* Make read(2) return EISDIR on directories.jca2016-09-301-4/+6
| | | | | | | | | | | Years ago Theo made read(2) return 0 on directories, instead of dumping the directory content. Another behavior is allowed as an extension by POSIX, returning an EISDIR error, as used on a few other systems. This behavior is deemed more useful as it helps spotting errors. This implies that it might break some setups. Ports bulk builds by ajacoutot@ and naddy@, ok millert@ bluhm@ naddy@ deraadt@

* Delete some abstraction that we don't and won't need.schwarze2016-09-0515-405/+67
| | | | | | | | | | | | | | | | Declare functions rather than generating declarations with macros. Just call functions rather than mainting function pointer tables. Purge unused arguments. Simplify mbstate_t casting. Garbage collect one empty and one unused function. As a bonus, make mbsinit(3) work at all, it returned garbage in the past due to a missing cast when passing mbstate_t. Apart from that, no functional change. No libc bump needed; only private functions are removed and change prototype and only private structs change size. OK stsp@ mpi@; deraadt@ likes the general direction.
