[PATCH 0/13] rtla: Code robustness and maintainability improvements

[Wander Lairson Costa <wander@redhat.com>]

This patch series enhances the robustness and maintainability of the
RTLA (Real-Time Linux Analysis) tool through systematic improvements
to error handling, code clarity, and consistency.

The changes strengthen defensive programming practices throughout the
codebase by improving input validation and memory management. Several
new helper functions and macros are introduced to reduce code duplication
and provide safer, more readable alternatives to common operations. The
series also consolidates duplicate logic across modules and adopts
standard conventions where appropriate.

These improvements make the code more resilient and easier to maintain
while preserving existing functionality and behavior.

Wander Lairson Costa (13):
  rtla: Check for memory allocation failures
  rtla: Use strdup() to simplify code
  rtla: Introduce for_each_action() helper
  rtla: Replace atoi() with a robust strtoi()
  rtla: Simplify argument parsing
  rtla: Use strncmp_static() in more places
  rtla: Introduce timerlat_restart() helper
  rtla: Use standard exit codes for result enum
  rtla: Exit if trace output action fails
  rtla: Remove redundant memset after calloc
  rtla: Replace magic number with MAX_PATH
  rtla: Remove unused headers
  rtla: Fix inconsistent state in actions_add_* functions
