Add history and config-struct to recurse For loop detection, a history is mandatory. In the process of also adding a flexible struct to recurse, the recurse-definition was moved to fs.h. The motivation behind the struct is to allow easy extensions to the recurse-function without having to change the prototypes of all functions in the process. Adding flags is really simple as well now. Using the recursor-struct, it's also easier to see which defaults apply to a program (for instance, which type of follow, ...). Another change was to add proper stat-lstat-usage in recurse. It was wrong before.

Un-boolify sbase It actually makes the binaries smaller, the code easier to read (gems like "val == true", "val == false" are gone) and actually predictable in the sense of that we actually know what we're working with (one bitwise operator was quite adventurous and should now be fixed). This is also more consistent with the other suckless projects around which don't use boolean types.

Fix return values in rm(1) and mv(1) by setting rm_status to 1 if removing 1 file in the list fails. Extend this to mv_status in mv(1).

Refactor enmasse() and recurse() to reflect depth The HLP-changes to sbase have been a great addition of functionality, but they kind of "polluted" the enmasse() and recurse() prototypes. As this will come in handy in the future, knowing at which "depth" you are inside a recursing function is an important functionality. Instead of having a special HLP-flag passed to enmasse, each sub- function needs to provide it on its own and can calculate results based on the current depth (for instance, 'H' implies 'P' at depth > 0). A special case is recurse(), because it actually depends on the follow-type. A new flag "recurse_follow" brings consistency into what used to be spread across different naming conventions (fflag, HLP_flag, ...). This also fixes numerous bugs with the behaviour of HLP in the tools using it.
