login_cap.c: Don't set errno to ERANGE on memory allocation failure

Modified functions: login_getcaptime(), login_getcapnum(),
login_getcapsize().

They all call cgetstr(), which returns -2 on such conditions and already
sets errno to ENOMEM, arguably the appropriate value for these functions
as well.

No in-tree consumer currently checks for errno on error reported by
these functions, so this change has no other code impact.

Make some use of reallocarray, attempting to limit it to cases where the
parameters are unsigned and there is some theoretical chance of overflow.

Update some comments, mostly regarding LOGIN_MECLASS and ~/.login_conf.

Properly spell default in a comment.

Bring the description for login_getclassbyname in sync with the function's
arguments. The function has as a second argument a struct passwd * pointer,
not a directory name.

(mostly) Clean up some const warnings here. The code takes some liberties
because it is the originator of various const strings and knows that they
came from malloc.

ANSIfy, WARNSify, CONSTify. Bit of style(9)-ify.
