, and to incorporate the new mpack.c and mpack.h files into the build process.
• Refactored Log Generation Logic: The log.c file has undergone significant refactoring. Functions responsible for serializing various data types (integers, pointers, strings, variants, buffers, argument lists) have been rewritten to use the mpack_writer_t API. The main loq function, which generates log entries, has been completely adapted to the new MessagePack format.
• Adjusted Log Deduplication: The log deduplication logic within the loq function has been updated to accommodate MessagePack's variable-length encoding. The lastlog_t structure now uses an offset (repeat_offset) instead of a direct pointer to manage the repetition count, ensuring safe in-place updates for frequently occurring log messages.

Code Review

This pull request replaces the BSON logging library with MessagePack (mpack). The changes are extensive, touching project files and the core logging logic. While the migration is a good step towards a more modern and potentially more efficient serialization format, I've found several critical and high-severity issues that need to be addressed. These include memory management bugs that could lead to double-frees, incorrect path string handling, and a broken macro that will likely cause a crash. There are also some minor style issues that affect code readability.
