This commit introduces a new PCI library and associated tools for inspecting and modifying PCI configuration space via Linux sysfs. The following changes were made: - Implemented `pci.c` and `pci.h` for PCI device management, including enumeration, attribute reading, and configuration space access. - Added `setpci` command-line utility for reading and writing PCI configuration registers, with support for filtering devices by vendor, device, and slot. - Created manual pages for `setpci` to document its usage and options. - Developed test scripts for both `lspci` and `setpci` to ensure functionality and correctness of the new features. These additions enhance the ability to interact with PCI devices, providing a robust framework for device management and configuration.
