[LTP] [RFC PATCH 1/2] lib: add TST_RES_ serious macros

[Cyril Hrubis]

Hi!
> This patch introduces new macros to encapsulate existing tst_res and
> tst_brk functions in the LTP library. These macros simplify the usage
> of tst_ functions by providing a more user-friendly interface for
> generating standardized test output.
> 
>   TST_RES_TINFO()    -> tst_res(TINFO, ...)
>   TST_RES_TWARN()    -> tst_res(TINFO, "WARNING: ", ...)
>   TST_RES_TPASS()    -> tst_res(TPASS, ...)
>   TST_RES_TDEBUG()   -> tst_res(TDEBUG, ...)
>   TST_RES_TFAIL()    -> tst_res(TFAIL,  ...)
> 
>   TST_BRK_TCONF()    -> tst_brk(TCONF, ...)
>   TST_BRK_TBROK()    -> tst_brk(TBROK,  ...)
> 
>   TST_RES_TPASS_ER() -> tst_res(TPASS | errno, ...)
>   TST_RES_TFAIL_ER() -> tst_res(TFAIL | errno, ...)
>   TST_BRK_TBROK_ER() -> tst_brk(TBROK | errno, ... )
> 
> The macros handle various scenarios including simple messages and messages
> with error flags, ensuring consistent logging of file and line information.
> 
> Additionally, a new test case in tst_res_macros.c demonstrates the usage
> of these macros.

I actually like the function better. It makes sense to add macros when
they do something more complicated e.g. the TST_EXP_ macros save a lot
of code, but in this case I do not think that they add any value, the
change is only cosmetic.
