Subject[PATCH 3/3] perf tui: Add workaround for slang < 2.1.4
Date
From: Arnaldo Carvalho de Melo <acme@redhat.com>

Older versions of the slang library didn't used the 'const' specifier,
causing problems with modern compilers of this kind:

util/newt.c:252: error: passing argument 1 of ‘SLsmg_printf’ discards
qualifiers from pointer target type

Fix it by using some wrappers that when needed const the affected
parameters back to plain (char *).
