contrib/, lib/, src/: Use streq() instead of its pattern

Except for the added includes, and the removal of redundant parentheses, this patch can be approximated with the following semantic patch: $ cat ~/tmp/spatch/streq.sp; @@ expression a, b; @@ - strcmp(a, b) == 0 + streq(a, b) @@ expression a, b; @@ - 0 == strcmp(a, b) + streq(a, b) @@ expression a, b; @@ - !strcmp(a, b) + streq(a, b) $ find contrib/ lib* src/ -type f \ | xargs spatch --sp-file ~/tmp/spatch/streq.sp --in-place; $ git restore lib/string/strcmp/streq.h; Signed-off-by: Alejandro Colomar <[email protected]>
