Detailed Description

Logging macros and configuration for libmemalloc.

Provides logging utilities for libmemalloc, including log level control (ERROR, WARNING, INFO, DEBUG), ANSI color output, and automatic file, function, and line reporting for each log entry. Supports GCC-specific built-in printing as well as standard printf for other compilers.
