[Libguestfs] use STREQ(a,b), not strcmp(a,b) == 0

The series below makes changes like these mechanically, one class of change per change-set: strcmp(...) == 0 to STREQ(...) strcmp(...) != 0 to STRNEQ(...) strncmp(...) == 0 to STREQLEN(...) strncmp(...) != 0 to STRNEQLEN(...) strcasecmp(...) == 0 to STRCASEEQ(...) strcasecmp(...) != 0 to STRCASENEQ(...) strncasecmp(...) == 0 to STRCASEEQLEN(...) strncasecmp(...) != 0 to STRCASENEQLEN(...) Then it enables the "make syntax-check" tests to ensure no offending (convertable) use is introduced. But there's one twist. In order for the substitution commands to work as-is, I first converted str*cmp functions, and *then* added the #define stmts. Afterwards, I used git rebase -i to move the final #define-adding-commit to precede the others. That makes it so that the code compiles after each new change set. If I'd added the #defines before performing the substitutions, I would have had to make the commands more involved to keep them from transforming the #defines. Just noticed that the actual definitions are over-parenthesized, and can be simplified to this: #define STREQ(a,b) (strcmp(a,b) == 0) #define STRNEQ(a,b) (!STREQ(a,b)) #define STRCASEEQ(a,b) (strcasecmp(a,b) == 0) #define STRCASENEQ(a,b) (!STRCASEEQ(a,b)) #define STREQLEN(a,b,n) (strncmp(a,b,n) == 0) #define STRNEQLEN(a,b,n) (!STREQLEN(a,b,n)) #define STRCASEEQLEN(a,b,n) (strncasecmp(a,b,n) == 0) #define STRCASENEQLEN(a,b,n) (!STRCASEEQLEN(a,b,n)) #define STRPREFIX(a,b) (strncmp((a),(b),strlen((b))) == 0) I'll adjust to use the above tomorrow. --------------------------------------------- were done mechanically. Only 1 and 10 were done manually. This has not yet passed "make check", possibly due to unrelated problems.
