Chairn a69dc599a9 Huge variable naming format
Fix pointer and pointer array variable naming

Huge renaming to match our rules

Used regex: (?!(return|delete)\b)\b\w+ (m_|ms_|g_|gs_|s_)[^a]\w+\[
            (?!(return|delete)\b)\b\w+ (?!(m_|ms_|g_|gs_|s_))[^a]\w+\[

Further format static variables

Format almost all pointer names accordingly

Used regex: (?!(return)\b)\b\w+
\*(?!(m_p|p|s_p|m_ap|s_ap|g_p|g_ap|ap|gs_ap|ms_ap|gs_p|ms_p))\w+\b[^:\(p]

clang-format

Fix CI fail

Fix misnamed non pointer as pointer and non array as array

Used regex: (?!(return|delete)\b)\b\w+ (m_|ms_|g_|gs_|s_)p\w+\b
            (?!return\b)\b\w+ (ms_|m_|g_|gs_|s_)a\w+\b[^\[]

Revert to SCREAMING_SNAKE_CASE and reinstate dead code
