[Toybox] [PATCH] Implement tail -f.

[enh]

ping?

i assume we'll want a follow-up change adding error-checking here:

-  TT.files[TT.file_no].fd = dup(fd);
-  TT.files[TT.file_no].path = strdup(name);
+  TT.files[TT.file_no].fd = xdup(fd);
+  TT.files[TT.file_no].path = xstrdup(name);

and this can probably just use toybuf?

-      #define STR(x) #x
-      char path[sizeof("/proc/self/fd/" STR(INT_MIN))];
-
-      snprintf(path, sizeof(path), "/proc/self/fd/%d", TT.files[i].fd);
-
-      TT.files[i].wd = inotify_add_watch(infd, path, IN_MODIFY);
+      snprintf(toybuf, sizeof(toybuf), "/proc/self/fd/%d", TT.files[i].fd);
+      TT.files[i].wd = inotify_add_watch(infd, toybuf, IN_MODIFY);

but this has already been useful debugging (device-side) adbd bugs...
