According to style(9):
> normally, include <sys/types.h> OR <sys/param.h>, but not both.
(<sys/param.h> already includes <sys/types.h> when LOCORE is not defined).
We have an nitems() macro in the <sys/param.h> header that is
convenient to re-use as it makes things easier to read.
Given that it is available already without adding additional
headers and other parts of libc already use it, extend a bit
more its use.
While here also cleanup some surrounding code; particularly
drop some malloc() casts.
Found with devel/coccinelle.

This avoids reproducing the lex logic which had dependencies set wrong
and used an intermediate file for modifying the YY_BUF_SIZE.
This has only been possible since flex 2.5.37 was imported in r250873,
which uses #ifndef YY_BUF_SIZE.

nslexer.o depends on nsparser.h, which is already added by bsd.lib.mk
and .depend.
This reverts r237402.

- In a PF_LOCAL address, "hostname" must begins with '/' and "servname"
is always NULL. All of ai_flags are ignored.
- PF_UNSPEC matches PF_LOCAL. EAI_SERVICE is not returned to make
AF-independent programming easier; "servname" is always ignored
in PF_LOCAL. In practice, PF_INET* and PF_LOCAL are
mutually-exclusive because a hostname which begins with '/' is invalid
in PF_INET*. No domain name resolution is performed for a PF_LOCAL address.

This silence a warning brought up by valgrind whenever if_nametoindex
is used. This was already discussed in PR 166483, but the code
committed in r234329 guards the initilization with #ifdef PURIFY.
Therefore, valgrind still complains. Since this code is not performance
critical, always zero out the local variable to silence valgrind.

the buffer. (n == hostlen) also means the buffer length was
too short.
- Use sdl->sdl_data only when (sdl->sdl_nlen > 0 && sdl->sdl_alen == 0)
to prevent redundant output.
are aliases for the syscall stubs and are plt-interposed, to the
libc-private aliases of internally interposed sigprocmask() etc.
Since e.g. _sigaction is not interposed by libthr, calling signal()
removes thr_sighandler() from the handler slot etc. The result was
breaking signal semantic and rtld locking.
The added __libc_sigprocmask and other symbols are hidden, they are
not exported and cannot be called through PLT. The setjmp/longjmp
functions for x86 were changed to use direct calls, and since
PIC_PROLOGUE only needed for functional PLT indirection on i386, it is
removed as well.
The PowerPC bug of calling the syscall directly in the setjmp/longjmp
implementation is kept as is.

- Use pid_t for PIDs
- Note that we are at the same level of OpenBSD's counterpart of
revision 1.7 (r94757).

recv() and send()'s calls to recvfrom() and sendto() are much like
waitpid()'s call to wait4(), and likewise need not allow PLT interposing on
the called function.
