[LTP] [PATCH RFC 0/2] Refactor test state handling and clarify naming in LTP

[Li Wang]

This patch series introduces two improvements to the test infrastructure:

1: Introduce shared struct context for runtime test state

   This refactor consolidates scattered global runtime state variables
   into a single struct context, which is stored in a new struct ipc_region.
   This change is aimed at improving test robustness and maintainability
   by enabling structured state sharing between parent and child processes,
   particularly for tests requiring checkpointing or fork/exec workflows.


2: Rename tid to tcid

   This is a simple but meaningful rename to avoid confusion between thread
   ID (tid) and test case ID (tcid). This improves code clarity and avoids
   misinterpretation during code review.

CI Job: https://github.com/wangli5665/ltp/actions/runs/14989986133

Also manually tested by myself on RHEL-10.
